ABSTRACT:
An apparatus and method for forming a strip of elastomeric material which is extruded onto a rotating roller where it is initially shaped by a die plate and then finally shaped by a calender roll positioned downstream from the die plate and in close proximity to the surface of the roller providing a finishing gap for finally shaping the strip of elastomeric material. The calender roll may be positioned on the opposite side of the roller from the position the elastomeric material is extruded onto the roller whereby the calender roll resists forces tending to bend the roller. The extruder screw may have a downstream end adjacent the roller for reducing the pressure and for self-cleaning the apparatus.
