摘要
The protective masks (1) are produced by perforating a continuous web material. To this end, each protective mask can be separated from the other masks along perforation lines (1.3), and then wound into a roll. The protective masks have transverse perforation lines (1.4) which are opened at the time of use to form openings into which the ears can be inserted and thus secure the protective mask to the face.
