Abstract
A method for severing gobs of melt extrudate, transporting and placing the gobs in molds for compression molding which includes providing an extrudate from an orifice, providing a plurality of C-shaped nests, continuously moving the C-shaped nests in a path past an orifice to sever a gob from the extrudate being extruded and transporting the gob along the path to a position for delivery to a plurality of tooling moved in succession past a delivery station, and applying a force to the gob axially of each nest to deliver a respective pellet to the tooling. An apparatus is provided for severing gobs from a melt extrudate, transporting the gobs, and delivery the gobs comprising a base and a disk having an axis of rotation supported on the base for rotation about the axis. A plurality of transfer nests are mounted on the disk in circumferentially spaced relation. Each transfer nest has a generally semi-cylindrical inner surface extending about a 180.degree. and has an opening. Each cylindrical surface of the nest has an axis. An extrusion nozzle has an outlet nozzle for extruding hot melt extrudate into the path of each transfer nest such that the extrudate enters the cavity of the transfer nest and the movement of the transfer nest severs a plastic gob from the extrudate. The apparatus is operable to apply a force to the plastic gob at a point circumferentially spaced from the extrusion nozzle to discharge the gob.
