FOLDED HONEYCOMB MADE OF CORRUGATED CARDBOARD, PROCESS AND APPARATUS FOR ITS PRODUCTION

The invention relates to a folded honeycomb structure and to a method and device for producing said folded honey- comb structure from a corrugated core web. The folded honeycomb structure has a number of adjacent corrugated core strips which lie in one plane and are in- terconnected by cover layer strips. Said cover layer strips are folded about 180.degree. and are perpendicular to said plane. Ac- cording to the inventive method for pro- ducing the folded honeycomb structure, interconnected corrugated core strips are produced first by making a number of longitudinal scores in a corrugated core web. These corrugated core strips are then alternately rotated through 90.degree. re- spectively so that the cover layer strips fold and the folded honeycomb structure is formed. The device corresponding to this method consists of a number of rotating blades for making the longitudinal scores and a number of guiding elements for rotating the interconnecting corrugated core strips.

Method for fabricating cellular structural panels

An apparatus for manufacturing cellular laminate structural panels includes one or more supply stations of a flexible strip material including folding rollers for sequentially folding the strip material into cellular structures and feeding the cellular structures into a conveyor where the cellular structures are held in compression. The apparatus further includes a laminating station where the folded cellular structures are laminated to an upper and/or lower sheet material to which lines of a bonding medium have been applied prior to engagement with the cellular structures. The folded cellular structures are heated before engaging the sheet material so as to enhance the bonding of the sheet material to the cellular structures and subsequent to bonding, the laminate is passed through a cooling station to set the bonding medium. Downstream from the laminating station, the laminate passes through a side edge folding station where edges of the sheet material are folded over side edges of the laminate to finish the side edges of the laminate and subsequently the laminate is passed into a cutter for cutting the continuous laminate into predetermined lengths. Ends of the cut panels then receive rigid edge strips to fully finish the panel. The method of the invention includes the steps performed by the components of the apparatus.

Honeycomb core structure - with firm bond to end facing sheets

A cellular honeycomb core structure combprises a concentina-type cellular core formed of fold strips of a width equal to the depth of the cellular structure, so that the core can be folded flat with all the strips parallel and of a width equal to the depth of the core when opended and has closure walls across the ends of the cells constituting the outer faces of the complete structure, these walls being bonded to the transverse cell walls over a bonding area approximately equal to the cross section of each cell. In a preferred manufacturing method, the facing sheets receive an inner coating of cool foaming platic just before they are applied to the cellular core, in contact with the facing sheets this foam expands forming a plug in the open end of each cell so that the facing sheets are firmly bonded to the core itself.

Cell-like structural material - has cell walls with grooves to reduce initial resistance for absorbing kinetic energy

The cell-like material is formed from strips, which have been connected at distances to each other. The strips consist of resin-impregnated fibre material, or aluminium foil, and have cut-out grooves in each of the sections, in which they are connected, and in each intermediate section. Each groove has a depth of between 4 and 15% of the strip width. All cells have a hexagonal cross section. The cell structure may be formed by welding or bonding together a series of zig-zag strips to an adjacent similar pair, with the grooves already formed.
