Abstract: A device for sterilization in production of packages (8) is adapted for sterilization with a gaseous sterilizing agent which is kept in the gaseous phase throughout the sterilization process. The device comprises a heating zone (2), a sterilization zone (3) and a venting zone (4). It further comprises means for maintaining a higher pressure in the sterilization zone (3) than in the heating zone (2) and venting zone (4). A method of sterilizing packages (8) in production of the packages (8) is also disclosed. The packages (8) have an open end (11) and a closed end (12) A gaseous sterilizing agent is used and kept in the gaseous phase throughout the sterilization process. A positive pressure is maintained in a sterilization zone (3) in which the sterilization is performed.

Abstract: A method of sterilizing packages in production of the packages, wherein the packages have an open end and a closed end. A gaseous sterilizing agent is used and kept in the gaseous phase throughout the sterilization process and an ambient temperature and a concentration of sterilizing agent in a sterilization zone where sterilization is performed are measured and used for controlling the amount of sterilizing agent introduced in the sterilization zone.

Abstract: A device (1) for sterilization in production of packages (8) is adapted for sterilization with a gaseous sterilizing agent kept in the gaseous phase throughout the sterilization process. The device (1) comprises a heating zone (2), a sterilization zone (3) and a venting zone (4). It further comprises an ambient temperature sensor (27) for sensing the ambient temperature outside the device (1), a concentration meter (29) for measuring the concentration of sterilizing agent in the sterilization zone (3) and a first control unit for controlling the amount of sterilizing agent introduced in the sterilization zone (3) based on the temperature measured by the ambient temperature sensor (27) and the concentration measured by the concentration meter (29). A method of sterilizing packages (8) in production of the packages (8) is also disclosed.

Abstract: A process for the manufacturing of a core forming a carrying structure for decorative laminates. The core comprises particles of cured, and optionally foamed, rigid, polyurethane, polyisocyanurate and/or phenolic resin. The particles are bonded to each other in a pressing procedure with a bonding agent comprising an adhesive such as a polymerizing monomer. i) The particles are achieved by grinding cured, and optionally foamed, rigid, polyurethane, polyisocyanurate and/or phenolic resin so that it passes through a 2 mm screen, preferably a 1 mm screen, ii) 100 parts per weight of particles is mixed with 1-100 parts per weight of fiber, the fiber additive having an average length in the range 1-15 mm.

Abstract: A process for the manufacturing of a board, used as a core, forming a carrying structure for decorative laminates. Particles are achieved by grinding cured, and possibly foamed, rigid, polyurethane, polyisocyanurate and/or phenolic resin so that it passes through a 2 mm screen, preferably a 1 mm screen.

Abstract: A process for the manufacture of a floor element, which floor element comprises an upper decorative surface, a lower surface, core forming a carrying structure and edges intended for joining. An upper surface web and a lower surface web is fed between the belts of a continuous belt press. A mixture comprising at least one di, tri or polyhydric alcohol and at least one isocyanate, having an isocyanate functionality at least two, in a ratio yielding a polyurethane with a density in the range of 600-1400 kg/m3 is applied between the upper surface web and the lower surface web while said webs are fed between the belts of the continuous belt press. The belts are arranged to allow a substantially uniform and specified material thickness to form, whereby a polyurethane core is formed between said surface webs and whereby said surface webs bond to said core.

Abstract: A process for the manufacturing of floor elements, which floor elements comprise an upper decorative surface and a lower surface, edges intended for joining and a core forming a carrying structure. A mixture of polyols, such as polyester or polyether, crude methylene diphenyl diisocyanate and possibly a small amount of blowing agent in a ratio forming a polymeric resin with a density in the range 600-1400 kg/m3 is injected or cast into a mold, whereby a slightly porous or solid polyurethane core is formed.

Abstract: A process for the manufacturing of floor elements, which floor elements comprises an upper decorative surface a lower surface, edges intended for joining and a core forming a carrying structure. At least a first surface web or a number of first surface webs and possibly a second surface web or a number of second surface webs is fed between the belts of a continuous belt press. A mixture of polyols, such as polyester or polyether, crude methylene diphenyl diisocyanate and possibly a small amount of blowing agent in a ratio forming a polymeric resin with a density in the range 600-1400kg/m3 is then applied between the first surface web and the optional second surface web while being fed in between the belts of the continuous belt press. The belts are arranged to allow a mainly uniform and specified material thickness to form, whereby a slightly porous or solid polyurethane core is formed and possibly bonded to the first surface web and possibly the optional second web.
