ABSTRACT:
A method for winding a web onto a spool at least partially supported on a support roll in which the web passes through a nip formed between the support roll and a roll formed by the web winding on the spool. The roll being formed is loaded and/or supported by at least one loading/supporting unit which is/are displaced during initial winding stages in a direction substantially in a plane passing through a central axis of the support roll and a central axis of the roll being formed. Thereafter, the loading/supporting unit(s) is/are displaced in a direction substantially along a path parallel to a circumference of the roll being formed, and during final winding stages, the loading/supporting unit(s) is positioned to support the roll being formed from a bottom region thereof.
