Abstract
A sandwich synchronizer for a sewing apparatus. The synchronizer is formed to be interposed between the rotatable drive shaft of a sewing machine and the rotary encoder for the sewing machine. The sandwich synchronizer includes a rotatable synchronizer shaft, an encoder for detecting rotation of the synchronizer shaft, and means at either end of the synchronizer shaft for attaching to the rotary encoder and the rotatable drive shaft. The sandwich synchronizer is a universal synchronizer which can be used in any sewing apparatus, no matter what the manufacturer and no matter what the output of the rotary encoder for that sewing apparatus.
