Abstract
A method is provided using a winder to afford precise adjustment, preferably control of the progression of line force between the reel drum and the wound roll despite unevenness in the surface contour of the wound roll, and ensures that no air entrapment occurs between the individual layers in the wound roll. Further, the “wound in” web tension is maintained during the entire winding process.

A method for the continuous winding of a material web onto a reel spool to create a wound roll, comprising the steps of:
- guiding the material web over a shell surface of a reel drum;
- establishing a winding nip at a line of contact between said reel drum and the wound roll;
- winding the wound roll;
- detecting at least one of long-wave diameter variations and short-wave diameter variations;
- and
- adjusting a line force along said line of contact at said winding nip, said adjusting step being dependent upon variations detected in said detecting step.
A winder for the continuous winding of a material web onto a reel spool to create a wound roll, comprising:
- a plurality of support elements positioned in a side-by-side manner relative to each other;
- a cross shaft to which said support elements are attached;
- a reel drum defining a winding nip with the wound roll, said reel drum comprising a deflection compensation roll including a roll shell being internally supported by said support elements, said support elements configured to adjust a line of force along said winding nip;
- at least one of a long-wave detector associated with the wound roll and a short-wave detector associated with said reel drum;
- and
- a contact pressure device coupled with said reel drum for moving said reel drum.
