[0001] RUNNING CUTTER FOR SHEET ROLL FORMING SYSTEM [0002]

The present invention relates to a running cutter for a sheet roll forming apparatus, and more particularly, to a running cutter for a sheet roll forming apparatus which cuts a coil material to a predetermined size prior to a roll forming step in a roll forming forming step, .

Generally, the roll forming method is a method in which a roll former unit which rolls a coil and constitutes a pair of an upper roll and a lower roll is passed through a roll former unit which is arranged in a row in multiple stages and is bent and formed into various shapes. A straight type beam current which is bent and formed into various shapes is produced.

FIG. 1 is a step-by-step roll forming process according to a conventional roll forming method for achieving the roll forming method.
