it takes the thread up and down so you can keep sewing
The take up lever is used in threading the sewing machine and to keep the thread tension at the proper level. If the take up lever is threaded improperly, the thread will knot up and jam in the machine.
it takes the thread up and down so you can keep sewing
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.
sometimes
Take the thread through the first thread guide which is on the right, then through the needle guide notch. Wind the thread around the tension dial and pull up to the left of the dial. Pull the thread into the thread guide at the bottom. Take the thread from front to back through the needle eye.
pls
Thread guides lead the thread in this order: Thread Spool to Tension Discs to Take-Up Lever to Needle. A machine is threaded with the take-up lever in its highest position and the presser bar lifted. Generally, the thread guides provide a path that keeps the thread from crossing over itself. From the spool, any thread guides mounted on the top cover are first, back to front. On the face plate (front of machine) any thread guides that sit to the right of the tension discs are threaded before inserting thread around & between the discs. If there be any thread guide that is BOTH to the left of the tension discs AND right of the take up lever, the thread would go there next. My fairly typical Japanese Zigzag Machine does not have a thread guide between the tension discs and the take-up lever, but if there were one, I would call it the "Tension to Take-Up Lever Thread Guide." From there the thread passes right-to left through the hole of the take up lever, and then down through all thread guides mounted to the left of the take-up lever. Lastly, the thread goes down through a needle clamp thread guide and through the eye of the needle. Not a short answer, but I hope it addresses your question.

The purpose of the check spring is to maintain tension on the thread as the thread take up arm returns to the top of the stroke pulling the thread back out of the cloth.The take-up arm follows the needle. As the needle leaves the cloth, the friction between the thread and the cloth forms a loop that the hook inside the machine catches, pulls around the lower/bobbin thread forming the locked stitch. As the take up arm returns to the top of the stroke the thread between the tensioner and the take up arm becomes slack. The check spring pulls on this slack to keep the thread taut.Proper stitches can not be formed if the check spring is not set with sufficient "snap-back" or tension on the spring. Setting the "snap-back" is by feel. Adjust it from loose to tighter to get good stitches. It is a three way balance between the upper thread tensioner, the check spring and the bobbin tension.
You forgot to hold the thread ends until you made a stitch or two and the motion of the take up leaver unthreaded the needle.
