<p>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.</p> |
