Abstract
Abstract Strapping for orthodontic headgear, wrist watch straps, identificaton straps for hospital use and other uses, comprising a core constituted by a strip of substantially nonstretchable polyester film and a wrapper constituted by a composite strip comprising a layer of polyurethane film and a layer of nonwoven polyester fabric which layers have been bonded together under heat and pressure, the composite strip being wrapped around the side edges of the core with the layer of film on the outside and having its marginal edges overlapped and fused together to form a longitudinal overlap seam by a series of discrete fused stitches, and a method of making the same involving ultrasonic stitching.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
Strapping for orthodontic headgear or other uses comprising a core constituted by a strip of substantially nonstretchable thermoplastic plastic material and a wrapper for the core constituted by a composite strip comprising a layer of thermoplastic film and a layer of thermoplastic padding material bonded to the film, said composite strip being wrapped around the side edges of the core with the layer of film on the outside and the layer of padding material on the inside and having its marginal edges overlapped on one face of the core along the length of the strapping, said overlapping edges being stitched together to form a longitudinal overlap seam for the composite strip by a series of discrete thermoplastic stitches, said series extending longitudinally of the strip and generally centrally of the strip, said stitches being relatively closely spaced longitudinally of the strapping and penetrating through the strapping from one face thereof to the other, whereby the wrapper is thermoplastically sealed by said stitches to the core at opposite faces of the core as well as being thermoplastically longitudinally seamed.
Claim 2
Dependent Claim

Strapping for orthodontic headgear or other uses comprising a core constituted by a strip of substantially nonstretchable thermoplastic plastic material and a wrapper for the core constituted by a composite strip comprising a layer of thermoplastic film and a layer of thermoplastic padding material bonded to the film, said composite strip being wrapped around the side edges of the core with the layer of film on the outside and the layer of padding material on the inside and having its marginal edges overlapped on one face of the core along the length of the strapping, said overlapping edges being stitched together to form a longitudinal overlap seam for the composite strip by a series of discrete thermoplastic stitches, said series extending longitudinally of the strip and generally centrally of the strip, said stitches being relatively closely spaced longitudinally of the strapping and penetrating through the strapping from one face thereof to the other, whereby the wrapper is thermoplastically sealed by said stitches to the core at opposite faces of the core as well as being thermoplastically longitudinally seamed.
Claim 3
Dependent Claim
59 words
Strapping as set forth in claim 1, wherein the composite strip and the core are stitched together on lines extending longitudinally of the strapping on opposite sides of the longitudinal seam by a pair of series of discrete thermoplastic stitches, each of said series extending longitudinally of the strapping with the stitches relatively closely spaced longitudinally of the strapping.
Claim 4
Dependent Claim
19 words
Strapping as set forth in claim 1, wherein the stitches are fused elongate areas extending transversely of the strapping.
Claim 5
Dependent Claim
62 words
Strapping as set forth in claim 3, wherein the composite strip and the core are stitched together on lines extending longitudinally of the strapping on opposite sides of the longitudinal seam by a pair of series of discrete thermoplastic stitches, each of which is an elongate fused area extending longitudinally of the strapping, and being relatively closely spaced longitudinally of the strapping.
Claim 6
Dependent Claim
22 words
Strapping as set forth in claim 1, wherein the film is polyurethane film and the padding material is a nonwoven polyester fabric.
Claim 7
Dependent Claim
16 words
Strapping as set forth in claim 5, wherein the core comprises a strip of polyester film.
