High-speed blank set-up 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 forwards 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).

L'invention porte sur un appareil (10) à haute vitesse de dressage partiel d'une forme comprenant de premières ventouses (122) servant à extraire les formes d'un magasin (96), montées pivotantes aux extrémités de bras pivotants (110), et soulevant les formes pour les amener au-dessus des actionneurs (102) du magasin (96) tandis que la première forme (12) sort du magasin (96). Lorsque le bord inférieur de la première forme (12) a dépassé les actionneurs (102), la partie inférieure de la forme (12) est soutenue dans une position intermédiaire par une barre butée (106). Alors que la forme (12) est encore tenue par les premières ventouses (122), de secondes ventouses (78) qui viennent s'y appliquer la redressent pour la rendre parallèle aux arrêtoirs (36) verticaux d'un convoyeur (34) qui l'entraîne. Une matrice (38) de formage pousse la forme (12) dans les arrêtoirs (36) tandis que la matrice (38), la forme (12) et les arrêtoirs (36) progressent à vitesse constante. Les parois d'extrémité (22) de la forme (12) glissent sous des guides fixes (146) avant que la matrice (38) ne glisse hors des arrêtoirs (36) pour permettre à la forme (12) partiellement dressée de suivre le convoyeur (34).
