ABSTRACT:
An extruder head for extruding an elastomeric composition to form a reinforced elastomer article such as a conveyor belt has a substantially rectangular die opening and a guide member disposed in the opening of the die for directing the reinforcing elements into the composition as it is shaped by the die.
A device is provided for restricting the streams of composition, which flow on opposite sides of the guide member, to have said flow meet said reinforcement along two parallel fronts.
