摘要

The machine (1) has a horizontal shuttle for trapping a loop of a needle thread formed below a needle plate (13) to form a seam when a needle (21) is moved upwardly and the needle thread is entangled with a bobbin thread. A work-piece pusher (51) has a beveled part (53) formed by cutting a corner part. The beveled part is formed in form of a curved line or sheet. An edge part of the pusher at one side of the horizontal shuttle impinges another edge part of the pusher in a feed direction on a progression side.
