Abstract:
A method of cleaning the surfaces of guiderolls used in treating and processing cloth is comprised of the steps of attaching lengths of guide cloths, which are provided with wiping surfaces on both sides, to lengths of the cloth being processed so that the guide cloth and the cloth being processed are continuously passed over the guiderolls. Dampening at least one or both of the guide cloth and the guiderolls so that the guiderolls are wiped clean as the guide cloths pass over them. Preferably, the guiderolls are reversed from the normal direction of rotation to assist in the cleaning operation.
Abstract:
In an apparatus for coating foils or bands on one side with solutions of high viscosity as the foils or bands are passed through a gap, the surface of one wall of which is wetted with the solution of the gap is formed by a rotatably mounted support roller for the band which is to be coated and the other wall surface is formed by a cup which is adapted to the circumference of the roller and which is suspended via a weight loaded lever system in such a manner that it is three-dimensionally displaceable on it.
