Manufacturing process and apparatus for duckbill mask

A manufacturing process for a duckbill mask, using a multi-line machining process, a staggered opposite arrangement method, a double-way staggered cutting process and a double slow-release wheel machining process, wherein the manufacturing process comprises:

• using a multi-line mask machining apparatus, and comprising the following steps:
• firstly, sandwiching a melt-blown fabric between two layers of non-woven fabrics for compounding, and then respectively performing edge folding and press sealing on an upper nose edge on a mask upper side and a jaw edge on a mask lower side;
• secondly, using the double-way staggered cutting process to add a nose bridge while folding the upper nose edge;
• thirdly, overlapping the mask upper side and the mask lower side, then using the staggered opposite arrangement method to perform press sealing on convex edges of the mask upper side and the mask lower side, and using the double-way staggered cutting process to add an ear belt while performing press sealing on the convex edges;
• and
• fourthly, cutting and overlapping a finished product, then taking the mask upper side and the mask lower side as single masks.
