Blind stitch - sewing machine - with electronic control to determine stitch count

摘要

Stitch count is applied by a setting control and scale for the switches operated by the foot pedal to operate the fabric clamp to establish the depth of stitching, and then to execute the set number of stitches, with electronic control for the self-braking motor. A rotary magnet is used with a linkage to control the fabric clamping mechanism.
