ABSTRACT:
A needle guard for an industrial zigzag sewing machine designed to provide support for the sewing needle in all lateral positions of the needle. The needle guard provides a lead in surface to return an already deflected needle to a supporting surface which in a first embodiment lies in a plane immediately adjacent a plane including the circular path traversed by the loop seizing beak. In a second embodiment a supporting surface is provided which compensates for the point of contact variations due to the cone pointed end of the sewing needle.
