Description

Technical Field

[0001] The invention relates to the technical field of mask production equipment, and in particular to a semi-automatic film-making machine for folding masks. Background Art

[0002] The cloth mask includes a mask body and ear straps on both sides of the mask body. The mask body is made of multiple layers of fabric, such as non-woven fabric. The nose bridge of the mask body is provided with a nose wire, which is a plastic-coated iron core strip with a certain toughness.
