The multi-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 flat folded face mask or a variety of other face mask constructions.
