Abstract

A device for cutting and turning a piped opening in a cloth workpiece which includes a main piece of cloth and a cloth strip sewed to it. The workpiece has a slit, and corner cuts are formed at the slit ends by corner knives with the workpiece lying on a support plate. Turning tools are introduced into the slit at positions located spaced from the corner cuts. The turning tools are then moved apart toward positions located closer to the corner cuts and thereupon lowered, so as to turn the piped opening. Inserting devices may be provided for initially pushing at least part of the workpiece into the slit before being engaged by the turning tools. An orienting device furthermore may orient the workpiece at an acute angle or perpendicular to the support plate for being engaged by the turning tools.
