Abstract
Strips of metal and other materials can be rolled, cut and punched by the machine which enables several profiling and shaping processes to be performed while the strip passes between a single pair of rollers. A pair of roller edge-cutting tools cut strips from sheet metal along the edges. A roller pair has upper and lower sections for punching holes in the strip.
