ABSTRACT:
A two-needle sewing machine includes a machine casing having a sewing head mounting the needles, a work support plate, and a ripping knife supported in the sewing head and working between the needles to form an elongated slot of a braid opening in a cut garment piece. A supporting bar is guided in the machine casing for longitudinal displacement perpendicular to the work support plate, and is rotatable into different angular positions. A single angular cross-section cutting knife is mounted on the supporting bar and serves as a tool for making diverging corner cuts at the opposite ends of the elongated slot. Air-operated piston-cylinder actuators are provided to rotate the supporting bar between two positions spaced angularly by 180.degree., and to displace the supporting bar longitudinally to effect the diverging corner cuts. The sewing head mounts a sliding foot arrangement for moving the work in a direction opposite to the normal work feeding direction.
