ABSTRACT:
A skew control mechanism for sheet material. Sheet material, such as corrugated paperboard, is slit into strips of various widths and the slit strips are then cut transversely into lengths by a cut-off machine. The cut sections are conveyed by an endless belt conveyor to a stacking mechanism, and to prevent skewing of the cut sections on the conveyor, a skew control mechanism is mounted for movement on the frame of the machine. The skew control mechanism includes a series of carriages located along each side of the machine and the carriages at each side are connected together by links, while transverse shafts are pivoted to carriages at opposide sides of the machine. A plurality of wheels are mounted for floating vertical movement about each shaft and the wheels ride on the upper surfaces of the cut sections. An adjusting mechanism is incorporated which enables the shafts to be pivoted with respect to the carriages so that the axes of the wheels can be adjusted with respect to the machine direction and thereby steer the cut sections into proper machine direction alignment.
