Abstract
An edge trimmed piece that is cut from a long metal slab with a cutting torch carried along the slab edge is automatically crosscut into short manageable length pieces with a secondary crosscutting torch. Both torches are mounted on the same carriage and the crosscutting torch is periodically activated to move along an acute angular path with respect to the edge trim cut, resulting in an effective crosscut transverse to the main trim cut. The crosscutting operation may be carried out without interruption of the edge trim torch, thereby enhancing productivity and trim cut quality.
