Abstract: In a cleaning system for cleaning venetian blinds, the blinds are stretched with their slats extending vertically on a carrier belt that is mounted to rotate about longitudinally separated drive and idler assemblies. One run of the carrier belt forms a station for loading and unloading of the blinds, and the other run of the carrier belt passes through successively arranged chambers in which both sides of the blinds to be cleaned are sprayed with washing liquid followed by various rinse solutions, whereafter the blind is passed through a drying chamber in which hot air is blown to effect drying. The vertical arrangement of the slats of the blind enable the washing and rinse liquids to drain rapidly and substantially completely so that the energy required for drying is reduced.
