Abstract
A sewing apparatus of circular rib of the invention is applied to the case of sewing a circular rib in a tape form to the end portion of a tubular cloth such as the waist portion of briefs. A first cloth end controlling device corrects the position by gripping the end portion of a tubular cloth C between a control roller 23 and a roller holder 25 so as to support an circular rib R and tubular cloth C separately at right and left side, in a front roller 1, out of plural rollers 1, 2, 3 disposed in front and rear of the needle drop point 5 of a sewing machine. A second cloth end controlling device corrects the position by gripping the end portion of the tubular cloth C between the control roller 22 and roller holder 24, so that the end portion may overlap with the circular rib R. Moreover, near the second cloth end controlling device, a rib detaching guide 4 supports only the circular rib R, and moves away to a waiting position along with approach of the sewing start portion. In this constitution, without having to stop the sewing machine temporarily, the both pieces R and C can be sewn together accurately and efficiently.
