ABSTRACT:
A zig zag sewing machine, wherein a needle bar having a basting position beyond its zig zagging range, is provided with a presser foot having therein an elongate opening which is defined to permit one needle of a twin needle device to pass therethrough without striking the foot upon descent of the needle bar of the machine from a basting position, and which has a beveled edge to interfere at one end of the opening with the other needle and deflect such other needle so that it can pass through the opening.
