摘要： A mould tunnel (5) for the continuous, step by step moulding of a foamed plastics block is divided into two functionally distinct zones, namely a front zone (9) and a rear zone (10). A metering hopper (32) and sliding gate (13) provide for charging the front zone with a predetermined quantity of expandable plastics beads. An ejector wall (7) defining the front end of the front zone is connected to a cross-head (28) on a jack-screw (29) and may be driven to and fro within the front zone in consequence of motorised reversible rotation of the screw. The walls, floor and roof of the tunnel, the sliding gate and the ejector wall are slotted or perforated and jacketed, with the jackets of the rear zone being distinct from those of the front zone. The jacketing is such that, under independent control, steam under pressure or vacuum may be applied to the front zone through its side walls, the front zone may be connected to atmosphere through its floor, the ejector wall and gate, and vacuum may be applied to the rear zone through its floor, walls and roof. In use a still soft moulded section is held in the rear zone by the application of vacuum thereto. Beads are charged into the front zone; the ejector wall is moved slightly to compress the charge of beads; air is then flushed from the front zone by flowing steam through it, which also warms and softens the beads; vacuum is then applied to the front zone to extract condensate and residual air; steam under pressure is then applied to the front zone to expand the beads and bond the expanded mass to the section in the rear zone; steam is discontinued to the front zone and vacuum applied to quickly reduce pressure therein; vacuum is broken to both zones and the newly moulded section is ejected into the rear zone to displace the prior moulded section from the tunnel into a curing chamber; and the process is repeated.

摘要： A rotary screen for separating fines from expanded polystyrene foam particles comprises a rotary cylindrical screen (15) with its axis substantially horizontal, material to be screened is fed into one end of the screen, a shroud covering an upper part of the screen has its walls sealed to the screen by bristled brush wipers (24), a fan (27) draws air from the shroud, causing air to flow into the screen through its unshrouded lower part, and exhausts same with entrained fines into a filter bag, the residual particles are caused to flow along the screen for discharge at the other end by contact with a stationary Archimedean screw (20) within and co-axial of the screen. The discharged material is received in a vented mixing chamber wherein it is mixed with fresh expandable beads, and fed directly to a foam moulding machine by a second fan drawing air through the mixing chamber.

摘要： A method of making an expanded plastics foam block section and uniting it with a prior made, or partly made, section comprising the steps of charging a mould space of which one end is defined by a surface of the prior section with expandable plastics beads, initiating the expansion and fusion of the beads to create a cohesive but largely unexpanded mass of beads, obtruding the prior section into the mould space to compress a zone of the cohesive mass adjacent to the said one end, increasing the temperature and pressure in the mould space to complete the expansion and fusion process and to compress the end zone of the prior section to bring its end substantially to its unobtruded position, lowering said pressure and temperature, and ejecting the newly made block section from the mould space. Apparatus for performing the method is also disclosed.
