Abstract
An extruder head assembly has a main stationary part adapted to be connected to a plurality of extruders, two head parts pivotal on the main part, and respective actuators associated with the pivotal head parts and having piston rods movable along respective longitudinal axes from the respective pivotal head parts to the stationary part. At least one of the actuators is mounted directly on the respective pivotal head part. Latches including interengaging formations on the stationary part and an outer end of the rod of the one actuator lock the pivotal head parts tightly against the stationary main part.
