| 摘要 |
The invention relates to wire seals for use in a drying space of a Condebelt TM drying apparatus described in Finnish Patent 54 514. In the apparatus, a material web to be dried passes in a substantially airless space between two metal bands (1, 7), or other similar bands or membranes of good thermal conductivity, together with drying wires. One of the metal bands is arranged to heat and the other is arranged to cool; the heating band (1) evaporates moisture contained in the web (2) to be dried, the moisture condensing on the surface of the cooling band (7), separated from the web to be dried by drying wires (3, 4). The drying space between the bands (1) and (7) of the Condebelt TM apparatus is sealed up at the edges by seals integral with the coarse wire (4) either such that the wire is partly filled close to its edges with sealant stripes (5) extending longitudinally of the wire and being usually slightly thicker than the coarse wire, or such that the seal profiles (9) or strips are attached close to the wire edges or to the wire edges by sewing, vulcanizing, gluing, or a combination of these ways of attachment.
