Abstract

See full text

The invention relates to a winding apparatus for winding a material web traveling in a direction of travel, having at least one blade for cutting the material web in a web direction into a plurality of partial material webs, and having a folding apparatus for folding the edges of the partial material webs. To furnish a winding apparatus that enables a material web with folded edges to be wound with as little wrinkling as possible, a folding element is furnished for each edge of the partial material webs. The at least one blade may be moved transversely to the direction of travel using a first oscillating apparatus. Using a second oscillating apparatus, the folding elements for the left-hand edges of the partial material webs, as viewed in the direction of travel, may be moved transversely to the direction of travel. Using a third oscillating apparatus, the folding elements for the right-hand edges of the partial material webs, as viewed in the direction of travel, may be moved transversely to the direction of travel. The first oscillating apparatus, second oscillating apparatus and third oscillating apparatus may be controlled by a control unit in such a manner that the folded edges of the partial material webs may be wound at an offset to one another.
