MANUFACTURE OF TACK WITH CORD

PURPOSE:To remarkably improve the productivity, while cord-fitting operation is simplified by a method in which in the state where a cord is positioned on two small pieces in parallel arranged by causing the cord to pass through the groove provided in a frame, another small piece is further superimposed thereon, and then the upper and lower small pieces are integrally welded. CONSTITUTION:A peeling mount 6, is placed in the frame 2 on a lower electrode 1. Next, the small pieces 8 enclosed with a cutting off line 7 are arranged two by two in parallel, and are made in a pair, and then after the trasparent thermoplastic sheet 9 in which said pieces are separately arranged alternately with each other left and right, has been superimposed on the peelable mount 6, the part except the small pieces is drawn out. A cord 11 is extended through the hole 4 of a cord-guiding plate 16, and is positioned on the small pieces 8 through a groove 3. The thermoplastic sheet 14 in which the small pieces 13 enclosed by the cutting off line 7 similarly to the small pieces 8 are arranged, is placed on the cord 11. The upper and lower small pieces 8, 13 are integrally welded by the upper electrode 15 of a welder, whereby the cord 11 is nipped adhesively therebetween.
