Abstract
A bottom folding assembly for a packaging machine is configured to infold the bottom side panels, leading panel and trailing panel of a carton for forming a sealed carton bottom in such a manner as to reduce the contact of rotating elements with the carton material to reduce the generation of dust. The bottom folding assembly is positioned about a rotating turret that defines a turret plane. The mandrels are configured to receive a carton in the tubular form and to carry the carton with the carton positioned such that a bottom of the carton is positioned at a free end of the mandrel. The bottom folding apparatus, located between a carton bottom heater and a carton bottom sealer includes a rotating drive shaft mounted transverse to the turret plane and a pair of opposing rotating members are operably mounted to the drive shaft and are disposed on either side of the turret rotational path. The rotating member rotate in a plane transverse to the turret plane. A tucking assembly is disposed between the opposing rotating members and is mounted to the drive shaft for rotating in a plane transverse to the rotating members and parallel to the turret plane. When a carton is positioned on th…
