Embodiment Construction

[0041] exist figure 1 In , firstly the molding mesh 1 is seen, which extends along the outer contour of the molding tool 2 . The molding tool 2 is hollow on the inside and has a plurality of channels 3 which, in the depicted and in this respect preferred embodiment, are designed as drilled holes from suitable points of the molding tool 2 The surface at extends up to the hollow interior of the molding tool 2. The molding tool 2 is located on the tool holder 4 and is connected to the tool holder 4 from below by bolts 5 which may only be partly visible. The tool holder 4 also has a central supply line 6 which can likewise be designed as a borehole.

[0042] Below the tool holder 4 a fixed plate 7 can be seen which in turn has a central supply line for the air supply of the molding tool 2 . The seal 8 , which is preferably designed as an O-ring, provides the necessary impermeability of the contact area between the tool holder 4 and the fixing plate 7 . An expandable sleeve 9 s...

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.

Description

technical field [0001] The invention relates to a method and a device for producing fiber molded parts, in particular head elements or base elements for beverage packaging containers, as well as fiber molded parts produced with the method and device. Background technique [0002] Folded beverage containers made of fiber composite material in various embodiments have been known for a long time. Here, the most common are those containers made from a single blank from a cardboard / plastic composite. However, multi-part containers are also known, in which a head element and / or a base element are inserted into and joined to a tubular packaging sleeve, or in which initially , a container opened at one end is made by folding the ends appropriately, and then the cover element is inserted into the multi-part container, as is known for example from US 4 527 699 or from EP 0 893 355 A2, wherein a Inserted head and base elements made of plastic. [0003] Furthermore, multi-part packag...
