ABSTRACT:
The fabric strips of vertical blinds are cleaned using a novel method of apparatus. A strip is laid on an elongate tray and wetted with an appropriate washing liquid, e.g. a detergent solution. The strip is then passed along the tray between two counter-rotating brushes which act to scrub the opposite surfaces of the strip. Downstream of the brushes, the strip is sprayed with a rinse liquid. It then travels over a perforated section of the tray where it is subjected to a low pressure from below by a vacuum box communicating with a wet-dry vacuum. The cleaned, partially dry strips can then be hung to complete drying.
