Abstract
Provided are a method of producing ear loop members for masks and a device for producing ear loop members for masks with which it is possible to inhibit a reduction in the production efficiency of the masks. The method of producing ear loop members (4) for masks includes a conveyance step (S2), a tension adjustment step (S3), and a forming step (S4). In the conveyance step (S2), a sheet (U1) having high stretchability in a high-stretch direction (DH) is conveyed in a conveyance direction (C10) running along the high-stretch direction (DH) while tension is applied in the high-stretch direction (DH) to the sheet (U1). In the tension adjustment step (S3), the tension in the conveyed sheet (U1) is adjusted. In the forming step (S4), ear loop members (4) are formed by cutting the sheet (U1) after the tension adjustment.
