| 161 | HALF CLOSED THERMOPLASTIC HONEYCOMB, THEIR PRODUCTION PROCESS AND EQUIPMENT TO PRODUCE | PCT/BE2005000168 | 2005-11-21 | WO2006053407A8 | 2007-06-07 | PFLUG JOCHEN; VERPOEST IGNACE |
| A half closed thermoplastic folded honeycomb structure is described which is produced from a continuous web of material by plastic deformation perpendicular to the plane of the material to thereby form half-hexagonal cell walls and small connecting areas. By folding in the direction of conveyance the cell walls meet to thereby form the honeycomb structure. | ||||||
| 162 | METHOD FOR THE PRODUCTION OF A SANDWICH STRUCTURE FOR A SANDWICH COMPOSITE | PCT/DE0303798 | 2003-11-14 | WO2004043685A2 | 2004-05-27 | KEHRLE RAINER |
| The invention relates to a method for the production of a sandwich structure for a sandwich composite, whereby the sandwich structure is made from a thin foldable starting material of undefined length. The starting material is folded to give a three-dimensional, multi-faceted, developing structure and the starting material undergoes a contraction of the material web in the longitudinal and width direction and a volume expansion relative to the dimensions of the starting material and can be arranged between two cover layers forming the external surfaces of the sandwich composite and connected to the cover layers by means of gluing or some other connection. According to the invention, a sandwich structure can be achieved in which the starting material is not stretched or compressed but rather continuously folded with accurate surfaces and angles without the introduction of cuts or perforations, whereby the material web, in the unfolded state, is pre-treated in a continuous process from the upper and lower side along curved or several straight contiguous star-shaped fold lines and repeating patterns of fold lines, or within the surfaces defined by the fold lines such that fold edges which permit a kink are generated, whereupon, after the successful pre-treatment, an initiation of the folding process in the region of the fold lines on the upper side and the lower side of the material web is carried out, after the initiation the web is decelerated such as to be folded along the fold lines, acting in the manner of hinges, to give a structure extending into the third dimension and, after the folding process, the material web can be treated to stabilise the folded structure. | ||||||
| 163 | REINFORCED PAPERBOARD PALLET AND RUNNER AND ASSOCIATED MANUFACTURING SYSTEM AND METHOD | PCT/US0221104 | 2002-07-02 | WO2004005142A2 | 2004-01-15 | PERAZZO JOHN R |
| A pallet (10) includes a number of runners (12) which may be sandwiched between upper and lower deck sheets (16, 18) of corrugated paperboard. Each runner (12) is comprised of multiple layers of corrugated paperboard (36) with the flutes (38) of the corrugations oriented vertically to provide compression strength to the runners (12) and the associated pallet (10). Each runner (12) also may include at least one reinforcing insert (40) most preferably of hardboard to provide beam strength to the runner (12) and a band (35) to avoid failure without a prior indication. Moreover, each runner (12) may include portals (31) which permit four-way entry for the tines (28) of a lift truck and inhibit tipping of the load (14) off the tines (28). As a result, the pallet (10) offers significantly greater safety features, strength and resistence to crushing or compression than known paperboard pallet designs, avoids the significant ecological and economic drawbacks of wooden pallets and can be processed in a paperboard recycling station (44) along with paperboard containers, boxes (48) or the like. Moreover, the system and method for manufacturing the runners (12) with reinforcing inserts (40) overcomes problems of delaminating and separation of the adhesively bonded layers (36, 40) of the runner (12). | ||||||
