ABSTRACT:
This invention relates to automatic mechanism for processing the edges of pile type fabrics and the like from which thinner or non-pile margins are to be removed. Fabric edge finishing machines are provided with a means for sensing relative thickness of work piece portions, such as terry material as distinguished from thinner or marginal non-terry portions. Accordingly washcloths and the like, as directed by an edge guide and corner turning mechanism, are under the control of a sensor and are automatically guided through the operating localities of instrumentalities, such as the needle and trimming mechanism of an overedge stitcher, or other edge treating machines, to provide for removal of the non-terry material and processing directly along the edge of the remaining terry material.
