Description

This subclass covers machines and methods for cleaning textile products, carpets, rugs, sacks, hides, and similar flexible materials through mechanical action or fluid pressure rather than chemical treatment. It includes equipment for beating, brushing, rubbing, or spraying these articles to remove dirt, dust, and contaminants. The subclass also encompasses apparatus for turning inside-out flexible tubular articles (such as stockings or gloves) and hollow textile structures, a specialized mechanical operation distinct from conventional cleaning processes.
