Abstract
In a winder device for winding a moving web, such as paper or cardboard web, to form a roll of considerable weight, the roll is carried by support members giving it peripheral support. The support members comprise a rotatable winder drum, transmitting the web to the roll, and a movable support web device. The support members are arranged to form the main support of the roll. The support web device includes a support web having a portion between two rotatable support elements and this support web portion has a roll supporting surface of contact with the roll. The surface of contact is continuously enlarged when said roll grows, in order to eliminate the risk of roll damages due to excess support pressure when winding heavy rolls.
