A pre-punched material sheet for constructing a packaging trough, the material sheet includes a sub-area that has been punched out incompletely so that the sub-area is connected to a residual area of the material sheet through a plurality of retaining lugs. The material sheet is positioned on top of a female die part of a forming tool and the sub-area at least partially covers an opening of a forming cavity of the female die part. The residual area of the material sheet may be clamped in position against the female die part. The sub-area of the material sheet is sucked onto an insert in the forming cavity using a vacuum. The insert is vertically movable in the forming cavity from a first position to a second position to draw the sheet into the forming cavity and thereby form the packaging trough.

A method and a machine for realizing containers, including at least steps of impressing a shape in relief on a sheet of deformable material, enveloping the sheet about itself and reciprocally joining lateral flaps thereof in order to form a tubular blank, and closing a bottom end of the tubular blank.

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 blank for being formed into a container. The blank has a marginal area that includes a plurality of score lines for facilitating forming of the blank into the container. The score lines are positioned to facilitate formation of the container. A forming tool has features to facilitate forming the blank into the container.

A thermoform packaging machine comprising a forming station. The forming station comprises at least one forming tool lower part, the forming tool lower part may be movable transversely to an operating direction of the thermoform packaging machine. The forming tool lower part may comprise at least one reception unit with one or a plurality of troughs for receiving cardboard elements. At a forming position the forming tool lower parts are in contact with the forming tool upper parts such that the first film web may be formed-in into the forming tool lower parts. Further, the first film web may be formed-in into the cardboard elements during the forming process and, in the case of a skin film, an adhering or an adhesive connection may be established between the skin film and the inner surfaces of the cardboard elements.

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.

A method for producing a cardboard-plastic composite shell (10), in particular an MAP cardboard-plastic composite shell for food products, includes at least the method steps (66, 68, 82, 88) providing a plastic foil (12), pre-forming the plastic foil (12) to form a shell shape (14), providing a cardboard blank (16), and connecting the cardboard blank (16) to the already pre-formed plastic foil (12) in order to form the cardboard-plastic composite shell (10). The cardboard blank (16) provided is not folded or incompletely folded directly before the connection to the pre-formed plastic foil (12). When the cardboard blank (16) is connected to the pre-formed plastic foil (16), the cardboard blank (16) is folded onto the plastic foil (12) by a stamp mechanism (24).

The invention relates to a system (100) for manufacturing a compostable pod (900) for brewing products. Therein, the pod (900) is made from a sheet (600) made of a biodegradable cellulose-based material. The system (100) comprises at least one shaping line (200), which comprises a handling unit (300) for transferring the sheet (600) along a transfer direction (TD) through the system (100). The shaping line (200) further comprises a humidifying unit (400) for moistening at least one side of the sheet (600) with a moistening agent (401), and a forming unit (800) for shaping a part of the moistened sheet (600) into a three-dimensional shape to form a pod element (910), which defines a pod cavity (911). The shaping line (200) comprises further a humidity sensor system (500) for visually sensing a level of humidity of at least a section of the moistened sheet (600). Values related to the level of humidity sensed by the humidity sensor system (500) are received by a control unit (700), which is further configured to control the humidifying unit (400) based on these values. The invention also relates to a method for manufacturing a compostable pod (900), whereby a level of humidity of at least a section of the moistened sheet (600) is visually sensed and forwarded for controlling the moistening process of the at least one side of the sheet (600) correspondingly.

A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100? C. to 200? C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.
