Darning and embroidery attachment
摘要:
A unitary molded darning and embroidery attachment for a sewing machine. A plastic clamping member suitable for attachment to a sewing machine presser bar, and a plastic darning and embroidery member, including a striker arm acted on by an endwise reciprocating needle bar of a sewing machine over a portion of its endwise reciprocation, are joined by a resilient member integrally molded with the clamping member and darning member. The motion imparted to a darning foot portion of the darning member by the action of the needle bar on the striker arm, which is utilized to lift the darning foot from the work material in order to allow the work fabric to be moved, is effectively isolated from the clamping member and the presser bar by the integrally molded resilient member.
