ABSTRACT:
A rewinder having a first winding roll that transports and supports the web, at least one core support plate that is curved for receiving and guiding cores adjacent the first winding roll, and a web separator adjacent the first winding roll and movable into pressing relationship with the web at a velocity at least equal to that of the web. The rewinder of exemplary embodiments winds a web of material a nip defined by the first winding roll, a second winding roll and a rider roll. The web separator of exemplary embodiments comprises a rotatable plurality of fingers that rotates about a common shaft. Because the web separator contacts the web moving at a velocity at least equal to that of the web, the web is effectively separated upstream of the web separator, between the core and the web separator.
