Abstract
Apparatus (10) for partially setting up a blank (12) is disclosed including first suction cups (122) for removing the first blank (12) from a magazine (96). The first suction cups (122) are pivotally mounted to the ends of pivot arms (110) to move the first blank (12) up and over actuators (102) of the magazine (96) as the first blank (12) is moved forward out of the magazine (96). After the lower edge of the first blank (12) passes over the actuators (102), the lower portion of the blank (12) is supported in an intermediate position upon an abutment bar (106). While still secured to the first suction cups (122), second suction cups (78) are secured to the blank (12). The second suction cups (78) tilt the blank (12) to be parallel to and move with upstanding lugs (36) of a conveyor assembly (34). A forming die (38) pushes the blank (12) into the lugs (36) as the forming die (38), blank (12) and the lugs (36) move at a constant speed. The end walls (22) of the blank (12) are slid under stationary guides (146) before the forming die (38) is slid from between the lugs (36) to allow movement of the partially set-up blank (12) with the conveyor assembly (34).
