ABSTRACT:
A thread take-up lever guard in a multi-needle sewing machine provided with a support disposed on the front surface of a head, a plurality of needle bars each having a needle attached to the lower end, and a plurality of thread take-up levers disposed to oppose the needle bars respectively and protruded from the support to be able to oscillate vertically. The thread take-up lever guard prevents a needle thread carried on a selected thread take-up lever from being caught by an adjacent thread take-up lever assuming a standing posture or is tangled with another needle thread carried on the standing thread take-up lever. The thread take-up lever guard comprises a separator disposed on the support such that every adjacent two thread take-up levers may be isolated from each other over a predetermined range of routes along which the take-up levers reciprocate. The separators are notched at positions where thread holes of the thread take-up levers are situated when the thread take-up levers are assuming predetermined standing postures.
