ABSTRACT:
A program controlled stitching apparatus and method suitable for embroidery operations, and the like, is provided. The typical Jacquard card pin reader, Jacquard mechanism and the two-dimensional pantograph found in conventional embroidery machines are eliminated. A digital motion control replaces the Jacquard mechanism and a high precision X-Y motion table replaces the conventional pantograph. A minicomputer controls both X-Y motions and sewing mechanisms. A unique program control is employed with the minicomputer providing improved means for detecting stitch faults, thread breaks and accommodating to a wide range of pattern variations and operational situations.
