Abstract

This invention provides a cylinder type valance stitch sewing machine where simplification of structure and miniaturization can be realized in addition to following belt drive and which is suitable for valance flat sewing with cylinder type multiple needles. The cylinder type valance stitch sewing machine is provided with: a sewing machine bed 1; a nearly L-shaped arm 2 formed projecting on the side of the upper surface of the bed 1; and a cylinder 3 formed projecting forward so as to oppose the lower side of an arm head part 2b from the front side face of the sewing machine bed 1 so as to feed cloth backward from the tip of the cylinder. A drive shaft 4 arranged in the bed 1 is belt-driven with a driven shaft 6 arranged in the arm head part 2b. The tip side of the arm head part 2b is provided with: a needle bar drive mechanism 14 which changes the rotation of the driven shaft to the vertical movement of a needle bar 13 with a plurality of sewing machine needles 12 fitted to its lower end to drive the needle bar; and a spreader drive mechanism 17 which changes the rotation of the driven shaft to the rocking movement of a spreader 16 for valance threads fitted to the lower end of a spreader rotary shaft 15 to drive the spreader.

Description

technical field [0001] The present invention relates to a sewing machine with a cylindrical cylinder, and more specifically, it is used to feed cloth in the longitudinal direction of a cylindrical cylinder to form a decorative cloth seam above a curtain such as a flat chain seam. Type of sewing machine for fabric seaming of decorative cloth above the curtain. Background technique [0002] Conventionally, there is a belt-driven sewing machine in which a power transmission belt is wound between a driving pulley rotated by a sewing machine motor and a driven pulley for vertically moving the needle bar (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 63-11194. [0004] However, the above-mentioned belt-driven sewing machine is applicable to a sewing machine for flat sewing with one needle, but it is difficult to adopt the above-mentioned belt-driven sewing machine on a sewing machine with a more complicated structu...
