ABSTRACT:
A sewing machine with a drive for a work clamp comprises two slides movable relative to each other, one carrying the work clamp and the other carrying two tail wheels and an endless belt trained thereabout. Two stepping motors which can selectively be run in the same or in opposite directions are engaged each with a respective one of the belt strands, so that with the motors running in opposite directions, the two slides move in the lengthwise direction, while with a run in the same directions, only the slide directly carrying the work clamp is moved, namely transversely. In another embodiment, the slide directly carrying the work clamp is non-rotatably connected to one of the tail wheels.
