ABSTRACT:
A semi automatic hemming machine for folding cloth pieces with the edge folded back within the fold, stitching the folded cloth pieces to form hems thereon and stacking the stitched hemmed pieces into bundles for further processing. The folding and hemming machine utilizes a conveyor belt for transporting the cloth pieces continuously past stationary folding guide plates and a pair of synchronized narrow belts engage the folded edge of the material, top and bottom, to frictionally drive the folded hem through the folding and stitching operations. A transversely reciprocating stacker with a plurality of fingers for engaging the edge of passing cloth pieces removes the hemmed cloth pieces, drops them onto a stack which is periodically removed for further processing.
