Abstract
A respiratory mask comprises a body portion that is formed from an air-permeable material and that has at least one component, for example an exhalation valve, secured to the body portion by a printed patch of adhesive. In one embodiment, the mask is a fold-flat mask (1) comprising panels (3, 5, 7) each of which is formed from superposed layers of air-permeable material. An exhalation valve (13) is secured to the center panel (3) by a patch of adhesive that is printed on the outer layer of the panel. Use of a printed patch of adhesive enables components to be accurately secured to the mask body at high speeds.
