METHOD AND ARRANGEMENT FOR PRODUCING A FIBRE PRODUCT

The invention relates to a method and an arrangement for manufacturing a fib re product. The method and the process are characterised in that a first male mould (6) is immersed in stock in a moulding tank (2a). By means of a vacuum , fibres are induced to form a fibre layer of predetermined thickness on the male mould (6). The male mould (6) is thereafter removed from the moulding tank (2a) and a female mould (8) is brought under force against the male mou ld (6) in order to express the stock water, following which the fibre product ( P) is transferred to the female mould (8). A second male mould (10) is brought under force against the female mould (8) so that the fibre product is subjected to pressing in order to increase the dry solids content of the fib re product and give this a predetermined external structure, following which th e fibre product (P) is released and subjected to final drying under the effect of microwave or IR radiation.

PROCESS FOR PREPARING FIBER BOARDS

A process for manufacturing fiber boards and similar wood-based products from a lignocellulosic raw material having a moisture content of at least 10 wt.%. According to the process, an aqueous fraction is separated from the fibres of the raw material, which fraction later is recycled to the process in order to form at least a part of the agent used for binding the fibres. Before mixing with the fibres, the aqueous effluent is concentrated and enzymatically oxidized in the presence of oxygen in order to polymerize the solubilized wood material and in order to increase its concentration. Lignin can be added to the water solubilized wood material or the solubilized wood material can be added to the fibres together with another binder. Eventually, the mixture is formed into a board and hardened.

Method and apparatus for manufacturing a food packaging container

This invention relates to a method of manufacturing a food packaging container 10, an apparatus for manufacturing a food packaging container and a food packaging container 10 produced according to the method. To manufacture the food packaging container, a two-stage moulding process is utilised. In particular, following the introduction of a water-based sugar cane pulp solution to a moulding chamber, the water is then extracted (e.g. under vacuum) from the sugar cane pulp solution through a meshed first tooling head which defines an approximate profile of the food packaging container. Subsequently, the sugar cane pulp profile obtained is then transferred to a second tooling head and appropriate pressure and heat are applied. The water-based sugar cane may be rolled and compressed to form a lid. After transferring food into the container, the latter and the lid may be aligned and heat and pressure applied to form a peelable lid. The resulting container is, entirely, biodegradable and compostable.

960,941. Ingot moulds; mould and core materials. FOSECO TRADING A.G. March 21, 1963 [April 11, 1962], No. 14047/62. Heading B3F. [Also in Division B5] In a method of producing linings or hot tops for ingot moulds, a pulp slurry is made from a fibrous organic material and other solid refractory ingredients, e.g. waste newsprint, silica flow, asbestos, quartz, or calcined dolomite, mixed with excess of water, a thermosetting binding agent, e.g. both a urea formaldehyde and a phenol formaldehyde resin, being added to the aqueous slurry which is then charged into a moulding vessel having a wall (e.g. of wire mesh) which is permeable only to the liquid medium, the binding agent being precipitated from the slurry either before or after charging to the moulding vessel, the liquid medium then passing through the permeable wall leaving behind a compacted mass of the solid constitents of the slurry which is subsequently heated to dry them and to cure the binding agent. The binding agent is precipitated by adjusting the pH of the slurry, e.g. to pH5 by the addition of a sufficient quantity of sodium or potassium bisulphate. Air pressure may be applied to the slurry to aid the liquid medium to pass through the moulding vessel.
