Abstract
A thread taking-up tool is attached to a needle bar sticking out of a sewing machine head, and its leading end has a plurality of thread holes. The thread holes of the thread taking-up tool are arranged in the lateral direction. A thread handling body has a cam face in the vertical direction. Needle threads from a tension device to needles are controlled by the vertical motion of the thread taking-up tool and the action of the cam face of the thread handling body. When the needles ascend from the lowest position, an endless hook attached to the thread taking-up tool is engaged with the left needle thread between the cam face lower end and the thread hole of the thread taking-up tool. Each thread is handled in with the left needle thread staying at the cam face lower end, so that the needle thread loop at the remotest end is absorbed surely.
