Process for the continuous, solvent-free and mastication-free production of pressure-sensitive self-adhesive compositions based on non-thermoplastic elastomers and their coating for producing self-adhesive articles

Process for the continuous solvent-free and mastication-free production of self-adhesive compositions based on non-thermoplastic elastomers in a continuously operating apparatus having a filling section and a compounding consisting of DOLLAR A a) feeding the solid components of the self-adhesive composition, such as elastomers and resins, into the filling section of the aggregate, optionally feeding fillers, dyes and / or crosslinkers, DOLLAR A b) transferring the solid components of the self-adhesive composition from the filling section to the compounding section, DOLLAR A c) adding the liquid components of the self-adhesive composition, such as plasticizers, crosslinkers and / or further tackifier resins to the compounding section , DOLLAR a d) preparing a homogeneous self-adhesive composition in the compounding and DOLLAR a g) discharging the self-adhesive composition, DOLLAR a coating of the self-adhesive composition on a sheet material, wherein the coating of the sheet material with a multi-roll applicator, particularly with a 2- to 5-roll applicator is especially carried out with a 4-roll applicator unit so that the self-adhesive composition is formed when passing through one or more nips to the desired thickness, and wherein the rollers of the applicator unit separately to temperatures of 20 C can be set to 150 C.
