Abstract
Method and device for the reeling of a web. The web is reeled by supporting an outer circumference of the roll being formed with at least two supporting units. A first such unit in a direction of arrival of the web is a carrier roll provided with a mechanical rotating drive over which the web is passed to reeling. The carrier roll forms a reeling nip supporting the roll from below. A press roll is situated above the roll being formed so that the roll being wound is stably maintained in reeling position. The roll is wound about a core in a nip support between the carrier roll, a belt roll, and the upper press roll. When the roll is wound and increased, the reeling continues the nip support by the carrier roll and the upper press roll, and additionally, on a belt supporting zone situated as a direct extension of the support zone of the belt roll. The final stages of the reeling are carried out up to a full roll by extending the belt support zone and, at the same time, by adjusting tensioning of the supporting belt or belts so that the linear loads in the various supporting nips of the roll remain within suitable limits in view of progress of reeling and of quality of the roll so being wound.
