Abstract: The invention relates to a method and to an apparatus for producing packs, in particular cigarette packs, from blanks (11, 44), wherein individual regions of a pack blank (11) are adhesively bonded to one another and, if appropriate, to one or more separate blanks (44) by the pack blank (11) being provided with individual portions of glue (28, 29) by means of a valve or a group of valves (26) and blank regions which are to be adhesively bonded together subsequently being held or pressed on one another, wherein the individual portions of glue (28, 29) are applied to the blank regions by means of the glue valve (27) or the group of glue valves (26), and/or wherein a control and/or regulating device (65) automatically controls and/or regulates the size or quantity of the respectively produced portion of glue (28, 29), which size or quantity is produced by the at least one glue valve (27) during an individual valve opening cycle, as a function of at least one parameter.

Abstract: A bag has a panel made of film and having an inner face and an outer face and formed with at least two throughgoing and spaced attachment holes. A carry handle has a pair of spaced ends each having an adhesive-coated face engaging the outer face over a respective one of the holes. Respective inner patches each have an adhesive-coated face engaging the inner face over a respective one of the holes and engaged through the respective hole with the end face.

Abstract: Various processes for the creation of a film to film bond using printed patterns of adhesive traces. In some implementations of the process, control of the process including control of the temperature of the adhesive and film to a temperature approaching the heat distortion temperature for the film will vary the strength of the bond from a frangible bond to a bond the tears the film, (a film-tearing bond). Some implementations of the process may be used to produce bonded films at web speed rates that are significantly higher than commercial rates for heat seal processes.

Abstract: A method and system for moistening and sealing an envelope in a high speed mail processing machine including steps and components for heating a liquid to moisten the glue on the envelope flaps to more quickly soften the glue and provide an improved seal.

Abstract: Business forms are sealed by pressure with reduced tenting and pillowing. Each form has a strip of pressure sensitive adhesive of a predetermined width. In an automatic continuous, sequential manner, upper and lower rollers operatively biased together by spring pressure activate the pressure sensitive adhesive to affix one part of the form to another. The force applied by the rollers is applied only to the approximate area of the predetermined width of the adhesive, not over the whole form. Conveyor tapes are associated with the rollers to facilitate conveyance of the forms, and a pressure of about 120 lbs. per lineal inch is applied to the pressure sensitive adhesive. A buckle or insert folder can be used to fold the forms, and they are then fed to a first pressure sealing module. A 90.degree. transfer conveyor conveys the forms from the first pressure sealing module to a second module, and from the second module they are removed by a discharge conveyor.

Abstract: A mechanism for applying adhesive to a sheet comprising a plurality of glue applicators comprising valves or nozzles adapted to form a charge of adhesive at the tip of each. The sheet is moved toward the nozzles to permit adhesive spots to be deposited on the sheet. The nozzles have periods of deactivation after which they are reactivated. A cleaning and moistening sponge (or a tray with appropriate fluids) is provided to maintain the adhesive in the nozzles in usable condition during periods of deactivation so that the adhesive may be immediately used and deposited on the sheet upon reactivation of the nozzles.

Abstract: A method and apparatus for high speed pouch or bag making from thin, extensible heat-sensitive thermoplastic film webs in which the method is applied to a continuously moving web and sealing is achieved at temperatures below the softening temperatures of the film or sealing interfaces. The method of forming an open pouch comprising the steps of continuously pulling an elongated web of pouch forming material at a constant speed along a pouch making path which extends continuously through a web slitting station, a web coating station, a web collating station, an Electron Beam curing station and a web cutting station. An elongated web is slit into first and second webs at the slitting station, a pattern of E.B. curable adhesive is applied to a first surface of the first web as it is pulled continuously through the web coating station to render the first surface bondable at a seal pattern and non-bondable in the area of the storage compartment when subjected to Electron Beam radiation.

Abstract: A method and apparatus for high speed pouch or bag making from thin, extensible heat-sensitive thermoplastic film webs or multiple webs of paper, film and foil in which the seal pattern may be simple or complex sealing and in which the method is applied to a continuously moving web and sealing is achieved at temperatures below the softening temperatures of the film or the sealing interfaces. A method of forming an open pouch comprising the steps of continuously pulling an elongated web of pouch forming material at a constant speed along a pouch making path which extends continuously through a web coating station, a web collating station, an Electron Beam curing station and a web cutting station. A pattern of E.B.

Abstract: A method and apparatus for fabricating continuous envelopes for use in connection with electronic data processing printers or the like is disclosed. The method and apparatus includes the steps of severing an advancing web along longitudinally spaced-apart transverse lines to provide straight completely severed segments and a non-severed medial segment. In a distinct step, the web is severed along non-linear lines adjacent to the transverse lines, with each non-linear line including a severed longitudinal segment and a severed bridging segment which extends in an oblique direction between the transverse line and the outer end of the associated longitudinal segment to provide a generally triangular cut-out which, when both are removed, yields an envelope backing panel having a tapered closure flap.

Abstract: Apparatus for applying gum to spaced portions of an envelope is provided with means for sensing the absence of an envelope on a conveyor belt feeding the envelopes to the gummer apparatus. In response to sensing the absence of an envelope on the conveyor belt, a gummer cylinder containing spaced gummer pads for applying gum to the flap and body of the envelope is precluded from rotating by disengagement of a clutch between the gummer cylinder and its drive and simultaneous contact of a brake with the cylinder.

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.

Abstract: A rotary converting machine gum box is replenished with adhesive by means of a pumped circulation system with a delivery conduit at one end of the gum box and a withdrawal conduit at the other end. Between the two gum box ends is provided a rotatively driven screw shaft to mechanically induce uniformly distributed adhesive flow from said one end to the other.

Abstract: Apparatus for feeding, scoring, gumming, and folding a blank into an envelope.
