Abstract
Work feeding and automatic guidance mechanism are combined in a single curvature-controlled means located on one side of a workpiece being progressively processed in a machine, for instance a stitcher. Accordingly, separate feed dog mechanism or equivalent is eliminated. The feeding-steering means preferably comprises a rotary ring orbitally driven about an operating tool such as a needle, and effects guidance and feeding of the work synchronously in intervals when the tool is disengaged from the work.
