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