Extruder specification feed system

Extrusion at a Point away from the Head The adhesive may be extruded from a point away from the applicator head and feeding the material to an on/off valve at a given rate. A system of this type is now available it is based on a hydraulic drive unit which drives the extrusion cylinder piston. The size of the cylinder can be readily tailored to suit the specific applications without imposing excessive loads on the robot wrist.
