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.

Abstract: A container blank forming machine is disclosed which allows an operator to quickly form container blanks in accordance with operator selected container type and dimensions. The preferred machine includes a framework having a flat stock support bed, selectively activatable and shiftable cutting heads, a computer, and a touch screen monitor. In operation, the computer causes the monitor to display a selection of container types to which the operator responds with a selection and specific finished container dimension data. The operator then enters flat stock into the machine which automatically cuts and scores the flat stock to form a completed container blank in accordance with the container type selection and dimensions provided by the operator.
