ABSTRACT:
Two workpiece plies, placed on one another, of which the lower one is larger in width than the upper one, are to be sewn together with their edge contours aligned with each other. The device used for this purpose comprises a cutting mechanism provided ahead of the sewing machine in a workpiece feed direction, and following the contour of the upper work ply by means of guide unit for sensing this contour, so that the projecting portion of the work ply is cut off. To prevent the work plies from mutual displacement during their feeding toward the sewing machine, they are secured to each other by spot sealing at some locations wherefor a sealing tape is introduced between the plies.
