Abstract (en)

Corrugation device (1) for sheets of paper material (10) comprising two corrugation cylinders (21, 22) having work surfaces (21 b, 22b) suitable to substantially engage reciprocally so as to define a deformation zone (20a) and impress a deformation force on sheets of paper material (10) and at least one thrust member (30) suitable to define a working configuration in which it exerts on one of the work surfaces (21 b, 22b) an additional pressure able to vary the deformation force and a rest configuration in which it does not exert the additional pressure.
