Abstract
An arrangement for winding a web on a roll core or the like in a support drum winder, which comprises a first and a second support drum, a web cutter, transfer means for the transfer of a complete wound roll from said support drums, supply means for the supply of a new roll core and guide and retainer devices for governing a web trail end and a front end formed by an engagement of the cutter with the web. The governing is carried out until a supplied core retains said web front end against the first support drum. The arrangement comprises means for a free new core supply from a location above the support drums in a position therebetween. The supply is carried out preferably by the free fall action and during the transfer of the complete roll. The retainer devices comprise retainer members separate from the first drum. These retainer members generate a force action against said first support drum.
