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.

A winder for winding a traveling paper web into a paper roll, comprising:
- two support drums having respective longitudinal axes which extend substantially parallel to each other;
- two nip rolls having respective longitudinal axes which extend substantially parallel to said longitudinal axes of said support drums;
- a support body carrying said two nip rolls;
- means for pivoting said two nip rolls when the paper roll has a particular diameter, such that said two nip rolls define an essentially sealed space with said support body and a portion of a shell surface of the paper roll;
- and
- a vacuum port disposed in communication with said sealed space.
A winder for winding a traveling paper web into at least one paper roll, comprising:
- at least one support drum having a longitudinal axis;
- at least one pair of nip rolls respectively associated with each paper roll to be wound, each said pair of nip rolls having respective longitudinal axes which extend substantially parallel to said longitudinal axis of each said support drum;
- a support body associated with and carrying at least one said pair of nip rolls;
- means for pivoting each said pair of nip rolls when the associated paper roll has a particular diameter, such that each said pair of nip rolls define an essentially sealed space with said support body and a portion of a shell surface of the associated paper roll;
- and
- at least one vacuum port respectively disposed in communication with said sealed space of each said pair of nip rolls.
