Abstract

There is provided a slide fastener stringer. A substrate tape includes a first main side having a rough surface structure perceptible to the eye and/or the touch and a second main side opposite to the first main side. A gripping member is affixed to a longitudinal edge of the first main side of the substrate tape. A cover sheet is made of an artificial flexible material and has a 5 top surface provided with a predetermined design and a bottom layer made of a thermoformable material having a predetermined thickness. The bottom layer is attached to the second main side of the substrate tape such that the surface structure of the second main side of the substrate tape is not perceivable through the cover sheet.

First claim

The invention claimed is:

1. A slide fastener stringer, comprising:
a substrate tape comprising a first main side having a first rough surface structure perceptible to the eye and/or the touch and a second main side opposite to the first main side, the second main side having a second rough surface structure;
gripping means affixed to a longitudinal edge of the first main side of the substrate tape; and
a cover sheet made of an artificial flexible material and having a top surface provided with a predetermined design and a bottom layer made of a thermoformable material having a predetermined thickness,
wherein the bottom layer is attached to the second main side of the substrate tape such that the second rough surface structure of the second main side of the substrate tape is not perceivable through the cover sheet,
the first and second rough surface structures are irregular surfaces comprised of a plurality of convexes and concaves,
the cover sheet is attached to the substrate tape by means of a resin film,
the bottom layer of the cover sheet is made of a compressible material, and
the bottom layer is compressed in a thickness direction thereof to absorb the convexes and concaves of the second main side such that the second rough surface structure of the second main side is not perceivable through the cover sheet.

2. The slide fastener stringer according to claim 1 , wherein the substrate tape includes a fabric made of interlaced, woven, knitted or knotted fibers, filaments, threads or yarns.

3. The slide fastener stringer according to claim 1 , wherein the gripping means comprise a coil-like coupling element stitched to the substrate tape.

4. The slide fastener stringer according to claim 3 , wherein the coupling element is stitched to at least one of the substrate tape and the cover sheet.

5. The slide fastener stringer according to claim 1 , wherein neither a thickness of the substrate tape nor a thickness of the cover sheet is 50% greater than the other.

6. The slide fastener stringer according to claim 1 , wherein
a width of the substrate tape is greater than a width of the cover sheet and an outer end portion of the second main side of the substrate tape is exposed to the outside.

7. A method for manufacturing a slide fastener stringer, the method comprising:
providing a substrate band comprising a first main side having a first rough surface structure perceptible to the eye and/or the touch and a second main side opposite to the first main side, the second main side having a second rough surface structure;
providing a cover band made of an artificial flexible material and having a top surface provided with a predetermined design and a bottom layer made of a thermoformable material having a predetermined thickness;
adhesively attaching the bottom layer of the cover band to the second main side of the substrate band such that the bottom layer of the cover band is essentially complementarily conformed to the second rough surface structure of the second main side of the substrate band,
the first and second rough surface structures are irregular surfaces comprised of a plurality of convexes and concaves,
the cover band is attached to the substrate band by means of a resin film,
the bottom layer of the cover band is made of a compressible material, and
the bottom layer is compressed in a thickness direction thereof to absorb the convexes and concaves of the second main side such that the second rough surface structure of the second main side is not perceivable through the cover band.

8. The method according to claim 7 , wherein a gripping member is affixed to the first main side of the substrate band after the cover band is affixed to the substrate band.

9. The method according to claim 7 , wherein a gripping member is affixed to the first main side of the substrate band before the cover band is affixed to the substrate band.

10. The method according to claim 7 , wherein the substrate band and the cover band are cut at the center thereof in a width direction.

11. The method according to claim 7 , wherein
a width of the substrate band is greater than a width of the cover band and outer end portions of the second main side of the substrate band are exposed to the outside.
