Abstract

An adhesive tape (1) which requires a smaller amount of adhesive by comparison with conventional adhesive tapes having the same adhesive properties is obtained using a method for producing an adhesive tape, which method comprises the following steps: a) mixing an ASE thickener with water and producing an (ASE) thickener-water mixture (7); b) producing an adhesive dispersion (8) from an adhesive and a solvent; c) providing a textile substrate (2); d) applying the (ASE) thickener-water mixture (7) to the textile substrate; e) applying the adhesive dispersion (8) to the (ASE) thickener-water mixture (7) in order to obtain the adhesive tape; f) drying the obtained adhesive tape; in which method the thickener, in particular the ASE thickener, is saturated with water and the adhesive dispersion (8) is applied after or at the same time as the (ASE) thickener-water mixture (7) is applied.
