TC/CH20 is the Blind Hemming Guide Package which Prevents Misalignments During Blind Hemming Operations.

Plyshifting on the cross seam sections is a common cause of misalignments during the blind hemming operations.

This package detects the cross seam sections by its sensor and automatically slides the guide to prevent fabric misalignments. The guide slides back once reaching for the predetermined stitch count.

Just turning the TC lever, you may change thread tension as appropriate according to sewing applications such as blind hemming or general seaming.
