  • FIG. 5A and 5B show respectively continuous bands bearing cuts or lines of weakening with a view to making the masks in accordance with the embodiments shown in FIGS. 2C and 4B.
  • the assembly of the mask is constituted by a single cut effected in sheet of foamed material, the cut permitting, in a single operation and forexample by means of a punch of obtaining a yoke comprising a central part 1 and 2 rounded ends each provided with an opening 2 and 2 whereby there are two formed marginal handles 3 and 3' which permit the positioning and fixing of the mask on the face of the wearer by putting in place the handles behind the ears.
  • the mask is cut from a continuous sheet or band 4 having a succession of longitudinal folds 5, 5'.
  • each mask is provided with marginal cuts'7 and 7' forming respective openings 8, 8', after removal, as shown in FIG. 2C, of the cut-out pieces 9 and 9.

  • the lateral handles 12, 12' may be spread out by opening of the folds 5, 5'.
  • the handles 12, 12' can be adjusted behind the ears and the central face of the mask 13 can be spread out by opening of the folds as far as possible or as desired.
  • the folds are of course held at weld or sticking locations l0, 10, 11, 11' so that the front face 13 of the mask taking up a desired shaped to conform to the portion of the face which it is to cover.
  • a continuous band having longitudinal folds is used, the width of the band being calculated to correspond to the length or large side of the mask. This band is cut transversely to form single cutouts each corresponding to a mask in which the folds appear parallel to the short sides.
  • the mask is cut from a sheet or band folded along an edge 20.
  • this folded sheet there is made two marginal cuts 21, 21 of generally triangular but curved shape, the base of each of which is defined by the line of the fold.
  • the mask 22 is unfolded into two symmetrical halves 23, 23 and the tabs 24, 24 defined by the cutting are also unfolded to form two lateral handles 25, 25' (for positioning over the ears permitting the fixing of the front face or central part of the mask 22 onto the face.
  • the mask is cut as in the preceding example from a sheet or band which is folded along an edge 30, the band being cut into lengths along transverse cut lines 31, 31'.
  • Each length cut-out has itself a marginal cut 32, 32 intended to separate from the central part of the mask the tabs 33, 33 which will form the lateral handles 34, 34.
  • a cut is effected at each end of the length to enable the separating of triangular pieces 35, 35'.
  • the two halves of the folded sheet are fixed along the edges 36 and 36 co-incident with the edges of the cut outs 35, 35.
  • the folded band is treated by automatic machine and the bands are made of thermo-plastics material and/or thermal formable or weldable material and the cuts and/or welds are effected by the thermal cutting and welding means which are cutting and/or welding bars.
