  • Method and device for storing and transporting flat glass in a contactless manner
    Publication number: 20030177790
    Abstract: The invention relates to a method and a device for storing and transporting hot flat glass in a contactless manner during glass production, said storage and transportation being carried out on a gas bed which is constructed over a gas permeable bearing surface pertaining to a base (2). Pressurised gas is supplied to the base via a connection (5), said gas being guided through the gas permeable base and then re-evacuated. The aim of the invention is to obtain an optimum pressure distribution above the bearing surface, without any static pressure. In order to achieve this, the base (2) consists of a plurality of interspaced segments (21, 22 . . . 2n) respectively comprising a porous and/or perforated bearing surface (7a) as a gas outlet surface. Evacuation openings (61, 62 . . . 6n) are formed between said segments for evacuating the gas. The segments are preferably formed by bars (7) having a box profile.

  • Device for manufacturing glass gobs
    Publication number: 20020092326
    Abstract: A device for manufacturing glass gobs includes a membrane body of a porous gas transmitting material. Channels for introducing compressed gas into the membrane body extend through the membrane body material and are spaced at a distance from the gas outlet surface of the membrane body. The channels run parallel to or are at an acute angle to the outlet surface. In an alternate embodiment, the channels are open channels at the opposite surface from the outlet surface.
