LT and LT are looper threads.

Claims

[Claim for Utility Model Registration] An integrated louver whose base end is attached to the end of the looper shaft, through which the looper thread LT is inserted near the tip 2 of the open end, and which forms a chainstitch stitch in cooperation with the sewing machine needle. 1, a first notch 3 formed by cutting back and forth along the cloth feeding direction of the sewing machine near the tip 2 of the louver unit 1;
and, following the notch 3, a second notch 4 is formed by cutting out the back surface of the louver unit 1 on the sewing machine cloth feed side;
' A concave groove 5 is provided toward the proximal end of the louver unit 1 from the first notch 3, and a deep hole 6 is provided on the proximal side of the louver unit 1, and a hook-shaped proximal end is provided. The hook-shaped tip 7a is fitted into the deep hole 6, and the proximal end 7b following it is inserted into the concave groove 5 and fixed, so that the open end side or the tip of the louver body 1 A second notch 4 is formed, which extends so as to straddle the first notch 3 and whose tip is curved toward the proximal end of the louver body 1.
a wire-like thread hanging body 7 located inside and arranged to have a gap t between it and the bottom 4a of the second notch 4 to allow the looper thread LT to pass therethrough; The curved portion 7C of the hanging body 7 is arranged to intersect with the edge 3a of the first notch 3 at a position slightly closer to the proximal end than the open end of the looper integral 1 of the first notch 3. Therefore, the louver is integrated so that the looper thread LT is hung on the wire-like thread hook 7 through the gap t between the wire-like thread hook 7 and the second notch 4.
