Title: Upper thread controller in sewing machine
Inventor: AKIYAMA TATSUKIMI
IPC: D05B47/04
Filed: 1990-07-03
Abstract: PURPOSE:To always even loops supplied to a pointed tip of a shuttle and prevent the occurrence of skip stitch and thread cut by forming a thread path of an upper thread projecting from one end of a needle bar swinging stand passing through an auxiliary thread take-up lever and changing the length of the thread passing through the right and left swing positions of the needle bar swing stand. CONSTITUTION:A needle bar 1 is displaced left and right by a needle bar swing stand 3 in timing synchronized with vertical drive to lower a sewing needle 5 to positions indicated by arrows A, B. Then, an auxiliary thread take-up lever 6 of an upper thread control mechanism 11 is displaced together with the needle bar swing stand 3. While the upper thread (a) passing through both thread paths 10, 10 and a thread hole 8 in the case of the right swing A passes by the shortest distance in the straight manner, the upper thread (a) passing through both thread paths 10, 10 and the thread hole 8 in the case of the left swing B is bent into a V shape, so that the upper thread is taken in the direction of arrow D so as to lessen a loop b. Thus, by presetting the displacement of the auxiliary thread take-up lever 6, the loop (b) of the thread (a) formed for the sewing needle 5 in the position of a shuttle 13 in the cases of the right and left swings can be evened to stabilize the loop (b) supplied to a pointed tip 14 of the shuttle 13 pivoting in the direction or arrow C.
