In an overedge stitch type consisting of two needle threads, one looper thread and a workpiece carrying these threads, loops of the needle threads are arranged at different spacings parallel to the edge of the workpiece within the latter. In addition, these loops of the needle threads may also exhibit different spacing from the workpiece edge.

Overedge stitch seam

A new stitch type and a method of and an apparatus for making same in which the loop is passed through the fabric through one hole and is returned through another hole and then is passed around a thread supply eye so that the body of the loop engages a single strand of the thread which twists around this loop and is drawn into the second hole. Such pairs of holes are spaced along the seam so that on one side of the fabric the stitches are spaced apart, i.e. the thread is alternately visible and invisible whereas on the opposite side the thread is continuously visible.

Decorative stitch type and method of and apparatus for producing same

Stitches on alternate sides of a fabric workpiece are produced by the operation of a sewing machine whose needle has a laterally open eye formed with a double-hook contour so that a thread is carried downwardly through the fabric by the eye during a first phase of the initial reciprocation cycle of the needle, the needle is withdrawn upwardly through the fabric without thread during the second phase of this cycle, the needle passes downwardly through the fabric without a thread during the first phase of the next cycle and carries the thread upwardly through the fabric during the second phase of this latter cycle. Below the fabric is a rotary disk having a hook which engages the thread as it passes downwardly through the fabric to draw an entire free thread length out and enable same to be positioned by a thread taker for engagement in the eye of the needle during the upstroke of its second cycle. Above the fabric is a swingable hook which is provided to guide the free thread length upwardly through the fabric following the upstroke of the second cycle and prior to the next downstroke by which the process is repeated while holding the thread length along the needle.
