ABSTRACT:
An apparatus and method for producing sheets of bitumen in which a layer of liquid bitumen is deposited on a steel belt conveyor and is solidified to form a continuous web. The web is stripped from the conveyor and passes downwardly by the action of gravity to a cutting assembly which cuts the web into lengths to form sheets. The sheets are then stacked upon a discharge conveyor and are adapted for packaging.
