ABSTRACT:
An apparatus for terminating the last stitch at a predetermined point including two workpiece-end detectors, one working to reduce the stitching speed and the other working to terminate the last stitch at the predetermined point with reduced speed. Where the number of stitches (D) to be conducted at the reduced speed exceeds number of stitches (R) necessary to reduce the speed, stitching without reducing speed continues and the number of stitches is operated as (D-R), and then the speed is reduced. Thus, stitching speed is increased. The above processes are automatically conducted through a CPU (Central Processing Unit) by input of the necessary data, namely, the original stitch pitch (P), the margin distance (a), the number of stitches (R) necessary to reduce speed, etc.
