An arrangement for winding a web, in particular a paper web, on a roll core or the like in a two-drum winder comprising two support drums and a rider roll surrounding the web core. The arrangement includes means for supplying, during the final stage of a roll winding process, a new roll core between the newly finished roll and the support drums. There are also a web cutter and means for the transfer of a finished roll away from the support drums. The front end of a transversely cut web is guided to form the beginning of a new roll around a new roll core by guiding means comprising a plurality of guiding units spaced-apart in the circumferential direction of the new roll core. These units include means for creating pneumatic jets urging the web tightly around the new core. |
