Abstract: Described herein is a process for obtaining a container (100) of a given shape starting from sheet material, comprising the steps of: - providing a sheet (110); - providing a mould (20) having a forming cavity (20A), which defines a reference axis (R) and has a shape corresponding to said given shape of said container (100); - positioning said sheet (110) over said forming cavity (20A); - providing a forming device (40) having forming means (41, 42) arranged on the side of said sheet opposite to said forming cavity, and operating said means for inserting said sheet (110) into said forming cavity (20A) to deform it until a container blank is obtained (101) having a shape approximating said given shape; and - blowing a gas under pressure into said forming cavity (20A) to deform said container blank (101) until said container (100) with said given shape is obtained. The process described enables use of sheet material of reduced thickness as compared to conventional processes.

Abstract: The present invention relates to dry cellulose forming method for forming an essentially non-flat cellulose product (14) from cellulose fibres comprising the steps of: separating cellulose fibres from a dry cellulose material in at least one separating unit (3), providing the separated cellulose fibres onto a support structure (8) for forming a sheet of cellulose fibres, forming said essentially non flat cellulose product (14) by pressing said cellulose blank with a moulding tool (11) for forming said essentially non-flat cellulose product, wherein said method further comprising the step of imprinting said sheet of cellulose fibre by providing an imprinted pattern onto said sheet of cellulose fibre by at least one imprinting means (lOa-e) before forming said essentially non-flat cellulose product (14). The invention also relates to a dry cellulose forming apparatus (100) for manufacturing an essentially non-flat shaped cellulose product from cellulose fibres.
