Abstract
A method and apparatus for splicing two rolls of tire cord fabric in axially aligned relation. A plurality of splicing rods are forced through overlapped ends of the rolls from opposing longitudinal sides of the fabric. The splicing rods are guided through the overlapped ends at successive points spaced along parallel lines angularly disposed to the parallel warp cords of the fabric and alternately pierce and pass through the pieces of fabric from the farthest spaced faces of the overlapped ends. The splicing rods are firmly snubbed together and held in position by the coaction of the warp cords and weft threads of the fabric, as the fabric is tensioned.
Claims11
A method of splicing at least two pieces of fabric composed of warp cords held in parallel array by weft threads, comprising the steps of:
- (a) holding adjacent ends of the two pieces of fabric in overlapped relation, the warp cords of the overlapped ends being generally parallel;
- (b) forming waves with interconnected ridges and troughs across the overlapped ends such that the longitudinal axes of the ridges and troughs parallel the warp cords;
- and
- (c) moving a plurality of splicing rods across the overlapped ends while guiding the rods into piercing engagement through the waves intermediate the ridges and troughs at successive points spaced along parallel lines angularly disposed to the parallel warp cords and through the overlapped ends alternately from the opposing farthest spaced faces of the overlapped ends.
A method of splicing at least two pieces of fabric composed of warp cords held in parallel array by weft threads, comprising the steps of:
- (a) holding adjacent ends of the two pieces of fabric in overlapped relation, the warp cords of the overlapped ends being generally parallel;
- (b) forming waves with interconnected ridges and troughs across the overlapped ends such that the longitudinal axes of the ridges and troughs parallel the warp cords;
- (c) Moving a plurality of splicing rods across the overlapped ends while guiding the rods into piercing engagement through the waves midway between the ridges and troughs at successive points spaced along parallel lines angularly disposed to the parallel warp cords and through the overlapped ends alternately from the opposing farthest spaced faces of the overlapped ends;
- and
- (d) said rods being interconnected at one end forming a comb with outstanding teeth for piercing the waves.
A method of splicing at least two pieces of fabric composed of warp cords held in parallel array by weft threads, comprising the steps of:
- (a) holding adjacent ends of the two pieces of fabric in overlapped relation, the warp cords of the overlapped ends being generally parallel;
- (b) maintaining the overlapped ends in parallel, planar relation;
- and
- (c) moving a plurality of splicing rods across the overlapped ends while guiding the rods sinuously into piercing engagement with the overlapped ends at successive points spaced along parallel lines angularly disposed to the parallel warp cords and through the overlapped ends alternately from the opposing farthest spaced faces of the overlapped ends.
