ABSTRACT:
A double-needle chuck assembly for a sewing machine is provided with a knife that is moveable from a position on one side of the needles to a position on the other side. This enables a closed slit, as might be required for a pocket of a garment, to be produced with stitching on both sides and at the ends thereof without reversing the direction of movement of the fabric or using a separate step in a production line. The knife is mounted on a rod which engages a slot extending between the needles, with the rod being securable in either of the two positions by a detent mechanism. Movement of the rod to change positions of the knife may be performed manually or by a pneumatic actuator.
