Abstract
A continuous belt press has upper and lower platens defining a horizontal gap. Upper and lower upstream drums and downstream are rotatable on the frame about respective horizontal drum axes at the upstream and downstream ends of the gap. Upper and lower endless steel belts spanned over the respective upper and lower drums each have a working stretch supported by respective upper and lower sets of rollers on the respective platens. Each belt has a pair of edges projecting transversely past the respective rollers and at least one of the drums of each of the belts has a substantially cylindrical central region of a predetermined central diameter bearing through the respective rollers on the working stretch of the respective belt and a pair of edge formations of smaller diameter than the central-region diameter lying outside the central region and in engagement with the edges of the respective belt.
