Abstract

The disclosure discloses a fastener tape, a slide fastener and a fastener tape manufacturing device. The fastener tape includes a fastener tape body and a fastener element fixed to a first side of the fastener tape body. A second side of the fastener tape body is folded toward a back side of the fastener tape body, and a bent part extending along a length direction of the fastener tape is formed after the folding. The bent part divides the fastener tape body into a first fastener tape part and a second fastener tape part respectively located on a front surface and a back surface of the fastener tape body. Moreover, a fixing holding part is further disposed between the first fastener tape part and the second fastener tape part for maintaining the folded state of the fastener tape body.

First claim

What is claimed is:

1. A fastener tape, comprising:
a faster tape body including a first fastener tape part, a second fastener tape part, a bent part and a fixing holding part, wherein the bent part connects the first fastener tape part and the second fastener tape part, and the first fastener tape part is disposed at a first side of the fastener tape body, the second fastener tape part is disposed at a second side of the fastener tape body opposite to the first side, and the second fastener tape body is fixed to the first fastener tape body by the fixing holding part,
a plurality of fastener elements extending along a length direction of the fastener tape, wherein the plurality of fastener elements are fixed to the first side of the fastener tape body and away from the bent part and the fixing holding part,
in a width direction orthogonal to the length direction of the fastener tape, a width dimension of the fixing holding part is 10% to 50% of a width dimension of the first fastener tape part of the fastener tape body,
the fixing holding part is a component different from the bent part,
the fixing holding part comprises a thermally welded structure directly contacting the first fastener tape part and the second fastener tape part.

2. The fastener tape according to claim 1 , wherein
the fixing holding part is adjacent to the bent part.

3. A fastener tape, comprising:
a faster tape body including a first fastener tape part, a second fastener tape part, a bent part and a fixing holding part, wherein the bent part connects the first fastener tape part and the second fastener tape part, and the first fastener tape part is disposed at a first side of the fastener tape body, the second fastener tape part is disposed at a second side of the fastener tape body opposite to the first side, and the second fastener tape body is fixed to the first fastener tape body by the fixing holding part,
a plurality of fastener elements extending along a length direction of the fastener tape, wherein the plurality of fastener elements are fixed to the first side of the fastener tape body and away from the bent part and the fixing holding part,
in a width direction orthogonal to the length direction of the fastener tape, a width dimension of the fixing holding part is 10% to 50% of a width dimension of the first fastener tape part of the fastener tape body,
the fixing holding part is a component different from the bent part,
the fixing holding part comprises an adhesive layer disposed between the first fastener tape part and the second fastener tape part to fix the second fastener tape part to the first fastener tape part.

4. The fastener tape according to claim 3 , wherein
the fixing holding part is adjacent to the bent part.
