Two paper webs saturated with an A-phase phenolic resins and dried to a B-phase are conveyed through separate low melting point metal alloy baths, one web after being corrugated, to convert the resin to a fully cured C-phase, whereafter the webs are joined to form a waterproof single face corrugated web.

Apparatus and method for producing waterproof structural corrugated paperboard

Two paper webs, saturated with a B-phase phenolic resin and dried, are conveyed through separate low melting point metal alloy baths, one web after being corrugated, to convert the resin to a fully cured phase, whereafter the webs are joined to form a structurally rigid waterproof single face corrugated web.

Building wall panels having lightweight hollow core interiors include embodiments suitable for interior and exterior walls, for industrial, commercial or residential buildings, and for multi-story structures. Various methods for making these wall panels are disclosed, including the formation of cast gypsum firewall layers.

Building wall panels of hollow core construction

A continuous, fully automated and highly productive system for the production of open core elements utilizes a fluting method and related apparatus effective for providing large pitch flutes for the input webs used in forming the core elements. A wide variety of core elements can be produced for uses ranging from large light weight building panels to small light weight packing elements.

Method of forming open core web elements

A stress-optimized structural support which may be utilized as a beam or assembled with similar supports to form a building floor or roof panel or a bridge deck utilizes an open core element, made preferably of suitably treated fluted paper, upper and lower thin skin sheets, preferably steel skins, and a layer of concrete poured over the top skin. Modules comprising the hollow core element and the upper and lower skin sheets are fabricated to lengths required for building floor, roof or bridge spans and, when joined by welding or otherwise joining the upper and lower skin sheets of adjacent elements along their full lengths, provide a floor or roof deck structure of a large span with horizontal stresses distributed omnidirectionally. A post-stressing tensile system redistributes and reduces the load on the roof deck by about one-half. Small building decks utilizing the stress redistribution system can be combined to build a large span roof in which multiple tensioning systems are coordinated to simultaneously effect the load redistribution.

Hollow core floor and deck element

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 all panels.

A self-valving vacuum distribution system for a belt-driven sheet conveyor utilizes the sheets to automatically open vacuum control valves sequentially in a downstream direction as the sheet is carried on the belts. The system also automatically adjusts for varying sheet widths to automatically apply vacuum holding force only to the belt conveyor area covered by the sheet.

A corrugator single facer of the type utilizing a large diameter bonding roll and a small diameter corrugating roll provides quick roll change capability by mounting three large diameter bonding rolls on a rotatable turret and carrying corresponding small diameter corrugating rolls in a magazine positioned laterally offset from the machine. By driving the corrugating rolls indirectly through the pressure belt arrangement which supports the lower corrugating roll, roll change is significantly simplified.

Single facer quick change corrugating rolls

A single facer for corrugated paperboard of the type using a very large diameter fluted bonding roll and a much smaller diameter fluted corrugating roll which engages the bonding roll to provide a corrugating nip. The small diameter corrugating roll is made to be resilient so that it is capable of inward deflection in the vicinity of the corrugating nip in order to cushion impact as the rolls interengage along the corrugating nip. This cushioning deflection absorbs vibrational movement due to chordal action of the interengaging flutes, and thereby reduces noise levels, roll wear and improves the quality and consistency of corrugation.

Single facer with resilient small diameter corrugating roll

A single facer for corrugated paperboard of the type using a very large diameter fluted bonding roll and a much smaller diameter fluted corrugating roll which engages the bonding roll to provide a corrugating nip. The small diameter corrugating roll is made to be resilient by utilizing a thin walled roll shell so that it is capable of inward deflection in the corrugating nip in order to cushion impact and absorb the deflection as the rolls interengage along the nip. This cushioning deflection absorbs vibrational movement due to chordal action of the interengaging flutes, and thereby reduces noise level and roll wear and improves the quality and consistency of corrugation. A modified flute profile, compensating for flute pitch variations between the large diameter bonding roll and small diameter corrugating roll, assures uniform flute-to-flute engagement in the corrugating nip. Strategic positioning of the supporting stub shafts for the thin walled small corrugating roll axially outside the flute patterns provides substantially uniform small roll deflection along the nip.

A corrugator single facer of the type utilizing a large diameter bonding and corrugating roll and a small diameter corrugating roll is driven without direct drive applied to either corrugating roll. Instead, the pressure belt arrangement which supports the lower corrugating roll to provide the nipping force includes a series of driven supporting pressure belts that are loaded against the lower corrugating roll and which transmit rotational movement thereto and through the nip to the large diameter bonding roll.

Single facer drive apparatus

A single facer utilizes a pair of corrugating rolls, one of which is of a substantially smaller diameter. The small diameter corrugating roll is captured by a series of backing roll arrangements spaced along the axis of the smaller corrugating roll, each of which backing roll arrangements is independently supported to apply an independently variable backing load to the corrugating roll.

A method and apparatus for producing a single face corrugated web in which a steam cloud is injected between the corrugated medium web and the liner web directly at the line along which the webs converge. This type of steam injection allows faster corrugator speeds without sacrificing bonding quality. An adhesive slurry of water and starch granules is applied to the flute tips to form glue lines on the corrugated web prior to the convergence of the webs. The injected steam cloud directed at the web convergence line adds heat without promoting premature dehydration to facilitate proper conditions for effective cooking of the adhesive slurry to thoroughly gelatinize the adhesive. In some applications, dry steam is preferred because dry steam does not significantly interfere with subsequent dehydration of the adhesive gel during the formation of the initial green bond.
