Presser Wheel?

Hi!  Anyone know why you’d want a presser wheel vs a foot…and if you can get them for a Techsew 5100?

Presser for wheels are generally used on bottom feed machines like post bed machines. An example would be the Techsew 810. They will not work on a walking foot or a compound feed machine, the Techsew 5100.

The only purpose of a roller foot is to reduce the drag on the top layer of a stack of material that's being pulled on the bottom by feed dogs with teeth. If the material is grabby, a flat presser foot will fight against the feeding and cause uneven stitches. They are often used on machines that are going to sew patterns on shoes and boots, or on machines that sew hats. The roller is adjustable to the left and right. The usual practice is to position the bottom inside edge so it just clears the needle on the up and down stroke. This closeness ensures that the material doesn't lift with the ascending, threaded needle, which would cause skipped stitches. A roller foot gives 100% visibility of the needle in three dimensions.

As KGG already mentioned, they are not used on walking foot machines, which have not two, but three bars extending down. They are meant for bottom feed machines that only have one presser foot bar. Walking foot machines already solve the problem of drag with their motion sequence.
