Method for processing natural rubber and non-thermoplastic elastomers in the context of preparing an adhesive, said rubber and elastomers being similarly plasticised before they can be blended with other components of a mixture, wherein the plasticising and blending results at least partially by means of an extrusion unit that is made up of at least one planetary roller extruder section/module (3, 4) and an upstream filling part, wherein the planetary roller extruder module (3, 4) consists of - an externally toothed central spindle, - planetary spindles with external toothing that rotate about the central spindle, and - an internal toothed surrounding housing, wherein the planetary spindles mesh with both the central spindle toothing and with the internal toothing of the housing, wherein the toothing is an inclined toothing, such that the individual teeth, in accordance with a pitch of the teeth to the longitudinal axis of the extruder, run like screw threads on the toothed surfaces, wherein the feed material is kneaded between the teeth of the planetary roller extruder module (3, 4) in order to plastify the rubber and the comparable elastomers to enable other components of the mixture to be blended in, characterised in that, the natural rubber and comparable, other non-thermoplastic elastomers to be plasticised in addition to the kneading in the planetary roller extruder module, are subjected to a deformation in at least one dispersion ring. until the rubber and/or the comparable other elastomers to be plasticised exhibits, prior to the compounding in of components of the mixture, a Mooney viscosity of less than 80, preferably less than 70, still more preferably less than 60 and most preferably less than 50, wherein a ring construction is used as the dispersion ring that in a modular construction of the extrusion unit meshes between the planetary roller extruder module housing as far as into a groove of the common central spindle led through both planetary roller extruder modules, and thereby leaves an open passage gap for the feed material, said gap consists of a circular gap between the outer circumference of the ring construction and the base of the groove and that the rubber and the other elastomers are cooled during the plastification. wherein the plasticising and blending results at least partially by means of an extrusion unit that is made up of at least one planetary roller extruder section/module (3, 4) and an upstream filling part, wherein the planetary roller extruder module (3, 4) consists of - an externally toothed central spindle, - planetary spindles with external toothing that rotate about the central spindle, and - an internal toothed surrounding housing, - an externally toothed central spindle, - planetary spindles with external toothing that rotate about the central spindle, and - an internal toothed surrounding housing, wherein the planetary spindles mesh with both the central spindle toothing and with the internal toothing of the housing, wherein the toothing is an inclined toothing, such that the individual teeth, in accordance with a pitch of the teeth to the longitudinal axis of the extruder, run like screw threads on the toothed surfaces, wherein the feed material is kneaded between the teeth of the planetary roller extruder module (3, 4) in order to plastify the rubber and the comparable elastomers to enable other components of the mixture to be blended in, characterised in that, the natural rubber and comparable, other non-thermoplastic elastomers to be plasticised in addition to the kneading in the planetary roller extruder module, are subjected to a deformation in at least one dispersion ring. until the rubber and/or the comparable other elastomers to be plasticised exhibits, prior to the compounding in of components of the mixture, a Mooney viscosity of less than 80, preferably less than 70, still more preferably less than 60 and most preferably less than 50, wherein a ring construction is used as the dispersion ring that in a modular construction of the extrusion unit meshes between the planetary roller extruder module housing as far as into a groove of the common central spindle led through both planetary roller extruder modules, and thereby leaves an open passage gap for the feed material, said gap consists of a circular gap between the outer circumference of the ring construction and the base of the groove and that the rubber and the other elastomers are cooled during the plastification.
