<p>Granulate prodn. machine, comprising a belt conveyor on which wax is deposited, is associated with a scraping knife which has projections along its cutting edge to separate the wax layer longitudinally as it is scraped off the belt. The projections may be formed by wires stretched across a notched blade. Used esp. for making granulate for extrusion, e.g. of wax candles.</p> |
