ABSTRACT:
An apparatus for taking residual solid matter out of an extrusion head of an extruder includes a grasping device for grasping residual solid matter in the extrusion head, and a moving device for moving the grasping device between a grasping position in the extrusion head and an exhausting position on one side of the extrusion head. In order to remove the residual solid matter from the grasping device even if the solid matter firmly adheres to the grasping device, the apparatus further includes a disengaging device for urging the residual solid matter to disengage it from the grasping device when the grasping device has arrived at the exhausting position and released the residual solid matter. A control device is provided for controlling the grasping device, the moving device and the disengaging device.
