Small, serrated metallic plates beneath the presser foot of a stitching machine, these elements work at the side of the presser foot to advance material throughout stitching. Their synchronized up-and-down and forward-and-backward movement grips the fabric and strikes it underneath the needle at a managed tempo. This exact motion is crucial for constant sew size and total stitching high quality. Take into account them analogous to the gears in a clock, steadily transferring the fingers ahead.
These important elements contribute considerably to the precision and effectivity of the stitching course of. With out their managed motion, constant sew size and straight seams can be almost not possible to attain. Moreover, differing kinds can be found, every designed for particular material varieties and stitching wants. Their invention was a pivotal development in stitching machine expertise, enabling extra automated and constant stitching, finally contributing to the mass manufacturing of textiles.
