Abstract:
In a cartoning machine, a conveyor conveys flat folded cartons with their end flaps projecting laterally. A rotating disk having a horizontally-projecting pin engages the flaps in timed relation to their longitudinal movement to press a lower major flap downwardly. When in a downward attitude, the major flap is engaged by a plow or hold-down guide which holds the flap during erection of the carton and loading of the carton.
Abstract:
Carriers of the top gripping type and having downwardly depending side and end walls and stacked in collapsed condition in a hopper are fed in sequence by oscillatable feeder means which engages a lower planar element of the lowermost carton in the stack of cartons and draws that element outwardly from its associated face contacting element by means of inwardly extending projections fixedly mounted on the hopper and arranged to engage parts of the upper planar elements which coincide with edge notches formed on the lower planar element so that movement of the lower planar element away from the upper planar element initiates setting up of the carrier and also effects withdrawal of the lowermost carrier from the hopper.
Abstract:
Apparatus for erecting a bottle carrier. The carrier is initially formed as a flat folded tube having a bottom wall, a top wall and transversely creased end walls, the top wall forming a central partition. The apparatus has a longitudinal partition former which is spaced to create a longitudinal slot and end formers which are spaced from the longitudinal formers to create end slots. A blade passing through a hole in the bottom wall engages the inside surface of the top wall to drive it into the longitudinal slot. This operation creates the central partition and simultaneously erects the end walls as the carrier is thrust into the forming apparatus.
Abstract:
Method and apparatus for erecting a polygonal carton from a collapsed envelope (blank) are disclosed. The carton is preferably a two-ply hexagonal carton having a bottom that forms automatically as the oppositely disposed sidewall-forming panels of the envelope are separated. An improved envelope for use with the apparatus is also disclosed.
Abstract:
Method and apparatus for forming a tray are disclosed. The tray has at least one transverse hollow wall formed by a pair of substantially parallel, spaced flaps that are folded down from a transverse bridge. Each flap is secured to a tab folded upwards from the bottom of the tray. A pair of pivotally-mounted folding arms located above the tray rotate the two flaps downwardly while a mandrel located beneath the tray forces the two tabs upwardly into a substantially parallel, spaced relationship, whereby each tab contacts and becomes secured to its respective flap.
