Corrugation device for sheets of paper material

摘要

Provided is a corrugation device for sheets of paper material including two corrugation cylinders having work surfaces configured to substantially engage reciprocally so as to define a deformation zone and impress a deformation force on sheets of paper material and at least one thrust member suitable to define a working configuration in which it exerts on one of the work surfaces an additional pressure able to vary the deformation force and a rest configuration in which it does not exert the additional pressure.

1. A corrugation device for sheets of paper material comprising:
two corrugation cylinders having work surfaces configured to substantially reciprocally engage defining a deformation zone and impress a deformation force on said sheets of paper material; at least one thrust member configured to exert an additional pressure on one of said work surfaces, whereby the additional pressure varies said deformation force, and a rest configuration in which the thrust member does not exert said additional pressure on said work surfaces.
