Patent number: 10258114Abstract: Stringers without fastener tape have continuous fastener elements and have element fixing members wherein the fastener elements are sewn together by a sewing thread. The element fixing members are inserted between upper and lower leg sections of the fastener elements. The sewing thread comes in contact with and straddles the upper and lower leg sections of each fastener element and pierces the element fixing members between the fastener elements. As a result of such stringers without fastener tape, the fastener elements can be held and the weight and cost of an article with a slide fastener can be reduced.Type: GrantFiled: December 16, 2013Date of Patent: April 16, 2019Assignee: YKK CorporationInventors: Yoshiyuki Sho, Makoto Saito
