Method and device for producing reels consisting of a large number of flat objects

Abstract

For improving the quality of rolls (4) in which a large number of flat articles (2) are wound onto a roll core with the help of a winding tape (5), a local additional pressure force is exerted on the periphery of the roll (4) under formation during the winding process. For this purpose, the winding device, which in a known manner includes a device for holding a roll core (1), a device for supplying the articles (2) to a winding point (3) on the periphery of the roll core (1) or of the roll (4) under formation respectively, a device for feeding-in the winding tape (5) under tension to the winding point (3) and a drive for rotating the roll core (1) or of the roll (4) under formation, further includes at least one device (6) for generating the additional pressure force. This device (6), for example, includes a pressure roller (20), a pressure lever (21) and a compression drive (22) and advantageously is arranged such that the compression zone is situated, relative to the winding direction, about 15° to 60° behind the winding point (3).
