Embodiment Construction

[0048] figure 1 is a schematic side view of the rewinding device 1 according to the invention. The material web 100 wound on the uncoiler 200 on a jumbo roll 210 with a diameter D is rewound by the jumbo roll 210 onto a sub-coil 301 which has a diameter d and is arranged on the coiler 300 .

[0049] The uncoiler 200 and the coiler 300 each have an actuator 201 , 301 by means of which the coil 200 , 300 can be driven and decelerated. During rewinding, the diameter D of the jumbo coil 210 on the uncoiler 200 and the diameter d of the partial coil 301 on the coiler 300 are continuously determined, and using these determined parameters, the actuators 201, 301 are continuously adjusted performance.

[0050] The embodiments shown here are given by way of example only and therefore should not be construed as limiting. Alternative embodiments considered by those skilled in the art are also covered by the scope of protection of the present invention.

Abstract

The invention relates to a method of rerolling a rolled-up material web and a rerolling device. The inventive method of rerolling a rolled-up material web of an elastic material on a rerolling device having an-uncoiler and a recoiler, with the material web being rerolled from a large roll rolled up on the uncoiler and having a diameter D to a section roll to be rolled up on the recoiler, and with the uncoiler and / or the recoiler having an actuator, is characterized in that during rerolling, the diameter D of the large roll on the uncoiler and / or the diameter d of the section roll on the recoiler are continuously determined and the performance of an actuator is continuously adjusted by means of this determined parameter. The terms "continuously determined" and "continuously adjusted" are not only to be understood here as an actually continuous, i. e. ongoing, determining or adjusting process, but also as one that takes place in discrete time intervals, the determining taking place multiple times during the rerolling process.

Description

technical field [0001] The invention relates to a method of rewinding a wound material web, in particular of elastic material, on a rewinding device. Furthermore, the invention relates to a rewinding device for carrying out the method. Background technique [0002] Today, modern high-performance plants for the production of material webs operate with such high output performance and correspondingly such high production speeds that the use of tandem winders is no longer beneficial. The material web is in particular a plastic film produced by casting or blow molding. Nonwoven webs from spunbond or meltblown equipment can also be webs of this material. This web is wound for later further processing to form the final product. During further processing, if required, the roll is unrolled, stretched by a stretching unit consisting of several rollers, cut to width dimensions (segments) by a cutting table, and the material web parts are processed to form individual product. Due ...
