ABSTRACT:
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.
