摘要： A system for producing a multiple layer material (49), comprising first and second corrugation rolls (14, 15) for providing a corrugated profile (16) having a plurality of crests (47), wherein the system further comprises first and second press rolls (21, 22) for applying a material sheet (19, 20) to crests (47) of the corrugated profile (16), and a plurality of heating members (28) arranged between the press rolls (21, 22) for welding the material sheet (19, 20) to the crests (47) of the corrugated profile (16) to form the multiple layer material (49). A guiding plate (48) is arranged between the corrugation rolls (14, 15) and the heating members (28). The guiding plate (16) is arranged with a profile engaging side (50) having a plurality of crests (52) corresponding to the crests (47) of the corrugated profile (16). A cooling arrangement is provided for cooling the guiding plate (48). A method for producing the multiple layer material (49) is also disclosed.

摘要： Method and device for the manufacture of corrugated material, at least one first plane sheet (19; 20) and one second sheet (16) of plastic material arranged in wave shape being brought together for adhesion to each other and the wave-shaped sheet (16) running over core bars (17, 18). A portion of at least one sheet is heated at abutment against the core bars (17, 18) and the first sheet (19; 20) is brought to abutment against the second sheet (16) for welding the sheets (16; 19, 20) together. First members are arranged for feeding at least the first plane sheet and the second sheet of plastic material running over core bars (17, 18) and second members are arranged for bringing together and adhering the sheets. Heating members (28) are arranged for transferring heat to a portion of at least one sheet (16; 19, 20) abutting against the core bars and including plastic material. Furthermore, guide members (17, 18; 21; 22) are arranged for bringing together the first and the second sheet in an abutment portion and for welding in the portion heated by the heating members (28).

摘要： A pallet collar (12) for a pallet (1 1 ), comprising a first element (13), a second element (14), a third element (15) and a fourth element (16), wherein the pal¬ let collar (12) is foldable, and wherein a bottom side and a top side (21 ) of the elements (13-16) is provided with protrusions (22) and recesses (20), respec¬ tively, which recesses (20) are arranged for receiving protrusions (22) of an adjacent pallet collar. The first element (13) and the second element (14) comprise inner protrusions (22a) outer protrusions (22b), wherein a height of the outer protrusions (22b) is arranged so that they are disengaged from cor- responding recesses (20) of an adjacent pallet collar when the third element (15) is lifted from an underlying pallet collar to disengage the inner protru¬ sions (22a) while the fourth element (16) simultaneously engages the under¬ lying pallet collar. The invention is also related to a goods support with such pallet collars and methods for assembly and disassembly thereof.
