Abstract
The present invention provides a sewing mechanism which is useful for joining fabrics with a brittle thread. The invention provides a sewing mechanism having a needle for stitching a brittle fiber thread through at least one layer of a fibrous fabric, the mechanisms for supplying the sewing thread to the needle on each edge thereof while the needle penetrates the layer or layers of fibrous fabric, thread supply being controlled to equalize the supply on both sides of the needle to prevent axial movement of the thread relative to the needle while the needle moves downwards. The mechanism further supports a revolving spool of a second thread and arranged to insert the second thread through a loop formed by the sewing thread at the remote side of the layer of fibrous fabric.
