Abstract
Apparatus (10) is provided for cleaning of dirty, clogged sandpaper, particularly large, industrial size sandpaper belts (190) used in furniture making operations. The apparatus (10) includes a drum (58) adapted to support a belt (190), together with blasting means (16) adjacent the drum (58) for creating a stream of particulates directed toward a portion of the belt (190) for cleaning purposes. Positioning means (18) is also provided for selectively changing the relative orientation of the blasting means (16) and the belt (190) in order successively clean different portions of the belt (190). Preferably, a laterally reciprocal nozzle (108) is employed for creating the particulate stream, and the belt (190) is intermittently shifted via a pneumatic mechanism (158) to present successive portions of the belt (190) for cleaning thereof. Dislodged material and dust is conveyed from the apparatus (10) through a port (42), whereas the particulate cleaning media is collected in a lower hopper (50) for recirculation to the nozzle (108 ).
