ABSTRACT:
A continuous, non-hesitant apparatus and process for producing a molded body of plastics material and for simultaneously securing the molded body to a tubular body by means of a plurality of heading units mounted in series on a continuous conveyor, each heading unit having a mold cavity associated with the mold arm slidably positionable with respect to a mandrel arm having a mandrel, press rod and mold core secured thereto, the mold core and press rod in coaxial alignment with the mold cavity, each of which responsive to a camming surface, the tubular body positioned on the mandrel and brought in registration with a continuous web of hot plastics material which is positioned at one end of the tubular body, the tubular body and mold core then positioned within the mold cavity responsive to the camming surfaces for a time sufficient to form the molded body and secure the molded body to the tubular body, the molded body and tubular body then released from the heading unit, the heading unit recirculating to obtain another in a series of tubular bodies.
