Abstract
An apparatus for guiding a coated material strip through a dryer has a plurality of guide elements disposed in the dryer so that the plurality of guide elements are equally-spaced. The plurality of guide elements each have a gas-permeable guide face which faces an underside of the coated material strip. A device for supplying a gas to the plurality of guide elements is provided so that a gas stream passes through each of the gas-permeable guide faces and supports the coated material.
Claims15
An apparatus for guiding a coated material strip through a dryer, said apparatus comprising:
- a plurality of guide elements being disposed in the dryer so that the plurality of guide elements are equally spaced from each other, said plurality of guide elements each having a gas-permeable guide face which faces an underside of said coated material strip;
- and
- means for supplying a gas to said plurality of guide elements so that a gas stream passes through each of said gas-permeable guide faces and supports said coated material;
- a drying gas line through which a drying gas is supplied to said dryer, and wherein said common supply line is different from and is not associated with said drying gas line;
- and
- a common supply line;
- wherein each of said plurality of guide elements includes a duct or a supply tube which receives said gas, and said plurality of guide elements are all connected to said supplying means via said common supply line.
An apparatus for guiding a coated material strip through a dryer's aid apparatus comprising:
- a plurality of guide elements being disposed in the dryer so that the plurality of guide elements are equally spaced from each other, said plurality of guide elements each having a gas-permeable guide face which faces an underside of said coated material strip;
- and
- means for supplying a gas to said plurality of guide elements so that a gas stream passes through each of said gas-permeable guide faces and supports said coated material;
- wherein each of said plurality of guide elements includes a manifold having passage openings therein through which said gas passes, a jacket of sintered glass which has a level polygonal face which faces the underside of said material strip, first sliding seals attached to said manifold which holds said jacket at a distance from said manifold, and a protective jacket which encloses said jacket except for said polygonal face.
