ABSTRACT:
An apparatus for aligning the cross-seams of similar lateral edges of two composite limp material segments, where each composite limp material segment includes two panels joined at a cross-seam extending transversely from corresponding points in the lateral edges-to-be-aligned. Following alignment of the cross-seams of the lateral edges, the segments are fed from the apparatus with the lateral edges and corresponding points of the cross-seams in overlapping alignment. Thereafter, the aligned edges may be joined using a conventional sewing machine.
