A multi-part headband attachable to a face mask blank and a method of attaching the same. The mufti-part headband has a unit length corresponding to the distance between the attachment locations as measured along a surface of the face mask blank or along an axis intersecting the attachment locations, to facilitate material handling and attachment using high speed manufacturing equipment. The headband material is positioned along the headband path and attached at the left and right headband attachment locations. At least one longitudinal score line is formed in the headband material extending generally along the headband path, whereby the at least one longitudinal score line defines a multi-part headband. The face mask blank may comprise a molded cup-shaped face mask, a Hat folded face mask or a variety of other face mask constructions.

Serre-tête à parties multiples pouvant être fixé à une structure de masque facial, et son procédé de fixation. Le serre-tête à parties multiples a une longueur unitaire correspondant à la distance entre les sites de fixation mesurés le long d'une surface de la structure de masque facial ou le long d'un axe coupant les sites de fixation, afin de faciliter la manipulation matérielle et la fixation au moyen d'un équipement de fabrication à grande vitesse. Le matériau du serre-tête est placé le long de l'emplacement destiné au serre-tête et fixé aux points de fixation de gauche et de droite du serre-tête. Au moins une entaille de pliage longitudinale est formée dans le matériau du serre-tête, s'étendant généralement le long de l'emplacement prévu pour le serre-tête, ce qui fait que la ou les entailles de pliage longitudinales définissent un serre-tête à parties multiples. La structure de masque facial peut comprendre un masque facial moulé en forme de bol, un masque facial plat plié ou différents autres types de configurations de masque facial.
