发明名称 Pulp mill apparatus
摘要 A method and an apparatus is used for forming airlaid articles such as diapers, sanitary napkins and the like. The apparatus includes an anvil drum with die cavities formed therein. The die cavities have foraminous bottom walls for drawing a stream of air-entrained fibrous fluff therethrough. A first material layer is laid on the anvil drum for covering some of the die cavities and is then deformed into the cavities. After a belt with opening corresponding to the die cavities has been laid on the first layer for protecting the sealing areas from fluff, an air stream with fibrous fluff is drawn through the first layer and through the foraminous bottom walls, thus pulling the first layer into the die cavities and causing the fluff to be deposited in the cavities. A second material layer is placed on the deposited fluff and glued or crimped to the first layer. A die-cutting roller then cuts the airlaid articles into the desired shape before the articles are removed from the anvil drum.
