A folding stamp for folding sewing parts which are to be attached to a main sewing part, in a sewing system for making pockets in articles of clothing. The additional sewing parts, such as flaps or pocket-bag blanks, can be fed manually. This folding stamp has a fastening unit arranged on an upwardly and rearwardly extending extension formed on a vertical web. The fastening unit thereby extends above a resting surface on top of the web and in the direction toward the rear end of the folding stamp. The folding stamp is thereby arcuate or C-shaped in longitudinal cross-section, which gives it a compact construction and gives the operator an unimpeded view of the region in which he must feed the additional sewing parts.

Folding stamp for a sewing machine

A sewing machine, having a device for centrally cutting a piping strip at both of its ends. At least one knife is arranged in a piping strip gripper between the parallel rows of oblique gripping needles. Before the start of the sewing process, a piping strip which has been placed at a predetermined position on a resting plate is held clamped between said plate and the gripper, which is lowered onto the resting plate. By actuation of the knife by an external force such as a pressure fluid, a blade of the knife penetrates into the piping strip and, by horizontal displacement of the knife, the piping strip is incised centrally at its end. Preferably there is a blade for each end of the piping strip.
