Abstract: A method and a device for manufacturing a fiber molding for drinks packaging containers having an improved structure and surface quality. The method includes the following steps: dipping of a forming wire arranged on a toolholder into a pulp slurry, lifting of the toolholder in order to move the covered forming wire completely out of the pulp slurry, compressing of the fiber material in an area of the circumferential edge of the forming wire through inflating of a circumferential collar, relaxing of the pressure in the collar, and removing of the fiber molding. A device for manufacturing of a fiber molding is also provided.
Abstract: A vacuum gripping device comprising a plurality of suction bodies, each comprising a suction chamber for applying to a workpiece to be gripped, a suction valve is associated with each suction point, wherein each suction valve comprises a vacuum supply side for connection to a vacuum supply device and a suction side connected to the suction chamber of the assigned suction body, wherein the suction valve comprises a valve body, moveable between an open position and a closed position, wherein the valve body is arranged on a flexible control membrane which delimits a control chamber; in such a way that the valve body is moveable from the open position into the closed position using deformation of the control membrane, and wherein a membrane cloth extending across multiple or all suction points is arranged in the gripper housing.

Abstract: A papermaking mold for producing a pulp molded article comprising a core of prescribed shape which has a plurality of holes for fluid passage interconnecting the outside and the inside and is made of an elastically deformable material and a fluid-permeable material which covers the outer surface of the core, the fluid-permeable material being capable of forming passages for a fluid in its thickness direction even when pressed and deformed.
Abstract: A pulp molded article is produced by depositing pulp fiber on the outer surface of a papermaking core mold having a plurality of interconnecting paths connecting the outside and the inside to form a pulp deposited body, placing the pulp deposited body in a set of split molds, and then pressing the pulp deposited body for dehydration by a prescribed means.
