Abstract
An invisible stitch hemming device for sewing tubular workpieces having first and second vertical walls interconnected and angularly disposed one to the other. A feeler element disposed in close proximity with the walls detects areas of the workpiece having increased thickness and is operatively connected to an actuating means which is effective when such areas are detected in displacing the first wall to permit unrestricted advance of the workpiece and simultaneously the second wall moves to a position for maintaining the workpiece in alignment with the sewing axis.
