Abstract
The continuous paper web, unwound from a feeding roll, is first passed through a perforation station to generate pre-established tear-off lines and then through a severing station where it is severed into sheets of the desired length. From the severing station, the web is advanced to the winding station, to which the cardboard cores supported at their ends by two idle mandrels are also supplied. The winding station is defined by two endless belts diverging from each other in the direction of the outlet from this station and moved at different speeds. At the inlet of the winding station, the cardboard cores are rotated by said belts, whereby the length of paper web advanced to said station by the lower belt is wound onto one of said cores. The so-formed roll is transferred to a discharge station, where it is released by disengaging the mandrels from the ends thereof. The two free mandrels are then transferred to a loading station where they pick up a new cardboard core.
