Abstract: A cut off apparatus is provided to be in line with a roll-forming machine and sweep-forming apparatus, and is particularly adapted for adjustably receiving and perpendicularly cutting bumper-length segments from any elongated compound swept article. The cut off apparatus includes a frame having a base, support columns, an overhead support, and support braces. A movable carriage is mounted on the support columns for ascending and descending the support columns. A first arm is pivotally mounted on the carriage, and a second arm is pivotally mounted on the first arm. The first arm includes a stop block for engaging and carrying the second arm when the first arm pivots. A cutter housing is pivotally mounted on the second arm for receiving and cutting the elongated compound swept article. The carriage, first arm, second arm, and cutter housing are maintained in a substantially “weight free” state by a counterbalance means.
