Abstract

A method for making face masks includes: advancing continuously a longitudinal sheet material that can be divided into a plurality of mask sheets each of which has two opposite longitudinal ends and two opposite transverse ends; cutting the sheet material at intervals to form the mask sheets; providing a plurality of strips each of which has two longitudinally opposite strip ends and each of which is folded to form a pleat between the two strip ends thereof; and bonding the two strip ends of each of the strips to one of the opposite transverse ends of a respective one of the mask sheets to form an ear loop. A structure of the face mask is also disclosed.

Claims

1. A method for making face masks, comprising:

advancing continuously a longitudinal sheet material that can be divided into a plurality of mask sheets each of which has two opposite longitudinal ends and two opposite transverse ends;

cutting the sheet material at intervals to separate the mask sheets;

providing a plurality of strips each of which has two longitudinally opposite strip ends and each of which is folded to form a pleat between the two strip ends thereof; and

bonding the two strip ends of each of the strips to one of the opposite transverse ends of a respective one of the mask sheets to form an ear loop.

2. The method of claim 1, wherein, during the bonding of the two strip ends of each of the strips, each of the strips is disposed along one of the transverse ends of a respective one of the mask sheets, with the two strip ends thereof being proximate to the two longitudinal ends of the respective mask sheet, respectively.

3. The method of claim 2, wherein the bonding of the two strip ends of each of the strips is conducted after the sheet material is cut into the mask sheets.

4. The method of claim 2, wherein the bonding of the two strip ends of each of the strips is conducted before the sheet material is cut into the mask sheets.

5. The method of claim 1, wherein the strips are made of an elastic non-woven fabric.

6. The method of claim 1, wherein the pleats of the strips are formed by heat-pressing.

7. The method of claim 1, wherein the strips are provided from a sheet which is cut and divided into the strips and which is folded to form a Z-shaped pleat before being cut.

8. The method of claim 1, further comprising the step of stacking a plurality of fabric layers to form the sheet material.

9. A face mask comprising:

a mask sheet, and a pair of ear loops, each of said ear loops being made of an elastic strip and having two opposite strip ends bonded to said mask sheet, and a pleat between said strip ends.

10. The face mask of claim 9, wherein said elastic strip is made of an elastic non-woven fabric.
