Device for filling a mould with prefoamed plastics granulate - comprises a reservoir, a feed line and an injector to aspirate the granules

摘要

Device for filling a mould with pre-foamed plastics beads has a supply reservoir and a feed line connecting the reservoir with an injector by means of which the beads are sucked up. Between the reservoir and the injector there is a pneumatic controlling appts. built into the feed line whose membrane-sealed pressure chamber is connected via a transverse duct, with a flow duct in the feed line. An electric switch is associated with the outer surface of the membrane which cuts off the injection-air supply when there is excessive pressure in the pressure chamber.
