A mold tool includes: a first tool part and a second tool part that works together with the first tool part. In the closed state, the two tool parts are moved toward one another, and in the open state, the two tool parts are moved away from one another. The mold tool also includes a first mold half in the first tool part and a second mold half in the second tool part. The two mold halves reshape the sheet of material, arranged between the two tool parts, into at least one three-dimensional article when the two tool parts are moved toward one another. The mold tool also includes a cutting device including at least one cutting element and at least one actuating device. The actuating device extends the cutting element in the direction of the sheet of material, to cut the sheet of material.

Examples described herein relate to a molded article provided with a resin part formed with a polyolefin resin composite material, the polyolefin resin composite material containing a polyolefin resin and 10 to 150 parts by mass of cellulose based on 100 parts by mass of the polyolefin resin, wherein an area of an aggregate of the cellulose is less than 20,000 m.sup.2.

A device and a method for the production of a fiber mat is suitable in particular for use in the production of packaging board or fibrous construction elements, from a fibrous source material. The method includes providing the fibrous source material, low-water processing of the fibrous source material in an airflow into raw material including individual fibers and/or fiber bundles, forming of the individual fibers and/or fiber bundles in the airflow by a dry forming method into a fiber mat in such a way that a spatial or three-dimensional structure is formed by the fiber mat and consolidation of the formed fiber mat. The specific volume of the fiber mat is greater than 1.6 cm.sup.3/g, in particular greater than 2 cm.sup.3/g, preferably greater than 3 cm.sup.3/g, and the fiber mat thickness 1 mm, in particular 1.5 mm, preferably 2 mm.

A method of making tree shelters comprises mixing a soil biodegradable resin with wood particles, extruding the resulting mixture through an annular die to form a tube, allowing the resin to cure, and then cutting the extruded tube into predetermined lengths to form tree shelters.

A method and system for generating and maintaining a solid structure is provided. The system includes a frame composed of an interconnected network of pipes configured for transporting liquid, the frame having a substantially spherical shape, a plurality of nozzles uniformly distributed along the pipes, wherein the plurality of nozzles are configured for dispensing liquid, a repository that holds a liquid composed of water and at least one additive, a refrigeration unit configured for refrigerating the liquid from the repository to at least a freezing temperature, and a pump for pumping the liquid from the refrigeration unit through the pipes and out of the nozzles, wherein the system is configured to dispense the liquid at said freezing temperature so as to freeze upon egress and create a solid structure surrounding the pipes. The system may also return melted liquid from the solid structure to the repository.

The present disclosure relates to a hollow board 1 with first and second main surface layers 3, 5. A plurality of distance elements connecting the first and second main surface layers and maintain a predetermined distance there between. The main surface layers include at least a layer of high-density fiber, HDF, board, and a plurality of distance elements are distributed in the space between the main surface layers, and at least some comprise at least one elongate HDF board strip 15 which is oriented such that its longitudinal edges interconnect the first and second main surface layers 3, 5. The HDF boards of the surface layers and of the at least some of the distance elements comprise wood particles bonded by a resin including an isocyanate, such as methylene diphenyl di-isocyanate, MDI.
