Abstract: A rigid, shaped board structure is formed from a sheet of material having a length and width. The sheet has a first side and a second side. The sheet of material is folded in an accordion fold defining a plurality of flutes. The flutes have first and second legs opposing one another, defined by parallel material fold lines such that a width of the first legs is about equal to a width of the second legs. An adhesive is applied on at least one of each opposing first and second legs. The sheet of material with the adhesive thereon is compressed to fold along the fold lines to form a flat compressed board. The flat compressed board is folded along at least one board fold line parallel to the material fold lines to form the rigid, shaped board structure.

Abstract: A bag having a tamper evident closure and methods of forming the same are provided. The bag has a tube body with a front wall and a back wall positioned between a first end and a second end. A back flap extension member connects to and extends outwardly from the second end of the back wall. A primer material is positioned on the back flap extension member and an adhesive material is placed on the back flap extension member that folds over to overlie and contact the primer material. The back flap extension member adheres to the front flap extension member and portions of the front wall to close the second end. When the back flap extension member liftingly separates from the front wall, at least one of the back flap extension member and the front wall tears indicating evidence of tampering.

Abstract: A case sealer for overlap flap type boxes wherein the major flaps extend greater than ½ the width of the carton. The case sealer uses a folding shoe for folding the inner major flap and then holding the inner major flap and a trailing minor flap in folded position until a plough folds a leading minor flap and the overlies the inner major flap and at least the leading minor flap at least until the outer major flap traps the trailing and leading flaps and thus the inner major flap in folded position.

Abstract: A paster which serves to apply a film of adhesive material to the underside of a running web of flexible material, such as tipping paper in a filter cigarette maker, has a roller which supplies successive increments of the film to the underside of the running web and cooperates with a biasing device which rides on the web and urges certain portions of the underside of the web against the roller. The length of the area of contact between the biasing device and the upper side of the running web is less than the width of the web. This renders it possible to prevent or to minimize undesirable flow of adhesive laterally beyond the marginal zones of the web as well as into perforations which are customarily provided in webs of tipping paper.

In order to fix the parts (101, 101', 201, 201') to each other a cold adhesive is used, that is an adhesive which is fluid at ambient temperature, whereas in order to hold said parts (101, 101', 201, 201') laid over each other in the formed condition of the packet, while the cold adhesive is drying, at least one spot of adhesive consisting of a hotmelt adhesive is applied to at least one of the opposing surfaces of at least one of the associated parts (101, 101', 201, 201') and in an area (17) not coinciding with the area (16) to which the cold adhesive is applied.

Abstract: A method and adhesive pattern for reverse folding and sealing a carton that enables the carton to be sift proof, the method including providing a carton having a first open end including first and second inside and outside major flaps and a pair of opposing minor flaps. The minor flaps and outside major flap are initially folded in an open position and the first inside major flap is folded to cover the open end of the carton. Multiple beads of adhesive are then applied with a non-contact application head to selected areas of the first inside major flap, the second outside major flap and both of the minor flaps. The minor flaps are then folded on top of the first inside major flap and the second outside major flap is folded on top of the minor flaps to provide sealing contact between the flaps about the entire periphery of the first open end so that the carton is sift proof.

Abstract: A mailing container having upper and lower plain paper layers padded with at least two layers of globular paper is made with feed and unwinding devices for upper and lower paper webs and an unwinding device for the padded webs. A device connects the paper webs with padded webs adjacent an edge of the mailing containers. A device cuts the mailing containers to a predetermined format. A station for globular paper includes at least one supply roll to be unwound from the upper paper web and a lower paper web. A reactivatable hot melt adhesive is applied along predetermined zones, on at least one of the globular paper webs and on at least one web of the upper and lower paper webs before the webs are brought together. The hot melt adhesive applied to the predetermined zones between the upper and lower paper web and/or between the globular paper webs causes these webs to be permanently joined.

Abstract: The invention relates to a high-integrity closure, sift-proof carton [10], a method and an adhesive dispensing apparatus for producing same. Foamed hot melt adhesive is dispensed in parallel strips from dispensing guns onto the flaps [20], [22], [30], [32] of the carton [10], which are thereafter folded down to close the carton [10]. The strips can be spaced so that a continuous tight adhesive seal is formed, especially by providing a strip pattern interdigitating when the flaps contact each other. Since all strips are provided in parallel, while the carton is moved with respect to the dispensing apparatus, application of adhesive is fast and reliable.

Abstract: Gum applying apparatus including a pair of gum applying dies mounted on a common shaft for applying gum along and adjacent to the side edges of an envelope blank during the manufacture of the blank into an envelope. Each of the dies includes a central circular plate and a pair of circular sectors spaced from each other about the circumference of the circular plate. The sectors are in contact with a gummer roll which transfers gum from a container to the sectors. The gum is applied by the sectors to spaced envelope blanks on a conveyor belt beneath the sectors. The space between the sectors is adjacent the conveyor when the space between the blanks on the conveyor traverses the gum applying station thereby precluding gum from being applied to the belt running through the station; but enabling the gum to be applied continually to the envelope blanks. Means are also disclosed to control the amount of gum transferred to the gum applying die sectors.
