ABSTRACT:
A cutoff apparatus is adapted to be positioned adjacent a roll-forming machine, and is particularly adapted for adjustably receiving and cutting bumper-length segments from a swept elongated shape made of high strength steel being extended from the roll-forming machine. The cutoff apparatus includes a carriage with rollers for rollingly engaging the elongated shape to align the carriage with the elongated shape, the carriage being adapted to periodically move with the roll-formed shape for a short distance as the roll-formed shape is being formed. The cutoff apparatus further includes a blade operably mounted to the carriage for cutting segments from the roll-formed shape on the fly. An overhead supporting device supports the carriage in a counterbalanced condition so that the carriage can pivot and/or translate as necessary to minimize undesirable stress on the roll-formed shape as the roll-formed shape extends through the carriage, thus providing a reduced need to critically align and maintain the alignment of the cutoff apparatus with the roll-formed shape.
