An air barrier or skirt apparatus (50) for a surface treating machine having a brush (16) chamber and a rotatable brush substantially disposed within the brush chamber. The air barrier or skirt apparatus (50) is disposed adjacent either end of the rotatable brush (16) and extend from the brush chamber to a surface to be cleaned. The air barrier or skirt apparatus (50) comprises an inner flexible member (52) and an outer flexible member (86). The inner flexible member (52) and the outer flexible member (86) are coupled to each other at predetermined attachment regions (64, 66, 68, 100, 102, 104), with the predetermined attachment regions defining first and second dimensions on the inner (52) and outer (86) flexible members, respectively. The first dimension of the inner flexible member (52) is less than the second dimension of the outer flexible member (86), so that when the inner and outer flexible members (52, 86) are coupled to each other at the predetermined attachment regions (64, 66, 68, 100, 102, 104) the inner flexible member (52) is formed into a non-planar configuration. A method of fabricating such a skirt apparatus (50) is also disclosed. |
