Apparatus for cutting and delivering plastic gobs

An apparatus for severing gobs from a melt extrudate, transporting the gobs, and delivering the gobs comprising

• a base,
• a disk having an axis of rotation,
• means for supporting said disk on said base for rotation about said axis,
• a plurality of transfer nests mounted on said disk in circumferentially spaced relation,
• each transfer nest having a generally semi-cylindrical inner surface extending about 180.degree. and having an opening,
• each cylindrical surface of said nest having an axis,
• extrusion nozzle means having an outlet nozzle for extruding hot melt extrudate into the path of each transfer nest such that the extrudate enters a cavity of the transfer nest and the movement of the transfer nest severs a plastic gob from the extrudate,
• means on the base operable to apply a force to the plastic gob at a point circumferentially spaced from the extrusion nozzle means to discharge the gob,
• means for conditioning the temperature of each nest to retain the gob without sticking.

An apparatus for severing gobs from a melt extrudate, transporting the gobs, and delivering the gobs successively to cavities of a compression molding machine which includes tooling including cavities, said tooling and cavities being movable in an arcuate path about a first vertical axis comprising

• a base,
• a disk having a second axis of rotation,
• means for supporting said disk on said base for rotation about said second axis spaced from said first axis,
• a plurality of transfer nests mounted on said disk in circumferentially spaced relation,
• each transfer nest having a generally semi-cylindrical inner surface extending about 180.degree. and having an opening,
• each said transfer nest having means closing one end of said opening,
• each cylindrical surface of said nest having an axis,
• extrusion nozzle means having an outlet nozzle for extruding hot melt extrudate through the other end of said cavity into the path of each transfer nest such that the extrudate enters a cavity of the transfer nest and the movement of the transfer nest severs a plastic gob from the extrudate,
• means on the base operable to apply a force to the plastic gob at a point circumferentially spaced from the extrusion nozzle means to discharge the gob into the upper end of a cavity.

An apparatus for severing gobs from a melt extrudate, transporting the gobs, delivering the gobs successively to cavities and compression molding the gobs in the cavities comprising

• a compression molding machine comprising a plurality of cavities and tooling including cavities for compression molding gobs delivered to said cavities, said cavities and tooling being movable in an arcuate path about a first vertical axis,
• a base separate from said compression molding machine,
• a disk having a second axis of rotation,
• means for supporting said disk on said base for rotation about said second axis spaced from said first axis,
• a plurality of transfer nests mounted on said disk in circumferentially spaced relation,
• the path of said nests overlapping the path of said cavities,
• each transfer nest having a generally semi-cylindrical inner surface extending about 180.degree. and having an opening,
• each said transfer nest having means closing one end of said opening,
• each cylindrical surface of said nest having an axis,
• extrusion nozzle means having an outlet nozzle for extruding hot melt extrudate through the other end of said cavity into the path of each transfer nest such that the extrudate enters a cavity of the transfer nest and the movement of the transfer nest severs a plastic gob from the extrudate,
• means on the base operable to apply a force to the plastic gob at a point circumferentially spaced from the extrusion nozzle means to discharge the gob into a cavity of the compression molding machine.
