Abstract (en)
[origin: WO2013022115A1] A needle plate base (11) in a multi-thread chain stitch sewing machine with a seam ravel preventing apparatus is divided into a left needle plate base ( 11L) for attaching a needle plate ( P) thereto and supporting a swinging support shaft (30) of a thread hanging hook (3); and a right needle plate base (11R) for fixedly supporting a stopper member (4) and a thread handling air cylinder (32) and a stopper air cylinder (42). The right needle plate base(llR) is fastened to a sewing machine bed (B). The left needle plate base (11L) is fastenably and unfastenably fastened to an upper surface of the bed(B) via screw members (102). Adj ustment of stitch performation, and maintenance, e.g., replacement of various kinds of components stored inside the bed, can extremely easily and simply be carried out without having much trouble and requiring labor and time, and therefore, the stitch performation and predetermined ravel preventing function can be constantly surely reproduced.
