STRUCTURED ROLLERS IN THE CALENDERING AND POST-CALENDERING PROCESS

摘要

With a calendering apparatus, configured and set up to process a fluid that has been rendered adhesive or is inherently adhesive, wherein the processing typically involves the forming of the fluid into a film of defined layer thickness, the application of the fluid to a carrier material, post-calendering, or a combination of at least two of the above-mentioned processes, comprising a feed device for feeding the fluid, a multi-roller mechanism having at least two calendering rollers and at least one calendering nip for processing the fluid, in which at least one of the at least two calendering rollers has an average roughness depth Rz of between 5 µm and 15 µm, in particular between 9 µm and 13 µm, the processing of even very adhesive polymers is allowed.
