Title:
MASK MANUFACTURING METHOD AND MASK MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/172254
Kind Code:
A1
Abstract:
[Problem] To provide a technique which can apply stretch properties to ear straps in a production line while preventing the ear straps from wrinkling. [Solution] A joined sheet (211) is obtained by joining sheets (121a, 121b), which form a mask body section, to both sides of a sheet (141) for forming ear straps. A stretching device (610) is constituted by a pair of a first gear roller (620) and a second gear roller (630). The first gear roller (620)(second gear roller (630)) has a stretching section (620b)((630b)) and gripping sections (620a)((630a)) provided on both sides of the stretching section (620b)((630b)). Teeth (protrusions)(621)((631)) and grooves (recesses)(622)((632)), the teeth (protrusions)(621)((631)) and the grooves (recesses)(622)((632)) extending in the circumferential direction, are formed alternately in the axial direction on the outer peripheral side of the stretching section (620b)((630b)). The stretching device (610) stretches the sheet (141) by means of the stretching sections (620b, 630b) while the sheets (121a, 121b) are gripped between the gripping sections (620a, 630a).
