Abstract
A method and apparatus for on-machine winding of a web, including a Pope reeling drum (10) and a reel spool (11). The web (W) to be wound passes over the drum. An empty reel spool (11') is brought into the grip of primary arms in such a way that bearing members (25) of the reel spool (11') are supported by guiding elements located at both sides of the drum (10) in such a manner that the reel spool (11') is not engaged with the drum (10). The empty reel spool (11'), preaccelerated to winding speed, is then brought into nip contact with the rotating reel drum (10), by moving the spool into recesses (21) in the guiding plates thereby forming a nip (10) through which the web (W) passes. The web breaks off and begins to wind onto the empty reel spool (11).
