Combined roll-form device for spine processing in glue binding, with successive processing roll tools combined with axes at right or obtuse angle to transport direction

摘要

The combined roll-form device has successive processing roll tools, such as an equalizing milling cutter (1) with a profiled surface, a low-temperature abrasive roll (2) and a notching milling cutter (3), combined with their rotation axes at a right or obtuse angle to the direction of transportation of the block (4).
