Form-scoring Patents (Class 493/396)
  • Patent number: 11027513
    Abstract: A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.

  • Patent number: 10279499
    Abstract: A deflectable lifting device can be mounted to a support form, work surface or other member of a material conveyance system. According to embodiments, the deflectable lifting device can have a base that mounts into the support, and a bendable arm arranged in the pathway of a material conveyance system, such as a paper stripping or paper blanking work station. When a sheet or web of material travels over the deflectable lifting device, the bendable arm can bend and deflect downwards, but still contact the sheet or web with a gently humped or arcuate portion, providing a small margin of elevation or lift to the sheet or web. The sheet or web can therefore be elevated above edges, holes, or other obstructions in the pathway that could jam or snag the delivery of the material.

  • Patent number: 7918775
    Abstract: In a method for producing a hinge-like bend line (3a,b, 4a,b or 5a,b) in a sheet (1) of paper, paperboard, cardboard or foil, particularly a brochure cover, by rotatively driven tools (7.1, 7.2), the bending line (3a,b, 4a,b or 5a,b) is produced by roll bending without scoring the material in the form of a scoring bead. The roll bending is preferably realized by the cooperation of a tool edge (12a) of a first rotary tool member (8.1) with a conical outside surface (11a) of a second rotary tool member (9.1). The roll bending process lowers the bending resistance of the sheet (1) in the region of the bending point (3a,b, 4a,b or 5a,b), wherein the sheet (1) is simultaneously pre-bent in a certain direction along the bending point (3a,b, 4a,b), e.g., in order to take into account the position of the brochure cover on the book block at the spine edges (the sheet is pre-bent inward in a U-shaped fashion).

  • Patent number: 5855543
    Abstract: A kit for making boxes from paper card stock. The kit has a flat plate with a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. Two identical sized card stocks are used for each box. A slightly wider spacing strip is used to form the top than the spacing strip used to form the bottom of the box. This also makes the depth of the box bottom slightly greater than the box top.
