Respiratory protective device or face mask hygiene product, a method for the manufacture of reinforced textile part, nonwoven fabric part or their combination part, and a filter

A method for the manufacture of a reinforced textile part, nonwoven fabric part or their combination part (11), characterised in that in the method:

• wherein the part to be reinforced (11) comprising textile, non-woven fabric or both of these, is partially separated from a web (1200, 1205) of textile, non-woven fabric or both by a die cutting step before a moulding step, so that the part to be reinforced (11) remains in a material connection with the web (1200, 1205) of textile, non-woven fabric or both, such that a portion of a perimeter or circumference of the part to be reinforced (11) is not die cut from the web (1200, 1205), wherein the partial separation of the part to be reinforced (11) from the web (1200, 1205) is carried out by one or more cutting parts (105, 107) implemented in the mould (100);
• wherein said part to be reinforced (11) is placed into said mould (100) while stretched and wherein said stretching is maintained at the same time as a frame (12), which encircles the part to be reinforced (11), is moulded directly onto said part to be reinforced (11) in the same mould (100) containing said part to be reinforced (11) by means of an injection moulding process, wherein the stretching is carried out by pre-tensioning the part to be reinforced (11) before closing the mould (100), and by using the mould (100) to ensure that the pre-tensioning is maintained when the mould (100) closes, such that after the injection moulding step, the part to be reinforced (11) along with the injection moulded frame (12) encircling the part to be reinforced (11) is transferred by the web (1200, 1205) moving across the opened mould (100).
