Abstract
Abstract An apparatus for splicing lengths of textile fabric and the like in end to end relation by the application heat to a heat fusible bonding material is illustrated wherein one of a pair of movable jaws has a face presenting a herringbone configuration with alternate ridges and depressions extending diagonally across the jaw to produce a splice presenting substantially uniform resistance to longitudinal force exerted on the fabric but which permits lateral stretching of the splice.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
150 words
For use in an apparatus for splicing lengths of textile fabric in end to end relation by application of heat to heat fusible bonding material at overlapping end portions of said lengths of fabric, having a narrow elongated first jaw and a complementary second jaw, at least one of said jaws being heated, each being movable toward and away from the other for such application of heat, the improvement including: a series of alternate ridges and depressions extending along a face of one of said jaws forming a substantially herringbone configuration thereacross; and said ridges and depressions on one side of said face converge toward said ridges and depressions on the other side of said face at a medial portion thereof; whereby a splice formed between said jaws across said fabric offers a uniform resistance to longitudinal forces exerted on said fabric but which permits lateral stretching of the splice.
