The machine has a housing (1) provided with a supply-opening (37) at a supply end. Screw-boreholes (11, 12) with a longitudinal axis, are formed in the housing. Screw-shafts (13, 14) are arranged in the screw-boreholes in a rotatable manner. A speed reduction- and branching gear (16) stays in drive connection with a drive-motor. An output-shaft (18) is connected with the screw-shafts. A sliding connection (24) is formed in a direction of the longitudinal axis between the housing and the gear. The sliding connection has an adapter (25) with a screw-borehole-section connected with the housing.
