How is a paper clip made? |
Background
The paper clip is a nearly ubiquitous device, used worldwide to temporally hold papers together. The technology for manufacturing paper clips evolved in the early years of the twentieth century, and has remained virtually unchanged since the 1930s. Paper clips come in several forms, but the one most often seen in common use is called the Gem clip. The origin of the term "Gem" is supposed to have originated from a British firm that began exporting them at least as early as 1907. The term has come to stand for the iconic shape of the oval-within-oval design. Any clip of this shape is called a Gem clip, regardless of the manufacturer. Another type of paper clip sometimes used by archivists and librarians is called the Gothic clip. It has a rectangular shape, with a triangular inner loop. Other distinguishing marks of paper clips are the overall size, the thickness, and quality of the wire, and whether the clip is corrugated or smooth. Most paper clips in the United States are made domestically by a few firms that specialize in their manufacture. These manufacturers put out roughly 20 million lb (9 kg) a year of paper clips.
History
The paper clip evolved to fill a specific need. A large amount of paper could be bound into a book in order to hold the leaves together. Binding was not a viable solution to keep together a few sheets, such as a short set of records or receipts. Though paper was invented in China sometime in the first century A.D., and was widespread in Europe by the thirteenth century, people made do without anything like the modern paper clip until the end of the nineteenth century. People used two general methods to fasten together a few sheets of paper. They could slit the pages in the corner, making two short parallel cuts. Then ribbon or string could be threaded through the slits, the ends tied and often sealed with wax. The second method was to take a common straight pin and pin the sheets together. Machinery to make cheap and uniform quality pins developed early in the nineteenth century. Business people bought boxes of loose pins, sold by the pound and called "bank pins," to use in offices. Both the slit method and the pin method had the same drawback: the paper had to be pierced. Pin holes caused less wear on the paper than slits, yet if pages needed to be unpinned and repinned many times, the pinned corner was subject to a lot of wear, leading to the drooping "dog ear." Pins also had the disadvantage of being sharp enough to prick fingers and tended to rust if left in place for any length of time.
Designs or patents for early paper clips date to the middle of the nineteenth century, but none of these early devices seem to have worked well enough to have made a lasting impression. Some of these were closer in form to what is known today as a binder clip or bulldog clip, and others enfolded the entire corner of the paper within teethed overlays of thin metal. This type of paper fastener was made from stamped sheet metal. Wire forming technology advanced in the mid-nineteenth century, and from about 1870 on, paper clips of various designs competed in Europe and the United States.
The earliest recorded patent for a paper clip was granted by the United States Patent Office to a Pennsylvanian, Matthew Schooley, in 1898. Schooley's patent application mentions other devices already on the market of a similar design, so it would not be accurate to name him or any other individual as the father of the paper clip. A Norwegian, John Vaaler, is often credited with inventing the paper clip in 1899. His patent application included several possible paper clip shapes, including one that is similar to the modern Gem clip. Because of Vaaler, the paper clip became a symbol of Norwegian nationalism during World War II. There is even a 23 ft (7 m) high statue of a paper clip in Norway. It was set up to commemorate the solidarity the Norwegians represented against the Nazis by pinning paper clips on their lapels.
A Massachusetts inventor, Cornelius Brosnan, received a patent for a paper clip design in 1900. Again, his application spoke of the product as an improvement over other paper clips already in existence. His clip was marketed as the Konaclip. The Konaclip was an oval loop of wire with an inner arm terminating in a rounded eye. At least these three clips, the Schooley, the Vaaler, and the Brosnan designs, existed by the turn of the century. In 1899 a Connecticut inventor, William Middlebrook, applied for a patent for a machine to make paper clips. Middlebrook's patent application was not for making any particular type of clip, but the one pictured on the application's illustration looked like the archetypal Gem. Gem clips were imported to the United States from England by at least 1907. The Gem was advertised as a fine English product, superior to all others. Though paper clips of differing designs continued to be made for several years, by about the mid-1930s, the Gem had become the most commonly used.
Raw Materials
Paper clips are generally made from galvanized steel wire. The wire diameter depends on what size and quality clips are being made from it. Paper clips can be made from light, cheap steel, or from better quality steel, depending on the manufacturer. The material used, however, has to fall within certain physical parameters to make satisfactory paper clips.
Design
The Gem clip is often held up as a paragon of modern design. It is simple, elegant, and surpassingly functional. Yet leaving the iconic shape aside, a paper clip designer must consider a host of mechanical and engineering questions. The material used to make a paper clip must possess certain properties. The wire needs to be stiff enough to hold its shape in use, but not so stiff that it is difficult to open. Engineers also consider a quality called yield stress when designing a paper clip. Yield stress is the amount of stress needed to permanently reshape the wire. If the wire has too low yield stress, it will stay bent open and not hold the papers tightly. Engineers also must consider the cost effectiveness of the material used. Using a cheaper, thinner wire may save the manufacturer money. Yet the material must also perform well in the manufacturing process, not leaving sharp burrs at the cut ends and resisting cracking or breaking. The material used also should be non-corrosive. The finished appearance of the clip is also a design consideration. The clip can have various finishes, smooth or slightly serrated, shiny or dull, and it can be made in many different sizes. So even though the basic Gem design has survived primarily unchanged for about a hundred years, manufacturers still confront design and materials options when making new paper clips.
The Manufacturing
Process
The manufacturing process for paper clips is fairly simple, using a specialized wire forming machine. Moreover, the process has not changed much since the 1930s.
Quality Control
Quality control is not a particularly important issue in paper clip manufacturing. Visual inspection of the product is enough to identify a problem with the process. No special tests are needed. The manufacturing equipment must be maintained in order to work properly. Some machines still in use today in the United States were built in the 1930s or even earlier. Trained workers check the equipment for wear and defects that might affect the quality of the finished clips.
By products/Waste
Though paper clips are re-usable, many are thrown away. Some office paper recyclers ask that paper clips be removed before paper is put in recycling bins. Some recyclers use metal detecting equipment that can separate out staples and paper clips, so this material can be recycled separately. One paper clip industry study estimated that the vast percentage of paper clips were never used as intended—to hold paper—but were bent and destroyed by people, used as cleaning or prying instruments, etc. Since paper clips are inexpensive, both to manufacture and to buy as a retail item, most are not re-used or recycled but simply thrown away.
The Future
The Gem clip has held sway against other contenders in paper clip design for a very long time. All-plastic paper clips came on the market in the 1950s, to some success, followed by plastic-coated clips. In the 1990s a Pennsylvania company began marketing what looks like essentially a giant Gem clip, which can hold more than one hundred sheets of paper at one time. None of these developments differs markedly from the turn-of-the-century design consumers are so familiar with. This leads to the question of whether the Gem clip is already a perfect design, thus leaving no room for improvement.

Paper clip |
A paper clip (or sometimes paperclip) is an instrument used to hold sheets of paper together, usually made of steel wire bent to a looped shape. Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire. Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper. When a moderate number of sheets are inserted between the two "tongues" of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together. Too many sheets will cause the elastic limit of the material to be exceeded, resulting in permanent deformation.

Paper clips usually have an oblong shape with straight sides, but may also be triangular or circular, or have more elaborate shapes. The most common material is steel or some other metal, but moulded plastic is also used. Some other kinds of paper clip use a two-piece clamping system. Recent innovations include multi-colored plastic-coated paper clips and spring-fastened binder clips.
According to the Early Office Museum, the first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay, in 1867. This clip was originally intended primarily for attaching tickets to fabric, although the patent recognized that it could be used to attach papers together.[1] Fay received U.S. patent 64,088 on April 23, 1867. Although functional and practical, Fay's design along with the 50 other designs patented prior to 1899 are not considered reminiscent of the modern paperclip design known today.[2] Another notable paper clip design was also patented in the United States by Erlman J. Wright in 1877. This clip was advertised at that time for use in fastening newspapers.[1]
The most common type of wire paper clip still in use, the Gem paper clip, was never patented, but it was most likely in production in Britain already in the early 1870s by "The Gem Manufacturing Company", according to the American expert on technological innovations, Professor Henry J. Petroski.[3] He refers to an 1883 article about "Gem Paper-Fasteners", praising them for being "better than ordinary pins" for "binding together papers on the same subject, a bundle of letters, or pages of a manuscript".[4] Since the 1883 article had no illustration of this early "Gem", it may have been different from modern paper clips of that name. The earliest documentation of its existence is an advertisement for "Gem Paper Clips" published by Cushman & Denison, 172 9th Avenue, New York City, in The Book-Keeper, August 1894, p. 6.[5] In 1904 Cushman & Denison registered a trade mark for the "Gem" name in connection with paper clips. The announcement stated that it had been used since March 1, 1892, which may have been the time of its introduction in the United States.[5] Paper clips are still sometimes called "Gem clips", and in Swedish the word for any paper clip is "gem".
Definite proof that the modern type of paper clip was well known in 1899 at the latest, is the patent granted to William Middlebrook of Waterbury, Connecticut on April 27 of that year for a "Machine for making wire paper clips." The drawing clearly shows that the product is a perfect clip of the Gem type.[6][7] The fact that Middlebrook did not mention it by name, suggests that it was already well known at the time. Since then countless variations on the same theme have been patented. Some have pointed instead of rounded ends, some have the end of one loop bent slightly to make it easier to insert sheets of paper, and some have wires with undulations or barbs to get a better grip. In addition, purely aesthetic variants have been patented, clips with triangular or round shapes.[8] But the original Gem type has for more than a hundred years proved to be the most practical, and consequently by far the most popular. Its qualities—ease of use, gripping without tearing, and storing without tangling—have been difficult to improve upon.
It has been claimed,[9][10][11] though apparently without evidence, that Herbert Spencer, the originator of the term "survival of the fittest", invented the paper clip. Spencer claimed in his autobiography to have invented a "binding-pin" that was distributed by Ackermann & Company, and he shows a drawing of the pin in his Appendix I (following Appendix H). This pin looked more like a modern cotter pin than a modern paper clip, but it was designed to hold sheets of paper together. It is approximately 15 cm unfolded.
A Norwegian, Johan Vaaler (1866–1910), has erroneously been identified as the inventor of the paper clip. He was granted patents in Germany[12] and in the United States[13] (1901) for a paper clip of similar design, but less functional and practical, because it lacked the last turn of the wire. Vaaler probably did not know that a better product was already on the market, although not yet in Norway. His version was never manufactured and never marketed, because the superior Gem was already available.
Long after Vaaler's death his countrymen created a national myth based on the false assumption that the paper clip was invented by an unrecognised Norwegian genius. Norwegian dictionaries since the 1950s have mentioned Vaaler as the inventor of the paper clip,[14] and that myth later found its way into international dictionaries and much of the international literature on paper clips.
Vaaler probably succeeded in having his design patented abroad, despite the previous existence of more useful paper clips, because patent authorities at that time were quite liberal and rewarded any marginal modification of existing inventions.[15] Johan Vaaler began working for Alfred J. Bryns Patentkontor in Kristiania in 1892 and was later promoted to office manager, a position he held until his death.[16] As the employee of a patent office, he could easily have obtained a patent in Norway. His reasons for applying abroad are not known, but it is possible that he had an exaggerated confidence in his own invention and wanted to secure the commercial rights internationally. Also, he may have been aware that a Norwegian manufacturer would find it difficult to introduce a new invention abroad, starting from the small home market. Vaaler's patents expired quietly, while the "Gem" was used worldwide, also in his own country. The failure of his design was obvious — it was too impractical. Without the two full loops of the fully developed paper clip, it was difficult to insert sheets of paper into his clip. One could manipulate the end of the inner wire so that it could receive the sheet, but the outer wire was a dead end because it could not exploit the torsion principle. The clip would instead stand out like a keel, perpendicular to the sheet of paper. The impracticality of Vaaler's design may easily be demonstrated by cutting off the last outer loop and one long side from a regular Gem clip.
The originator of the Norwegian paper clip myth was an engineer of the national patent agency who visited Germany in the 1920s to register Norwegian patents in that country. He came across Vaaler's patent, but failed to detect that it was not the same as the then-common Gem-type clip.[17] In the report of the first fifty years of the patent agency, he wrote an article in which he proclaimed Vaaler to be the inventor of the common paper clip.[18] This piece of information found its way into some Norwegian encyclopedias after World War II.
Events of that war contributed greatly to the mythical status of the paper clip. Patriots wore them in their lapels as a symbol of resistance to the German occupiers and local Nazi authorities when other signs of resistance, such as flag pins or pins showing the cipher of the exiled King Haakon VII of Norway were forbidden. Those wearing them did not yet see them as national symbols, as the myth of their Norwegian origin was not commonly known at the time. The clips were meant to denote solidarity and unity ("we are bound together"). The wearing of paper clips was soon prohibited, and people wearing them could risk severe punishment.[19]
The leading Norwegian encyclopedia mentioned the role of the paper clip as a symbol of resistance in a supplementary volume in 1952, but did not yet proclaim it a Norwegian invention.[20] That information was added in later editions. According to the 1974 edition, the idea of using the paper clip to denote resistance originated in France. A clip worn on a lapel or front pocket could be seen as "deux gaules" (two posts or poles) and be interpreted as a reference to the leader of the French Resistance, General Charles de Gaulle.[21]
The post-war years saw a widespread consolidation of the paper clip as a national symbol. Authors of books and articles on the history of Norwegian technology eagerly seized it to make a thin story more substantial. They chose to overlook the fact that Vaaler's clip was not the same as the fully developed Gem-type clip.[22] In 1989 a giant paper clip, almost 7 meters high, was erected on the campus of a commercial college near Oslo in honour of Vaaler, ninety years after his invention was patented. But this monument shows a Gem-type clip, not the one patented by Vaaler. The celebration of the alleged Norwegian origin of the paper clip culminated in 1999, one hundred years after Vaaler submitted his application for a German patent. A commemorative stamp was issued that year, the first in a series to draw attention to Norwegian inventiveness. The background shows a facsimile of the German "Patentschrift". However, the figure in the foreground is not the paper clip depicted on that document, but the much better-known "Gem". In 2005, the national biographical encyclopedia of Norway (Norsk biografisk leksikon) published the biography of Johan Vaaler, stating he was the inventor of the paper clip.[23]
The Paper Clips Project is celebrated in the 2004 documentary, "Paper Clips" (film), Paper Clips Project
Johan Vaaler's fame as the paper clip inventor has spread worldwide, especially in the United States. When eighth-graders at Whitwell Middle School in Tennessee were to learn about the murder of six million Jews during the Holocaust, one teacher had the idea of illustrating that mind-boggling number by collecting as many small and cheap objects—this was called the Paper Clips Project. According to one website, the paper clip was chosen "after they learned (that) Norwegians wore them on their clothes to show support for Jews during World War II".[24] Another site elaborates this story even further: "That symbol of resistance originally honored Johann Vaaler, the Norwegian Jew who invented the paper clip".[25] Both of these statements are false. Vaaler was not a Jew,[26] he did not invent the common paper clip, and Norwegians who wore them did not do so to protest the tragic fate of the Jews, but to show national concord and solidarity, and opposition to the German occupation and local Nazi authorities.[19] But the project was a success — far more than the required 6 million clips were collected.
During promotion of the film that documents the middle school project, the film's promoters contacted and partnered with Baumgarten's Office Products in Atlanta, Georgia. Baumgarten's is the company that manufactures Plastiklips and other fastening devices; they constructed displays made of green plastic paper clips shaped into the Star of David to assist with the film's promotion at theaters around the United States. Hans Baumgarten, Baumgarten's treasurer and his family of Jewish descent, left Nazi Germany, avoiding death camps.
Baumgarten's Plastiklip was invented by the German Kurt Lorber, who has been a partner with Baumgarten's since World War II.
Paper Clip Project was expanded by Wayne McIntyre in Canada and by Miljenko Hajdarovic in Croatia.
Wire is versatile in its nature. Thus a paper clip is a useful accessory in many kinds of mechanical work including computer work: the metal wire can be unfolded with a little force. Several devices call for a very thin rod to push a recessed button which the user might only rarely need. This is seen on most CD-ROM drives as an "emergency eject" should the power fail; also on early floppy disk drives (including the early Macintosh). Both 1st generation iPhones and the iPhone 3G require a paper clip to eject the SIM card and some Palm PDAs advise the use of a paper clip to reset the device. The track ball can be removed from early Logitech pointing devices using a paper clip as the key to the bezel. A paper clip bent into a "U" can be used to start an ATX PSU without connecting it to a motherboard (connect the green to a black on the motherboard header). One or more paper clips can make a loopback device for a RS232 interface (or indeed many interfaces). A paper clip could be installed in a Commodore 1541 disk-drive as a flexible head-stop. Paper clips have been used (unsafely) to replace fuses.
Paper clips can be bent into a crude but sometimes effective lock picking device. Some types of handcuffs can be unfastened using paper clips. There are two approaches. The first one is to unfold the clip in a line and then the end to be twisted in right angle trying to imitate a key and using it to lift the lock fixator. The second approach, which is more feasible but needs some practice, is to use the semi-unfolded clip kink for lifting when the clip is inserted through the hole where the handcuffs are closed.[citation needed]
Paper clips can be worn as bracelets and rings, thus ensuring they can be found for their other uses.
