ABSTRACT:
A threading mechanism where a thread catcher hook is reciprocated between two needles by a movable means. Although the two juxtaposed needles are separated horizontally and vertically, position aligning means places the hook opposite either needle eye, thereby facilitating threading both needles and greatly improving sewing efficiency.
