RUBBER THREAD SEWING MACHINE

摘要

PROBLEM TO BE SOLVED: To reliably obtain a sewn article having a well-finished elastic expandable portion by sewing rubber thread with a plurality of rubber threads equally stretched. SOLUTION: A rubber thread sewing machine has a rubber thread intermittent delivery mechanism 30 capable of delivering a plurality of rubber thread 7 by elastically pinching and relatively rotating the plurality of rubber threads 7 by a driving roller 34 that can be intermittently driven and rotated only in one direction by a matched tensile force and a following roller 45 elastically butting the periphery thereof between a thread handling area 9B arranged before the direction of progress of sewing rather than a plurality of sewing needles 4 arranged side by side in the direction perpendicular to the direction of progress of sewing and introducing and guiding the plurality of rubber threads 7 into between the needle plate 3 and a presser bar 9 correspondingly to the sewing needles 4 along the top face of a needle plate 3, and the supply section of the plurality of rubber threads 7.
