Abstract

Sheet material (30) is cut into rectangular segments (35). The segments are then moved parallel to their cut edges rapidly away from the cutting station into a slower operating first sewing station (40) where elastic bands are sewn to the cut head and foot edge portions of the segment. The rapidly moving trailing portion of the segment (35) of sheet material is temporarily accumulated at the accumulation station (39) and progressively fed at a lower rate from the accumulation station to the first sewing station. The head and foot edge portions are folded into overlying relationship with respect to the main body portion by passing the main body portion through a U-shaped turn and at the same time passing the head and foot edge portions though a pair of 90 degree turns. Sewing machines are moved first inwardly and then outwardly across the folded edge portions of the segment, thus forming the sewn line of chain stitching at the corners of the bedsheet.
