    摘要: 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.

    摘要: 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.
