Abstract: Method for uniform coating of a composition onto a carrier material in web form, through the use of a coating apparatus comprising at least one element A, that forms with a further element B a nip ahead of which the composition is held up, and that moves relative to the element B in such a way that a rotating body of composition is developed and the composition is conveyed into the nip; comprising introduction of the composition into the intake region of the nip, the application of the composition to a carrier material in web form in the nip or after the composition has travelled through the nip, and which limits the longitudinal extent E of the nip intake region fully fillable by the body of composition.

Abstract: Calendering devices and processes are provided that process a fluid that has been rendered adhesive or is inherently adhesive, wherein processing typically involves forming of the fluid into a film of defined layer thickness and applying the fluid to a carrier material, post-calendering, or a combination of at least two of the above-mentioned processes. The devices may comprise 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 or between 9 μm and 13 μm.
