ABSTRACT OF THE DISCLOSURE Sheet material (14), such as a continuous supply of terry cloth towel (16), is moved along its length through a path and toward a cutting station (15) where it is cut into lengths (139). The sheet material is formed with bands (166) extending across its length, such as bands of reduced thickness, and the sheet material is cut in these bands. The bands are detected by rollers (144, 145) at opposite edges of the sheet material as the bands approach the cutting station (15), and each edge portion of the sheet material is fed by feed rollers (51, 52) independently of the other edge portion into the cutting station so as to cause one side of the sheet material which may lag the other side to be properly located at the cutting station prior to cutting the sheet material. The sheet material is pulled taut across its length by cylinders (155, 156) at positions straddling the cutting station and on opposite sides of the longitudinal centerline of the sheet material so that the filler threads of the sheet material are induced to extend at a right angle with respect to the longitudinal centerline of the sheet material, and the cut is then made across the sheet material.
