ABSTRACT:
Disclosed is an apparatus for lubricating and beading the edge or rim of a cup having a seamed annular sidewall and a polygonal base. A 360.degree. spray means sprays the inside top margin of the cup wall with water to lubricate and a spinning head having a plurality of radially moveable forming members for contact with the rim subsequently produces the bead. The lubricator has a deflector which moves by means of an air cylinder axially into contact with the top annular wall end to close the end and to direct and combine a water mist created by a 360.degree. spray set up which atomizes the water to a mist by means pressurized air. For the bead forming operation, a base plate together with relatively moveable socket forming wall members provides a seat for the cup on a cam operated elevator device which moves the cup upwardly. The socket is complementary to the polygonal base to prevent rotation of the seated and supported cup relative to the socket. The socket walls retract into a common horizontal plane with the base plate to permit rotationally driven star wheels to first restrain the cups at the lubricating station and then to guide and confine cups onto the base plate in register with the bead forming means and off of the base plate away from the bead forming means. An air stream is directed into the cup to produce a positive pressure which inhibits dust from entering the cup during the bead forming operation.
