FIELD: textile paper.
SUBSTANCE: invention relates to paper production, particularly to bases and tapes used in paper production. The base for making endless tape, used in a paper-making machine, contains several separate prefabricated layers, which are covered or impregnated with polymer or rubber-like material. Each of the separate layers can be textile material or textile material covered or impregnated with a resin or rubber-like material. At least one of the layers contains a matrix from reinforcement components. The production method of a base for endless tape production involves the following operations: depositing a coating or impregnating at least one layer, obtaining a crude product with coating or impregnated layer. The layers are then joined and processed, obtaining a multilayer structure, or layers containing matrix of pre-polymer and hardening agent are joined, forming a structure which is processed, thereby obtaining a multilayer structure. The obtained structure is then hardened. Tape for use in paper production consists of several separate layers of prefabricated material, which are impregnated or coated with polymer resin or rubber-like material. The layers are joined with formation of a tape in which one the layers contains a reinforcement component. The production method of the tape involves the following operations: depositing a coating or impregnating with polymer resin or rubber like material, at least one layer from the several prefabricated layers, at least one of which contains a matrix of reinforcement elements, joining the layers with formation of a base and converting the base into endless tape.
EFFECT: invention allows for obtaining tape for paper production, stable along and across the machine.
