The present invention relates to a method of manufacturing a cellulose product having a flat or non-flat product shape by a pressure moulding apparatus comprising a forming mould. The forming mould has a forming surface defining said product shape, The method comprises the steps of: arranging a cellulose blank containing less than 45 weight percent water in said forming mould; heating said cellulose blank to a forming temperature in the range of 100? C. to 200? C.; and pressing said cellulose blank by means of said forming mould with a forming pressure acting on the cellulose blank across said forming surface, said forming pressure being in the range of 1 MPa to 100 MPa.

A novel technique for the fabrication of a casket dome lid from, for example, Smooth-One-Side (S1S) hardboard is disclosed. The invention is also directed to the fabrication of a casket lid which has a domed configuration both in the lateral and longitudinal directions of the lid. The method comprises the steps of providing a lid blank having a first end, second end, and a central region; providing a pair of diagonal voids oriented at corners of the first end of said blank and extending inward toward the central region; placing the lid blank in a vacuum fixture; and flexing the lid blank into a domed configuration via the vacuum fixture, such that the blank is domed in both a longitudinal and a transverse direction.

The method of the invention comprises the following steps: (i) cutting the maize stalks so as the less leafy stalk segments, higher than 70 cm, stay on the field; (ii) cutting the less leafy stalk segments as close to the ground as possible; (iii) harvesting the less leafy stalk segments cut in step (ii); (iv) cutting the in step (iii) harvested less leafy stalk segments into 5-50 mm stalk sections; (v) providing a mechanical impact to the stalk sections of step (iv) to obtain a mix containing: f1. said spongy cores forming the superabsorbent pellets fraction, f2. said elongated fiber pieces forming the fibrous matter fraction, f3. and said leaf matter forming the leafy fraction,
(vi) separating the 3 fractions from each other;
(vii) recovering the three fractions f1-f2-f3; The invention also pertains to the so obtained products and to their uses in treatments of liquids or gases.

The present invention discloses an equal-fork pallet comprising a pallet body, wherein the pallet body is provided with a stand structure and a reinforcing structure, the reinforcing structure is a reinforcing rib embodied by a groove structure pressed on the surface of the pallet body, and the reinforcing rib comprises a connection type reinforcing rib and a semi-partition type reinforcing rib, the stand structure comprises a corner stand, an edge stand and a center stand, and neither end of the partition type reinforcing rib is connected to the stand. The present invention has a reasonable structural design and strong pressure bearing capacity, with targeted layout and design of the reinforcing rib centralized position and stress concentration position such as stand. It can overcome the problems of the prior art, such as low local compressive strength of the pallet, proneness to produce stress fracture and local cracking, etc.

An objective of the present invention is to provide a method for producing a cork stopper by compression molding cork grains, which can provide a cork stopper excellent in sealability and safety. There is provided a method for producing a cork stopper, comprising: mixing cork grains and an adhesive; compression molding the mixture to give an intermediate; and then heating the intermediate to expand the cork grains.

A method for dry manufacturing rigid cellulose products having an essentially non-flat general shape from cellulose fibres comprising the steps of: providing a quantity of separated cellulose fibres from a dry cellulose raw material in at least one separating unit, providing the separated cellulose fibres onto a support structure for forming a cellulose blank, producing the rigid cellulose product having essentially non-flat general shape by pressing the cellulose blank in a product forming unit having a moulding tool for forming the rigid cellulose product, by means of at least one imprinting tool before the step of producing the rigid cellulose product, imprinting the cellulose blank by providing an imprinted pattern onto the cellulose blank to increase internal bonding between individual cellulose fibres at the location of the imprinted pattern to prevent mutual separation of the individual cellulose fibres during the pressing of the cellulose blank in the product forming unit.
