An apparatus for forming the bottom end wall of a carton from a rectangular carton blank having oppositely disposed scored end panels and oppositely disposed unscored end panels includes a rotating mandrel assembly adapted to receive an open-ended carton blank through an open top end of the carton blank, a heating station, a folding station and a sealing station. The folding station has a pair of oppositely disposed reciprocating break fingers to contact and fold inwardly the scored bottom end panels and biasing means for folding inwardly down the unscored bottom end panels. The folding station is rotatable 90° between two functional orientations, a first orientation wherein the break fingers are aligned in the direction of mandrel movement, and a second orientation in which the break fingers are perpendicular to the direction of mandrel movement. |

DETAILED DESCRIPTION OF THE INVENTION Referring initially to FIG.
1, the present invention can be best understood by considering a known apparatus for forming the bottom end wall of a rectangular carton 12.
Rectangular is intended herein to include cartons having a square cross-section.
The rectangular carton blanks 12 are illustrated in FIG.
2, and have open bottom 24 and top 26 ends, with first 42, second 44, third 46 and fourth 48 body panels adjoining first 50, second 52, third 54 and fourth 56 bottom end closure panels, respectively.
The bottom end closure panels are integral with the body panels to which they are adjoined, with a score line at the juncture between body panels and end panels so that the end panels can readily fold inward to form the bottom end wall of the carton.
The first 50 and third 54 bottom end closure panels are oppositely disposed and are scored to fold inwardly when the second 52 and fourth 56 bottom end closure panels are folded inwardly down to form the bottom of the carton.
As shown in FIG.
2, the scored end panels 50, 54 have two score lines which divide the rectangular panel into three triangular shaped regions, central being an isosceles triangle having as its base the score line between the body panel and the end panel.
The carton 12 is loaded onto an appropriately sized mandrel 16 through the open top end 26 of the carton, with the bottom end closure panels 50, 52, 54, 56 extending beyond a distal free end 20 of the mandrel.
The mandrel is preferably affixed to a turret 18 which, as it rotates, moves the distal free end 20 of the mandrel 16 in a circular path through a series of equally spaced carton processing stations.
As illustrated in FIG.
1, a standard mandrel assembly includes six equally spaced mandrels radially affixed to a rotating turret, although more or fewer mandrels may be employed.
Mandrel assemblies having six mandrels are particularly preferred, as there are generally five or six processing stations required for the carton bottom folding operation
