The sleeve is convertible from its rectangular box-like original form to a flattened display form with portions removed and then back to its reformed rectangular form with an adhesively-attachable tab member to form a partial sidewall to form the reconstituted rectangular box or cover. The method of reestablishing the original cover by reforming the rectangular form is also disclosed.

Abstract: Promotional pieces including pop-up structures and methods for mass production on a web press or the like are disclosed. After manipulating the web to create a double thickness in a region of two pop-up panels, die-cutting of the double-thickness region creates an identical pattern along edges of these panels which creates a desired artistic effect found earlier in hand-assembled items. These pieces may have a pop-up structure which includes a tunnel-like construction having apertures formed along a hinge line between two panels. Die-cutting may also be performed along both edges of a pair of folded-over pop-up panels.

Abstract: An improved method for making promotional pieces wherein a high speed web-press operation results in mass-production of attractive pieces which include three or more interconnected pop-up panels which assume a three-dimensional shape when the outer folder is opened. The preferred method utilizes a plurality of longitudinal slitting and folding steps, together with the application of glue lines in strategic locations, and culminates in the transverse cutting of the continuous moving web to separate each blank in series from the next. A continuous web is preferably longitudinally slit into at least three continuous ribbons which are then manipulated and associated with one another to create an endless series of interconnected pop-up assemblies atop a ribbon consisting of two side-by-side basepieces. In an alternative method, only two ribbons are employed, and pieces having a false backbone are created.

Abstract: A machine and process for making container lid assemblies with a flexible membrane with a pull tab adhesively secured to a rigid ring so that when desired the membrane can be peeled off and removed from the ring to provide access to the container. Individual membranes are cut and separated from a web by rotating dies and individually transferred, accelerated and applied by a rotating anvil cylinder and transfer roller to individual rings which have been preheated sufficiently to activate an adhesive to adhere the membrane about its periphery to the ring. The rings are heated by an induction coil and a downstacker deposits heated rings on a moving conveyor belt which conveys them under the transfer roller where they are urged into firm engagement with a membrane by a resilient applicator pad on the transfer roller and an underlying support roller.

Abstract: A cardboard pack for eggs, or the like, is made of two slitted blanks, the longer one of which is bent into flat-topped and flat-bottomed waves. After the wave bottoms are bonded by adhesive to the flat blank, the wave tops are tucked in and the waves flattened mechanically. After the adhesive bonding, the solid cross-strips at the ends of the flat blanks become unnecessary and are cut off. Precautions are taken to avoid undesired adhesion of strips previously separated by slitting. With the waves flattened, the blanks can be easily stored or transported. The blanks are set up at the place of filling by mechanically raising the waves, bending up the sides of the back to form pockets, inserting the goods, bending over the top strips, and securing them together on their line of abutment. The shorter set of blanks is preprinted.

Abstract: Panels of plastic film are delivered to a perforated vacuum drum which has a knife edged die mounted on its surface. Each panel is laid over the die and rotates with the drum into rolling contact with an anvil roll which firmly presses the film panel against the knife edge to cut the panel. After cutting, the film panel continues to rotate with the drum to a position wherein it registers with a blank having a cut-out opening therein which is covered by the film panel. The areas of the blank surrounding the cut-out opening are covered with an adhesive material which causes the film panel to remain adhered to the blank. The vacuum drum continues to rotate and, after bonding of the panel to the blank, the drum releases the vacuum draw on the panel. The cuts formed in the plastic film panels can be straight lines, lines of perforations, or cut-outs bounding areas which are removed from the panel.

Abstract: Methods for separating and stacking sheets of paper, cardboard and the like delivered from sheet punching machines and consisting of useful and waste portions connected together by small fillets are disclosed. The methods include supplying punched but unseparated sheets onto a severing table, severing the sheets in order to form separate stack portions and depositing these separate stack portions onto a stacking surface after withdrawing the severing table from under the stacked portions.

Abstract: A method and a machine for producing a latticework structure composed of cells of essentially parallelepipedon shape from e.g. paper coated on one side with synthetic resin. The web is formed over a mandrel into a sleeve of square cross-sectional shape while being successively advanced, and the sleeve is cut into bits which are flattened and by a step-by-step feeding mechanism positioned adjacent one another with one bit overlapping the following one over halfway in the transverse direction. The bits are bonded together while so positioned whereby flat elements are formed. These flat elements are stacked on top of one another by a mechanism ensuring that the elements are displaced by one cell width in their longitudinal direction and the stack of elements is then cut into pieces having the desired height of the cells. When extended, these pieces form the desired cellular latticework structure.
