Abstract: The invention relates to a method of rerolling a rolled-up material web, in particular a rolled-up material web of an elastic material on a rerolling device. Furthermore, the invention relates to a rerolling device for performing the method. 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.

Abstract: A coextrusion apparatus, a single-layer extrusion apparatus, a retrofit kit, as well as to a method for measuring a layer thickness, for producing a plastic film, and for retrofitting an extrusion apparatus. From the state of the art, it is known to add a detection agent in the form of a fluorescent granulate into the starting material at the extruder, in order to be able to measure the layer thickness of the layer in the film composite produced from this starting material. However, it is proposed to feed in a detection agent only beyond the extruder. This leads to a clearly shorter running time of the detection agent through the system and thereby to clearly faster measurability of changes in the production parameters.
