Abstract
The present invention relates to a method and a device for producing a roll () made of a material web () of flexible material which is guided via a contact roller () of a winder and is wound in the said winder to form a roll (), wherein the contact roller () maintains contact with the roll () during winding and the wrap angle (α) of the material web () passing over the contact roller (), as the former is progressively wound, is maintained throughout at a variable reference value predetermined for each winding. In this way the wrap angle (α) for the winding can be adapted to the respective composition of the material web (), which improves the quality of the winding.
