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.
