Rotary Shear (Corrugated Board)

In a corrugator line the rotary shear cuts the sheets of requested length off the corrugated board web. Often two (duplex) or even three (triplex) rotary shears are installed one upon the other. In this case the corrugated board web is separated by the slitter scorer into several outs and cut with three different cut lengths.


As the rotary shear control has the information about the number of cut sheets, the control also controls the automatic order change of the dry end. The head of the incoming web of the new order is tracked and the first sheet is already cut to the correct length. Additionally, the production data of all orders as well as of the whole shift are recorded and displayed. If a superior planning or master computer is connected to the control of the rotary shear, data transfer is made automatically.


A register mark control synchronizes the cut with the register marks of preprinted web.
