Patent number: 5992489Abstract: A container forming apparatus having multiple working stations for producing a two piece, open top, closed bottom container including means for feeding flat blanks to a first rotating turret; the first rotary turret fixed for rotation about a horizontal axis, and having a plurality of radially projecting mandrels thereon. Container bottoms are fed to the first rotating turret upstream of the flat blanks relative to a direction of rotation of the turret, and each of the flat blanks is folded in succession about respective mandrels. The bottoms are secured to each of the blanks by a vacuum at a first station to thereby form individual container assemblies. The drive indexes the turret so that each mandrel is rotated to successive workstations arranged circumferentially about the first turret. The successive workstations include at least one container bottom heating station, a bottom curl station and at least one bottom expander station.Type: GrantFiled: August 28, 1997Date of Patent: November 30, 1999Assignee: Sweetheart Cup Company Inc.Inventor: Charles E.
