Abstract

Abstract An article comprises two areas of heat-recoverable woven fabric which are joined together along a line by means of a mechanical joining arrangement, such as stitches, staples or a stitched or stapled zip, which penetrates the fabric. The direction of crimp of the area penetrated is substantially perpendicular to the line of the join, or the two areas have substantially parallel directions of crimp.

Claim 1
Independent Claim 64 words
An article comprising two areas of woven fabric, at least one of which being heat-recoverable, joined together along a line by means of a mechanical joining arrangement that penetrates at least one of the areas of fabric, said area of fabric penetrated having a direction of crimp that is substantially perpendicular to the line at least along part of the length of the line.
Claim 2
Dependent Claim 64 words
An article comprising two areas of woven fabric, at least one of which being heat-recoverable, joined together along a line by means of a mechanical joining arrangement that penetrates at least one of the areas of fabric, said area of fabric penetrated having a direction of crimp that is substantially perpendicular to the line at least along part of the length of the line.
Claim 3
Dependent Claim 52 words
