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: Process for producing partially-self-adhesively treated backing materials comprising partially deformed domes or polygeometric forms of adhesive.

Abstract: Process for the at least partial direct coating of an extensible backing material with a pressure-sensitive adhesive composition, the backing material being guided by a transporting apparatus against a coating apparatus in such a way that the coating apparatus applies the pressure-sensitive adhesive composition to the backing material, characterized in that the coating apparatus is abhesively treated.

Abstract: Process for the at least partial, direct coating of an extensible backing material with a pressure-sensitive adhesive composition, the backing material being guided by a transporting apparatus against a coating apparatus in such a way that the latter applies the pressure-sensitive adhesive composition to the backing material, characterized in that there are adhesion devices or holding devices present on the transporting apparatus so that the properties of the backing are not altered in the course of coating.

Abstract: Backing material with a partial self-adhesive coating on at least one side, the application of the self-adhesive composition taking place in the form of geometric structures, wherein for at least some of the geometric structures the base area by means of which the geometric structures adhere to the backing material lies within the area of projection of the geometric structures which is formed as a consequence of the fact that the geometric structures are projected perpendicularly onto the backing material.
