No, sewing machines do not all use the same needles for their operations. Different types of sewing machines require different types and sizes of needles to properly sew different fabrics and achieve different results.
Singer sewing machines are the same as Pfaff machines just as a Hummer vehicle is the same as a GMC vehicle. Pfaff owns Singer.
No, sewing machine needles are not all the same in terms of compatibility with different types of fabric and sewing projects. Different needles are designed for specific fabrics and projects, such as heavy-duty needles for thick fabrics and fine needles for delicate fabrics. It is important to use the correct needle for the fabric and project to achieve the best results.
In the same way they are today
Same thing used today. Mostly small electric motors.
Sewing machines come in all shapes sizes and colours. Most machines look alike and have the same features.
Sewing machines are generally the same,it is best to start with an older machine to lean the basics.
A serger (overlock) sewing machine uses up to four threads and has a special trimming blade. It is designed for one main job: it sews, trims and overcasts the seam at the same time. Its function is specialized, but it can really speed up sewing and gives the finished item a professional look. A serger is a great machine for sewing stretch fabrics. A home sewing machine is designed to do a wider variety of tasks. It will generally have more stitches, plus presser feet and attachments to sew zippers, buttonholes, do machine quilting, etc. There is usually an overlock stitch on a home sewing machine, but you can't sew the seam, overlock and trim all in one pass. Lots of sewers have one (or more!) of each.
Have the instruction book but does not mention so I have the machine and I would say same size as the singer but are metal OK ( bobbin ) Most Kenmore sewing machines (including this one) take class 15 bobbins which you can find at Joann's, Walmart, and most places that deal in sewing machines. They come in either plastic or metal.
The sewing machines used to make clothing are the same in France as the ones used everywhere else on the face of the planet.
My puppy has not had its needles is it possible for the puppy to be in the same room with a dog that has had all its needles and boosters done.
To answer your question with the annoying word "depends" is an understatement. All kinds of sewing machines do an amazing array of things, and some, like mine, are like the original. In the beginning, sewing machines made only one kind of stitch. This is called the running stitch, or straight stitch, because the stitches run in one direction, one stitch in front of another. For a detailed description of how this basic stitch works, see "www.Howstuffworks.com/sewing-machine". All machine stitches are based on the same formula, but the variety of stitches now available on the most sophisticated of machines are made possible by the "feed dog". That is the little teeth that move the fabric around, and the movable (zig-zag) needle, which can stitch in a side to side motion. Some of the newer machines come with a set of "cams" that are put into the machines which control the pattern. Now, you can even purchase machines that can be programmed by means of an internal computer to provide actual pictures stitched onto your fabric. For more information, including a history of sewing machines, see the excellent Wikipedia article, wikipedia.org.wiki/Sewing_machine
They are called circular needles and they are used in exactly the same way as straight needles.
