Abstract
A screw machine, in particular an extruder, has a housing which has a supply opening at a supply end. At least one bore with a longitudinal axis is provided, in which a screw shaft is rotatably arranged. The drive takes place by means of a drive motor using a gear, the output shaft of which has a rotary drive connection to the screw shaft. Provided between the housing and the gear is a slide connection, which allows a displacement of the housing relative to the gear in the direction of the longitudinal axis.
