Feeds thread from spool to needle?
The thread moves from the spool through the needle to make stitches on a sewing machine. The thread take-up lever is what feeds the thread from the spool to the needle as it moves up and down.
What is a spool case?
a spoolcase is something that you use in sewing or when you sew you put the spool into a spoolcase but you must make sure the spool is filled up with thread then you can start sewing only if you have a long piece of thread in the spool!!
How many cocoons are needed to make 1 kg of raw silk?
Silk is made from the cocoons of silkworms. It takes 5500 cocoons to make just 2.2 lbs., or 1 kilogram, of silk.
What is a sewing bobbin?
A sewing bobbin is a small spool of thread that goes underneath the needle and sewing platform. It provides the lower thread for the sewing machine. Different models of machines use different bobbins, but most machines require you to create the bobbin yourself.If you'd like to see a picture of a typical sewing machine bobbin, visit the "related link" below.If you look at a diagram of the way a sewing machine works, you can see that when the needle goes down to the bobbin, the bobbin thread is pushed around the upper thread, and that is how the two pieces of fabric are joined together.The upper thread goes along the top of the seam, and the bobbin thread goes along the bottom of the seam.
Why are silk cocoons boiled?
Silkworm cocoons are placed in boiling water to make the one long continuous thread separate from it.
Why is a cocoon that produces a live silkmoth useless for making silk clothes?
The silk that is made into the cloth is the thread that the silkmoth caterpillar spins to make its cocoon. Thus the cocoons are boiled to kill the pupa and free the silk thread.
Is silk from the silkworms cocoon used to make anything?
Yes it is! Silk from silkworm cocoons is extracted to be used for manufacturing of many types of clothing; meaning, that the silky clothings you are wearing are actually made of many threads of silk that were extracted from many silkworm cocoons. In fact, only one silkworm cocoon contains a single continuous silk thread that can reach about 3600 feet in length! This method of manufacturing originated in China, where the first silk keel was invented and there are different farming methods in different countries. The process of extraction in Chinese farms involves heating the cocoons in an oven in order to kill the silkworm inside the cocoon, and then soaking the cocoons in water in order to identify the end of the silk thread. Once theyre soaked, the silk is extracted from the cocoons using multiple threads from several cocoons to form a single silk thread (since one thread of silk from one cocoon is too thin). Hope that helps:)
Do butterflies make crysalisis?
Yes, Butterflies do make crysalisis. Moths make cocoons. Some butterflies make cocoons too. Pee girl
Do butterflies make coccon?
Bu6terflies make chrysalises rather than cocoons. Moths make cocoons out of silk and butterflies make chrysalises during their molting.
How do you thread Elna 1500 sewing machine?
First, raise the presser foot lever and turn the flywheel towards you to raise the thread take-up lever to its highest point. Next,, place your spool of thread on the horizontal post and hold in place with the spool cap. You know that little nick in the spool where you tuck your thread so the spool won't unravel? Make sure that nick is pointing to the right. Now draw your thread to the left and "click" it into the little silver loop. A 1" oval thread guide sits to the left of that silver loop; draw your thread around the left of the thread guide. Now you're going to loop your thread through the tension discs. You'll see two "cracks" in your machine. First run your thread DOWN through the RIGHT crack, then immediately UP through the LEFT crack. At the top of the LEFT crack is your silver thread take-up lever. This is probably the trickiest part of threading your machine because the lever is always kind of inside the machine. But you can do it! Pass your thread from RIGHT to LEFT through the back of the loop at the top of the silver lever. Whew! We're almost there. Now draw your thread right back down the same crack you pulled it up before. You now have two stationary guides above your needle. Pass it through the thick silver guide and then through the thin silver guide. Both of these moves are kind of a left-to-right motion. Now thread your needle from FRONT to BACK. You're done -- well, except for the bobbin. Hold your bobbin spool above the bobbin case so that it looks like a letter "P" Draw the bobblin thread from RIGHT to LEFT through the small crack in the silver part of the bobbin case, then pull the thread straight toward the back of the machine. Now turn your flywheel one revolution toward you so that your upper thread picks up the bobbin thread. Now close your bobbin cover, and SEW! Congratulations! You did it!
Describe the stitching mechanism in a sewing machine?
Sewing machines use two spools of thread, unlike hand sewing, which uses one fixed-length piece. You can emulate the machine-stitching process by hand. Imagine you have a needle through which the thread from a large spool is threaded and a second, smaller spool of thread. Push the needle eye-end first through the fabric from above. Pull the loop of thread on the back side bigger, until you can pass the little spool through the loop. Now, from above pull the top thread tight to close the loop back up again. That is all a sewing machine does. The arm at the front that moves up and down a lot supplies the slack to make the bottom loop big enough, and then moves back up to take up all the slack, and to pull a tiny bit more thread off of the top spool through the tensioning mechanism. The hard-to-visualise bit is at the bottom, where the bottom spool is passed through the loop. The key to understanding it is that the spool and whatever carrier it is in "floats" in a space rather than actually being fastened to the rest of the mechanism. There is a gap round it on all sides (though sometimes an oddly shaped one) which allows the loop of top-thread to pass all the way round it. Typically a hook of some sort grabs the top-loop near the needle eye, and pulls the loop bigger while passing that loop round the outside of the bottom spool assembly. If you operate the machine by hand with the covers off you should be able to see this happening.
Can earthworms loose their clitellum?
Maybe but they can't make cocoons
