Abstract: The blanks (1) are withdrawn one after another from a storage part (20) by transfer means (21) and are disposed on the cylindrical support surface of a drum (3) driven rotatingly by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 After they have been effected, the blank is withdrawn from the drum to be sent on to a packaging machine.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: A carton tray formed from a flat carton blank including a bottom wall panel, four side wall panels integral with the bottom wall panel along four side fold lines and a gusset wall panel integral with each pair of adjacent side wall panels along two end fold lines extending from a corner point in angularly related relation with respect to one another.

Abstract: A modified glue flap of a folding carton blank for preventing glue from being squeezed out during the step of adhering the glue flap to the opposite end panel. The face of the glue flap engaged by the glue back-up wheel includes a protrusion near the trailing edge of the flap. Engagement of the protrusion by the back-up wheel causes the glue wheel to skip the trailing area of the flap. The absence of glue in this area prevents glue from being squeezed out when sealing pressure is subsequently applied to the glue flap and the opposite end panel. The protrusion may take the form of an embossed ridge, forming a channel on the opposite side of the protrusion for receiving any excess glue which would have been squeezed out.

Abstract: A method of forming a sift-proof seal for closure of a box having a plurality of folded flaps, the seal being formed by an adhesive strip pattern. The flaps are moved linearly toward a plurality of nozzles which extrude adhesive in a pattern of closely spaced adhesive strips. A flap having such an adhesive pattern is brought into contact with a second flap to compress the pattern of adhesive therebetween. The spacing between adjacent strips of adhesive is such that the folding of the flap causes merging of the adhesive to form a continuous strip of adhesive, thereby forming a box closure. The adhesive pattern is limited to a first outside edge of the first flap, with each remaining outside edges receiving a sift-proof continuous line of adhesive.

The machine forms the box and automatically glues the auxiliary punched sheets to the box itself.

Abstract: All sealed flaps of a box or carton are provided with viewing window apertures which are in registration with frangible parts of underlying flaps. The underlying flaps have scored areas in the skin portions thereof to which cold glue is applied for sealing the underlying flaps to the flaps having the window apertures. When any of the flaps having the window apertures are pulled open, the skin portions of the underlying flaps are stripped from the main substrate layers of the underlying flaps within the scored areas. This stripping tears the frangible parts of the underlying flaps, such parts being unscored, leaving roughly torn elements of the frangible parts visible through the viewing window apertures. Attempts to reseal the flaps which have been pulled open are ineffective because the viewable torn elements of the frangible parts cause the tampering to be permanently evident.

Abstract: Process and apparatus for forming cigarette packs having rounded or beveled longitudinal edges includes forming the contoured edges on a flat blank at a shaping station as a preliminary shaping step. The shaping station includes a shaping mandrel or plate having rounded or beveled edges and shaping rollers or strips for wrapping the blank about the plate to produce the desired longitudinal edges contours.

Abstract: A machine to form an end of a unit of a box from a flat box blank that includes two sides, a bottom, and, at each end, an end flap supporting a cantilevered sealing tab, and two side tabs supported by the two sides.
