  • Extruder with axial displacement
    Patent number: 11865777
    Abstract: An extruder for extrusion of material, the extruder comprising a screw (110), a barrel (120), a controller, and a force sensor wherein at least a section (110b) of the screw (110) is conical and wherein at last a section (120b) of the barrel (120) is conical wherein the extruder (100) is adapted for displacing the screw (110) in an axial direction of the screw (110), such that by an axial displacement of the screw with regard to the barrel the size of a leakage gap (180) between the screw (110) and the barrel (120) is modified, wherein the extruder is adapted for actively obtaining operational characteristics and wherein the controller (160) is adapted for controlling the axial displacement of the screw (110) as a function of the operational characteristics of which at least one is an upward force of the material or an upward force on the screw.
