Abstract
A double chain stitch is made has by first pushing a needle carrying a needle thread down through goods to be seamed to form below a lower face of the goods a needle-thread loop and then passing a looper carrying a looper thread transversely to a stitching direction parallel to the face through the loop below the lower face to pass the looper thread through the needle-thread loop. Then the looper thread and needle-thread loop are gathered on an element below the lower face and the element is moved with the gathered needle and looper threads away from the needle and looper generally parallel to the face while advancing the goods in the direction to form with the needle-thread loop and looper thread a window. Thereafter the needle is again passed through the window and the gathered needle and looper threads are released from the element so that they engage around the most recently formed needle loop. The steps are then repeated.
