Abstract

A device for continuous winding of webs on winding shafts onto winding rollers consisting of arms supporting the winding shaft, a pressure roller that can be engaged on the winding shaft or winding core, a knife separating the web during the roller change, and of a charging electrode supplying the web start with an electrostatic charge, which attaches the web start, newly formed by the web cut, on the winding shaft. In order to always maintain the correct equal distance to the web supplied with the charge, the same is tracked in such a manner that the distance of the charging electrode to the web remains constant regardless of the diameter of the winding shaft.
