Abstract

A multi-needle sewing machine capable of preventing twisting (twinning) associated with the oversupply state of a second thread element owing to the abrupt lowering of a thread take-up am even when the vertical reciprocation speeds of the needle bar and the thread take-up are increased to raise the efficiency of sewing. A recess is formed so that the second thread element that is pulled using the through hole of the thread take-up arm while at a bottom dead center can fall into the recess, the thread is lowered abruptly and is in a oversupply state and can be deflected within the recess bounded by jump preventing faces and a beaten thread portion face, so as to make contact with the faces and prevent the thread from jumping.
