The invention relates to a powder press (1) for producing a pressed article from a material that can be pressed, having a press frame (10), an upper and/or lower punch assembly (14) and a die assembly, which define a molding cavity, into which the material that can be pressed can be introduced, and an electric drive unit (12) which is operatively connected to the punch assemblies (14) and/or the die assembly, wherein, in order to mold the pressed article, the punch assemblies (14) and the die assembly can be moved relative to each other along a pressing axis (18) and pressed against each other by means of the electric drive unit (12). Furthermore, the operative connection between the electric drive unit (12) and one of the punch assemblies (14) comprises a toggle lever drive (16) which moves the punch assembly (14) into a pressing end position along the pressing axis (18).

A trash compactor may include a frame, a cavity, a trash receptacle, a platen movable to compress trash collected in the trash receptacle, a set of linkages and a drive mechanism configured to drive said platen up and down, the drive mechanism further configured as one of the link elements, and a platen guide mechanism configured to restrict the motion of the platen in an up and down manner.

A product forming unit for manufacturing non-flat cellulose products from an air-formed cellulose blank structure (2). The product forming unit includes a blank dry-forming module with a moveable forming wire, a toggle pressing module with a toggle press and a forming mold, and an electronic control system operatively connected to the forming wire and the toggle press. The blank dry-forming module is configured for air-forming the cellulose blank structure onto the forming wire. The toggle press includes a pressing member movably arranged in a pressing direction, a toggle-mechanism drivingly connected to the pressing member, and a pressing actuator arrangement drivingly connected to the toggle-mechanism. The forming mold includes a moveable first mold part attached to the pressing member and a second mold part. The electronic control system is configured for controlling operation of the pressing actuator arrangement for performing pressing operations, which involves driving the pressing member in the pressing direction by the toggle-mechanism, and thereby forming the non-flat cellulose product from the air-formed cellulose blank structure by pressing the first mold part against the second mold part. The electronic control system is configured for intermittently feeding the forming wire between subsequent pressing operations.
