ABSTRACT:
An endless belt type of conveyor for small flat workpieces (chips) provides a series of pockets on a perforate belt, each pocket adapted to support a chip during conveyance through a zone wherein high velocity air jets are directed against the chip. The pockets are formed by facing pairs of series of "H" or "I" shaped crossbars connected between a spaced-apart pair of roller chains. The perforate belt is formed by a Teflon (polytetraflouroethylene) coated fiberglass screen (alternatively silicon rubber) supported by the H crossbars. This construction permits the pockets to move readily around the sprockets about which the roller chains are wound.
