摘要： A method of forming a tray includes obtaining a blank, positioning the blank in a blank feeder assembly of a system for forming a tray, moving the blank from the blank feeder assembly to a nipping assembly, and moving the blank to a tray forming assembly, the tray forming assembly including a tray forming apparatus. The method further includes positioning the blank between a first tray forming portion of the tray forming apparatus and a second tray forming portion of the tray forming apparatus, the first tray forming portion includes a forming block that defines an interior, and the second tray forming portion includes a tray forming member, and driving the forming block into engagement with the blank and the tray forming member such that the blank and the tray forming member are at least partially received in the interior of the forming block to form a tray.

摘要： A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

摘要： A method of forming a tray includes obtaining a blank, the blank having a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels. The method further includes positioning the blank in a blank feeder assembly of a system for forming a tray, moving the blank to a tray forming assembly, the tray forming assembly including a tray forming assembly, the tray forming assembly including a turret assembly comprising a plurality of female tray forming members, the tray forming assembly further comprising a piston assembly including a male forming member, positioning the blank between the turret assembly and the piston assembly, and moving the piston assembly into at least partial engagement with the turret assembly to form a tray from the blank.
