Abstract
A sewing machine, particularly a multi-needle sewing machine, includes at least one sewing arrangement which includes a reciprocating needle mounted on a needle holding arrangement and a gripper mounted on a gripper holding arrangement for angular displacement along a displacement plane and operative for engaging a thread delivered by the needle through the material being sewn to a predetermined region beyond the material. As the material is advanced, especially transversely of the displacement plane, during the sewing stroke of the needle, it acts on the needle and deviates the same from its initial course. To avoid malfunctions, at least one of the holding arrangements is mounted on the support for movement at least transversely of the displacement plane and parallel to the sewing plane of the material, and such one holding means is displaced by an appropriate moving arrangement in dependence on the extent of the deviation of the needle in such a manner that the distance between the needle and the displacement plane of the gripper is maintained substantially constant during the sewing stroke of the needle.
