METHOD AND APPARATUS TO FORM CARPET OF MINERAL FIBERS

摘要

FIELD: threads formation of mineral fibers. SUBSTANCE: method to form primary sheet of carpet of mineral fibres on movable pervious base is exercised using fibers transfer on base by air stream or corresponding means. Air stream is adjusted so, that to minimize pressure difference on formation base. There is description of apparatus for realization of the method. EFFECT: increased productivity, decreased production costs.
