Abstract
A method for extruding a semi-finished product made of elastomeric material. An elastomeric material is fed to an inlet channel of a gear pump with an inlet pressure value and dispensed through an exit channel of the gear pump with an exit pressure value greater than the inlet pressure value. The method detects the exit pressure value and adjusts the operation of the gear pump to maintain a predetermined pressure difference between the exit pressure and the inlet pressure based on the detection of the exit pressure value.
