Abstract

The invention provides a mask not prone to deformation and a method for manufacturing a mask body. A plurality of fold parts formed by folding the filter paper forming the mask body into a fold shape extend in the left-right direction and are jointed near the periphery of the mask body and the center of the mask body in the left-right direction.

Description

technical field [0001] The invention relates to a method for manufacturing a mask and a mask main body. Background technique [0002] Patent Document 1 discloses a filtering face-piece respirator having at least one laterally extending reinforcement member formed of s-shaped or tri-folded pleats permanently joined by welding or the like.
