Abstract (en)
[origin: US2014182600A1] A filtering face-piece respirator 10 that comprises a harness 14 and a mask body 12 that has a pleats 21. The mask body 12 has an indicia 19 located within the pleat 21 in at least a partially non-visible location when the pleat 21 is folded. The indicia 19 is made from a weld pattern and is fully visible when the pleat 21 is unfolded. The fully visible indicia 19 provides an indication to the wearer that the mask body is in its proper unfolded condition. The indicia 19 also includes welded lines that extend normally across the pleat to improve collapse resistance.
