Abstract: A duckbill mask includes a mask upper side and a mask lower side. A manufacturing process includes: respectively performing edge folding and press sealing on an upper nose edge on the mask upper side and a jaw edge on the mask lower side, and using a double-way staggered cutting process to add a nose bridge while folding the upper nose edge; and overlapping the mask upper side and the mask lower side, then performing press sealing on convex edges of the mask upper side and the mask lower side by using a staggered opposite arrangement method, and using a double-way staggered cutting process to add an ear belt while performing press sealing on the convex edges. In the multi-line machining process, multi-line edge folding and press sealing of all layers of materials, overlapping and then finished product cutting are performed, whereby two duckbill masks are manufactured at a time.
Abstract: The invention relates to a method and a device for making absorbent cores used in disposable hygiene pads, the method or device comprising three steps: (A) suctioning of wood pulp fibers mixed with super absorbent polymers into a net structure on a base tissue to form an absorbent core; (B) compressing and embossing absorbent material; and (C) shaping of the absorbent core. The method of the current invention can be used for making different kinds of absorbent pad products. While increasing the tear strength of the product, the method realizes and simplifies the process of making both the absorbent material and the hygiene pad utilizing the absorbent material on the same manufacturing line, and reduces the cost of making the absorbent pads. The absorbent core made by applying the method of the current invention has a new structure formed by super absorbent polymers and wood pulp fibers, wherein the structure enables the super absorbent polymers to be evenly distributed in between the wood pulp fibers.
