Abstract: A zig-zag folding apparatus includes a slitter blade which forms one or more longitudinally extending slits completely through a comparatively wide web of paper thus forming two or more individual, narrower sections of paper. A spreader device, located downstream from the slitter blade, is effective to produce a longitudinally extending gap or space between the individual paper sections where the slits were formed, and these separated paper sections are each transferred to an individual folding mechanism to form individual stacks of zig-zag folded sheets.

Abstract: A pallet of lightweight corrugated paperboard includes spaced longitudinally extending members intersecting spaced laterally extending members by means of inter-engaging notches in alignment with the cross-members. Either of the longitudinally extending members and laterally extending members may have cutouts forming channels for receiving points for the tines of pallet lifting equipment. The lifting points for the tines are entirely unbroken horizontally extending panels with added support panels increasing the width of the lifting point. Each member is scored on only one side, and symmetrically folded inward to form a solid core of corrugated paperboard panels.

The filter element being an elongated tapered strip having a predetermined transverse dimension at its midsection generally equivalent to the diametral measurement of the interior of said cannister and the initial configuration of the tapered sides being equated to the various chordal dimensions of the interior of the cannister-like means integrated with the folds of the filter element, thereby providing a filter element of controllable increased filtration area.

Abstract: An apparatus for automatically applying a pressure-sensitive tab to the edge of a mailer which includes a feed spool of pressure-sensitive tape. The pressure-sensitive tape is fed through a tape slot of a tape guide block from where it is wound upon a driven windup spool. A pneumatically driven (or, if desired, solenoid driven) punch and die arrangement is positioned so that upon actuation, the die cuts a circular segment of the tape and wiper arms apply the circular cut tape segment to the edges of a mailer. This can be done while the edges of the mailer are stationary or moving parallel to the direction of the tape.

Abstract: A method and apparatus are disclosed for making a leaflet having fold lines and cross folds normal to the fold lines and with an adhesive adhering a lip portion of a long leg of the leaflet to a short leg of the leaflet to avoid leaving a loose edge on the leaflet. Sheets are conveyed in a first direction to a first folding at a first folding station, and then a second conveyor feeds the sheets to travel at right angles to a cross folder at a second folding station. The cross folds are made to a lip portion on a long leg and adhesive applicator applies adhesive to the lip portion which is adhered by the adhesive to a folded panel to form a leaflet having fold lines and cross folds at its edges, thereby eliminating any loose edges. Loose edges may open the leaflet during a high speed conveyance thereof.

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: The known pinless folding machine in the prior art is improved in that the speed-up conveyor belts therein is removed, the drive at an increased speed of the folding drum, the clamping drum and the conveyor belts is abolished, but instead, drive at the same speed as the web is effected for these three members. More particulary, there are provided a first cutter drum and a first cutter receiver drum, a second cutter receiver drum, a head end push-in drum, and drum-round conveyor belts wrapped around the folding drum and traveling at the same speed as the web. Cutting of the web is effected twice between the first cutter drum and the receiver drum therefor and between the second cutter receiver drum and a second cutter device disposed on the folding drum, and the web is perfectly cut by the second cutter device. Accordingly, perfect cutting of the web is effected on the folding drum.

Abstract: Method for manufacturing a picture- and/or textchanging slide, in which a piece of planar material is subdivided into three sections, of which two sections provided with changing strips formed by incisions are folded onto each other and are thereafter shifted in position relative to one another to bring the free ends of the changing strips of one section through the incisions of the other section, whereafter two of the sections are folded together into an envelope enclosing the third section and are glued together with a marginal portion of the third section, after which the slide is cut loose from the third section.

Abstract: To readily open up a multi-sheet folded printed product comprising at least two folded printed sheets or signatures which are placed one insdie the other, there is provided an innermost printed sheet which is, for instance, of greater length at the center in the direction of the fold line than the remaining printed sheets. The innermost printed sheet thus protrudes past the remaining printed sheets by a marginal section or lap at one lateral edge. An opening device now can engage the protruding marginal section and can open up the printed product at the center without difficulties. When the printed product has been completed, i.e. after insertion of an enclosure or inserts into the opened printed product, the marginal section or lap is cut away. Since such marginal section or lap must be cut away only at one printed sheet the loss in material associated with the cutting operation is exceedingly small.

The machine includes a guiding system for the paper fed from a feed roll, with the following elements working in sequence: a pair of rollers for trimming the paper to the required width; a pair of paper shaping and pulling rollers, at least one of which is motor-operated and the other of which can be moved away from the first one during insertion of the paper into the machine; a paper cutter operating in a substantially horizontal direction for cutting across the paper; a former for forming the cut paper inside vertical guides and operating parallel to the cutter; and an inserter for inserting the cut and bent paper into the stator slot and operating in a vertical direction moving through the paper former.

Abstract: A carpeting material of nonwoven synthetic thermoplastic resin fibers, capable of being folded so as to fit onto sharply irregular surfaces such as car trunk liners, made by the process of needle-looming a nonwoven carpeting material having higher and lower melting temperature synthetic thermoplastic resin fibers, subjecting the material to sufficient heat to soften and subsequently harden and rigidify one side of the carpeting, and then punching two substantially parallel rows of regularly spaced slots in the back side of the carpeting material. The slots of one row are arranged so that they are staggered in relation to the slots of the parallel row. The arrangement of slots in the back side of the carpeting enables it to be sharply folded while maintaining tear resistance.

Abstract: A method and apparatus are disclosed for skiving and hemming one or more edges of a paperboard web or blank to improve the sealing qualities of a container made from the paperboard. The paperboard is skived twice generally parallel to its edge, once to define an oblique surface and once to make a flat skived surface. The latter is folded over the former and heat-sealed to a heat sealable material adjacent the skived region, defining a wedge-shaped edge portion. The folded over part is preferably ironed to produce a substantially flat sheet, and the wedge-shaped edge is preferably reshaped at some point in the process to make the entire folded over surface substantially flush with the unskived surface to which it is sealed. The flat skived surface is preferably made by a milling procedure in which the milling teeth strike the material while moving in a direction opposite to that of the motion of the material.

Abstract: Within electroaccounting and data processing centers, the sheets of forms processed by the printing machine, in particular by a laser or fast printing machine, are shaped as a continuous strip, which by means of the apparatus in accordance with the invention is assembled into packages wherein the strip is folded, and the packages are automatically shaped, separated from the strip that comes from the printing machine and transferred to successive processing in a continuous manner without interfering with the printing machine operation.

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.
