摘要:
A system and method for producing a board product made from paper products that have embossed medium that features an improved structural profile. The improved structural profile may include a triangular flute pattern wherein each flute may exhibit a first linear leg support and a second linear leg support that each support a center apex structure. The apex may have a substantially flat portion that is configured to engage a facing. As such, the board product may further include one or more facings that are adhesively coupled to the embossed medium. Further, the apex of each “triangle” may also have a groove or channel for receiving an adhesive in a continuous and uniform manner.

The invention relates to a method and an apparatus for the production of a corrugated cardboard product. The apparatus comprises a first one-sided machine and a second one-sided machine which are provided in each case with a press-down belt and with a first and a second grooving roller respectively. The first and the second grooving roller are designed for embossing a wave profile onto a first and a second paper web respectively. The press-down belts serve, together with the respective grooving rollers for connecting the first and the second paper webs in each case to a non-corrugated web for the production of a first and a second single-flute corrugated cardboard web respectively. The first one-sided machine is equipped with a first oblique guide roller the axis of rotation of which is inclined at a vertical inclination angle between side margins of the first paper web.

The invention relates to an apparatus for producing corrugated cardboard products. Said apparatus comprises a first one-sided machine and a second one-sided machine which are configured in each case for producing a single flute corrugated cardboard web. Furthermore, the apparatus has a combining means which is configured for connecting the single flute corrugated cardboard webs. Here, the combining means is provided with a convergence region which is configured for mutual adaptation of the single flute corrugated cardboard webs. Furthermore, the invention relates to a method for producing corrugated cardboard products, in which method a first single flute corrugated cardboard web is connected to a second single flute corrugated cardboard web. During connection, a first single flute corrugated cardboard web and a second single flute corrugated cardboard web run through a convergence region.

A method of preparing water-resistant corrugated paperboard includes providing a corrugated medium treated with a water-proofing agent on both sides thereof, and providing a liner treated with the water-proofing agent on at least an inner surface thereof. The liner and corrugated medium are adhered, with the inner surface of the liner adhered to the corrugated medium. The liner and corrugated medium are adhered with an adhesive composition comprising carrier starch, uncooked pearl starch, borax, a water-proofing resin, a penetration-enhancing additive, and water. The carrier starch comprises cooked starch and uncooked starch. The liner and corrugated medium are treated with the water-proofing agent prior to adhering the liner and corrugated medium. Due to the use of the particular adhesive composition for adhering the liner and the corrugated medium, use of liner treated with the water-proofing agent is possible with acceptable bonding and preservation of Cobb ratings.

A continuous, fully automated and highly productive system for the production of open core elements utilizes various formations of fluted input webs which are cut into strips, glued, cross-transferred, and serially upended for placement against preceding strips to build up an open core element. The open core elements are useful in the manufacture of structural members such as doors, floor panels and to wall panels. Also disclosed is a fluting apparatus effective for providing large pitch flutes for the input webs used in forming the core elements. A glue machine that utilizes a glue roll as the only moving part operates in conjunction with a ganged positive displacement adhesive pump to supply liquid adhesive for application to the flute tips for any of the various glue application stations in the system.

An apparatus and method for the vacuum assisted bonding of sections of corrugated cardboard and for manufacturing corrugated cardboard. A pressure plate has a bore for applying a vacuum therethrough. A first section of corrugated cardboard has an orifice which is aligned with the bore in the pressure plate. Adhesive is applied between the first section of corrugated cardboard and a second section of corrugated cardboard and the second section is placed adjacent to the first section away from the pressure plate. A vacuum is applied through the bore in the pressure plate and orifice in the first sections to cause the first and second sections to be drawn and adhered together. In the manufacture of corrugated cardboard, vacuum and optionally hot air are applied to opposite edges of the sandwiched core of fluted linerboard with adhesive and overlaying flat linerboard to draw them together to form the corrugated cardboard.

The present invention relates to a method of forming a laminated material comprising the steps of corrugating a paper sheet and applying a liner to one or both sides of the corrugated sheet, wherein the liner is a pre-made laminate of a paper backing and plastic film which is metalized on one side and corona or chemically treated on the other side. A laminating apparatus for use in the above method is also described herein, which includes a means for feeding out a paper sheet and a liner to a set of corrugating rollers, the liner being a pre-formed laminate of paper and plastics film, and means for uniting the paper sheet and liner immediately subsequently to the corrugation of the paper sheet.
