<p>PURPOSE:To provide a method for controlling the number of rotations during the start of discharge from a rubber extruder almost without initial time loss and material loss when the operation starts as well as without fear of mouth piece damage. CONSTITUTION:The subject method for controlling a rubber extruder consists of two steps, i.e., to automatically control the number of rotations of the extruder 10 so that the internal pressure of a head 11 of the extruder is maintained to a ceiling value at which a mouth piece 12 is not damaged, after detection of the pressure, and to release the control at the time when the number of rotations of the extruder 10 arrives at a setting value. Thus the number of rotations of the rubber extruder during the start of discharge is controlled.</p> |
