Abstract: A novel and improved method of applying adhesive to one side of a running web of wrapping material for a rod-like filler of filter material for tobacco smoke includes directing toward the one side of the web a stream of adhesive which issues from an open-and-shut orifice of a nozzle, and employing one or more jets of compressed air to vary the direction of flow of the stream so that the adhesive coats one marginal portion as well as the adjacent portion of the major central part of the one side and forms at least one non-linear layer. Once the thus treated web is draped around the filler, the adhesive bonds the two marginal portions of the converted web to each other and simultaneously bonds the central part of the web to the filler.

Abstract: An energy efficient method and apparatus for manufacturing a biodegradable, compostable, liquid-impermeable lined paper bag for containing wet (i.e. food) wastes by which all adhesives used in the process are cold glues applied without using heat and are applied through an extrusion and/or metering application means.

The machine includes a slidable, removable mandrel which cycles between a fiberboard hopper area and a container forming compression area. Each of two side bins provides a fiberboard end panel to the mandrel. Just before the mandrel cycles forward, the suction cups remove two fiberboard end panels, one from each side bin, and pull them next to the mandrel. As the mandrel moves forward, the end panels are bent by the action of two folding elements. Meanwhile, a fiberboard body matt is brought into position in front of the retracted mandrel from an overhead feed unit. Adhesive material is sprayed onto selected parts of the body matt as it is placed into position in front of the mandrel.

Abstract: Automated apparatus for forming paperboard packaging from an integral paperboard blank includes a blade for gathering a central portion of the paperboard blank, causing the width of the blank to contract.

Pistons within the mandrel apply pressure to overlapping portions of the formed blank, to seal those portions together.

Abstract: A method of folding and sealing the major and minor end flaps of a carton to provide a sift proof container wherein the method includes providing a carton having first and second inside and outside major flaps and a pair of minor flaps, and folding the minor flaps to substantially cover an open end of the carton. Opposite sides of the first inside major flap are then mitered and both the first and second major flaps are positioned in open positions with respect to the carton. The carton is then put in motion and, during such motion, an adhesive pattern is applied from a stationary adhesive nozzle member to selected areas of the second outside major flap and the minor flaps. The first inside major flap is then folded onto the minor flaps followed by the second outside major flap which provides direct sealing contact between the second outside major flap and both minor flaps as well as portions of the first inside major flap so as to provide the sift proof carton.

Abstract: The blanks (1) are withdrawn one after another from a storage part (20) by transfer means (21) and are disposed on the cylindrical support surface of a drum (3) driven rotatingly by portions of a revolution. Various processing operations are performed on the blanks either while the drum is rotating or while it is stopped, e.g., folding a flap (16), gluing this flap to a surface portion (15) of the blank, or printing a code (17) on part of the blank. The presence, correct positioning, and proper alignment of the blank on the drum are checked before the aforementioned operations are carried out. After they have been effected, the blank is withdrawn from the drum to be sent on to a packaging machine. The processing apparatus and method can be utilized on a line for processing boxes or the like, particularly cigarette boxes, just before they are assembled to receive their contents.

Abstract: Folded paperboard food cartons having a polymer coating only on the interior surface and sales graphics on a substantially unplasticized clay coated exterior surface are heat sealed at contiguous areas of overlapping flaps wherein the polymer coated interior surface is in direct contact with a small portion of the clay coated exterior surface, or where it is desired to secure together two portions of the clay coated exterior surface. In such heat sealing areas, small and accurately located exterior clay coated carton surface areas are primed with a water based polymer emulsion such as ethylene vinyl acetate that is precisely applied to such areas by a printing press.

Abstract: A die cut and scored carton blank is formed into a carton. The carton blank is placed in a trough having a side wall and at least one retractable stop for turning upwardly elongate edge flaps of the carton blank, with the trough having two end walls for turning up end flaps of the carton blank. The partially-formed carton is then moved to a second position where it is lowered and horizontal glue strips are applied to an outer surface of an elongate edge flap. As the carton is moved toward the second position, glue strips are applied to end flaps of the carton blank. The partially-formed carton is then moved to an upper position, above the level of the trough, and into a compression chamber where side walls and end walls hold the flaps together until the glue hardens.

Abstract: A machine or machine section for squaring folded container blanks has a conveyor for conveying slotted and partially folded container blanks. A folding device completes folding of each container blank while being conveyed by the conveyor. A gauge plate is inserted in a slot in each of the slotted and partially folded container blanks. A mechanism moves the gauge plate in timed sequence with the conveyor, inserts the gauge plate in the slot before completion of folding of the respective blank in order to "square" the folded blank, and then withdraws the gauge plate from the slot. Overlapping flaps of each folded blank may be tacked together during "squaring" by drops of hot melt adhesive which subsequently hold the flat folded blanks square while the conventional slow drying water soluble glue dries. The "squaring" arrangement may be incorporated in a conventional gluer/folder machine.

Abstract: A method and apparatus for lining bulk box blanks starting with flat, seamed blanks and resulting in flat, lined, tubular blanks. Glue is applied across the length of the seamed blanks excluding the seam regions. After a liner is placed on the adhesive bearing surface of the blank the blank and liner are moved together to a compression station in a direction transverse to the direction of glue application. The liner and blank are pressed together in the compression station and then forwarded to a folding station where the blank quarter sections defined by preformed seams and slits are folded together atop the remaining, intermediate half section to form a flattened tubular blank. While the blank is enroute to the folding station, glue is applied to a flap along the edge of one quarter section to secure the two unattached edges of the blank together to form the tubular blank.
