ABSTRACT:
A winder for winding a traveling paper web into a paper roll. Two support drums include respective longitudinal axes which extend substantially parallel to each other. Two nip rolls include respective longitudinal axes which extend substantially parallel to the longitudinal axes of the support drums. A support body carries the two nip rolls. The two nip rolls are pivoted when the paper roll has a particular diameter, such that the two nip rolls define an essentially sealed space with the support body and a portion of a shell surface of the paper roll. A vacuum port is disposed in communication with the sealed space.
