The specification describes an improved humidifier pad and a method of making the pad. The pad comprises a fibrous layer provided with means which substantially eliminate the flow of water picked up by the fibrous layer along the length of the pad so that when the pad is in use on a rotating drum, the water that is picked up is held in the pad for vaporization rather than flowing back downwardly to the pickup point.

A humidifier pad provided with liquid flow inhibiting junctures for inhibiting the flow of liquid along the pad, said humidifier pad comprising a resilient plastic reinforcing layer and a fibrous layer being secured to the reinforcing layer by heat seals extending across the entire width of the pad

A humidifier pad provided with liquid flow inhibiting junctures for inhibiting the flow of liquid along the pad, said humidifier pad comprising a resilient plastic reinforcing layer and a fibrous layer being secured to the reinforcing layer by heat seals extending across the entire width of the pad and forming said junctures which are spaced along the length of the humidifier pad; the reinforcing layer being perforated to permit the passage of air therethrough to the fibrous layer, the fibrous material in the junctures being compressed and of increased density relative to the fibrous material between the junctures as a result of the heat sealing and being of sufficiently high density to substantially eliminate the flow of picked up water across each zone.
