  • System for metering and film packaging of bitumen and like materials
    Patent number: 4306657
    Abstract: A system for metering and film packaging of bitumen and like materials that are solid at room temperature and molten liquid when heated. The packaging film is thermoplastic, having a melting point not exceeding the temperature of molten bitumen. The material of the packaging film in liquid form is compatible with bitumen without deleteriously affecting the characteristics of the bitumen. In the system, bitumen in a hot molten state is pumped at a filling station into empty molds that are lined with release material. The fluid bitumen is metered at the filling station to supply a predetermined quantity in each mold. The filled molds are conveyed through a lengthy cooling station that may include a water bath and after a suitable time, e.g. 2 to 4 hours, the bitumen solidifies into slabs.
