Abstract:
A method for manufacturing an invisible trademark zipper, comprising:(1) transferring a continued yard strip printed or weaved thereon with complementary halves of a pattern, a character, or a mark facing down into a weaving machine; (2) synchronizing two zipper teeth by passing the two zipper teeth through a teeth driving device by which tooth-by-tooth feeding and consistent teeth pitch can be carried out, thereafter transferring the two zipper teeth together with the continued yard strip into the weaving machine; (3) sewing the two zipper teeth on predetermined positions at two sides of a longitudinal central line of the continued yard strip near the complementary halves of a pattern, a character, or a mark by using two sets of needles; (4) using a cutting device to cut the continued yard strip into two symmetric pieces along the longitudinal central line of the continued yard strip, thereby forming two zipper strips having respective zipper teeth and foldable fringes; and (5) folding the two foldable fringes of the two zipper strips; wherein by folding the two zipper strips and the use of a pull tab, the zipper teeth are engaged with each other to completely present the pattern, character, or mark on the two zipper strips.
