ABSTRACT:
A device for simultaneously hemming each side of a continuous planar web of textile or similar material utilizing a pair of known blind-stitch sewing machines, each operating in conventional manner and direction of rotation in synchronism with the other. One of the sewing machines is driven in standard fashion, and the other of said sewing machines is coupled thereto in such manner that varying widths of web may be accommodated in planar condition without the necessity of forming a centrally disposed longitudinally arranged fold in the web. The machine driven in standard fashion is adjustably positionable upon a frame element at varying distances from the other of said sewing machines to accommodate the varying widths. The other machine is in relatively fixed condition upon the frame element, and the parts disposed above and below the web are driven through linkages disposed laterally outward of the frame element, so as to provide a clear path for the web passing therebeneath.
