Embodiment Construction

[0073] Figure 1a Shown is a winding device 1 in the form of a double idler winding device, which will also be referred to below simply as an idler winding machine, and has a first idler roller 2 and a view in the web running direction Rx The second supporting rollers 3, said supporting rollers together form a winding bed 4 in which the material roll 5 is located. Of course, a plurality of rolls 5 can also be arranged side by side in the winding bed 5 in the axial direction Ry. At least one idler roller 2, 3 is driven. If the support rollers 2, 3 rotate, then the roll 5 is entrained by friction and thus the web M, for example a paper web, is pulled. The winding device 1 has a cutting section 24 arranged in front of the winding bed 4 for dividing the running web M longitudinally.

[0074] In order to prevent the roll 5 from jumping out of the winding bed 4 and to create a certain winding stiffness for starting the winding, a load roll 6 is arranged above the winding bed 4 . ...

Abstract

The present invention relates to a roller coiling drum which is provided with a roller core. The roller core is provided with a functional layer which is made of basically incompressible elastomer an a radial outer part, and a boundary layer of the roller core is limited through at least one hole and at least one baffle plate. Furthermore the boundary layer, the roller and/or the material roll contact with one another in functionality with one another when a roller clearance is formed, wherein, the roller gap has a width which varies in a winding process. For improving the quality of the material roll, high-quality large-diameter material roll should be generated particularly. For this purpose, the width of the roller gap can reach 58mm to 75mm, preferably the width of the roller gap is in a maximal range of 63mm to 75mm.

Description

technical field [0001] The invention relates to a winding roll with a roll core which has a radially outer functional layer made of an incompressible elastomer and whose boundary layer is delimited by at least one hole and at least one partition , and the winding roller can interactingly contact the mandrel and / or the roll forming a nip, wherein the nip has a width that varies during the winding process. [0002] The invention also relates to a functional layer for a winding roll. [0003] The invention also relates to a winding device for winding a web, especially a paper or board web, for winding a core, especially a mandrel, by means of at least one carrier roller, support roller or load roller A winding roller is wound into a coil, which can interact with the mandrel and / or the coil by forming a nip, wherein the nip has a width that changes during the winding process. [0004] The invention also relates to a method for winding a web, in particular a paper or cardboard we...
