ABSTRACT:
A continuous belt press has a frame having horizontally extending and vertically spaced upper and lower plates defining a horizontally extending gap having an upstream end and a downstream end and vertically spaced upper and lower upstream drums rotatable on the frame about respective horizontal drum rotation axes at the upstream end. Vertically spaced upper and lower downstream drums are rotatable on the frame about respective horizontal drum rotation axes at the downstream end and upper and lower endless steel belts are spanned over the respective upper and lower drums and each have a working stretch lying between the plates and a return stretch. Upper and lower sets of rollers are engaged between the working stretches and the respective plates. The drums are driven to advance the belts to move the working stretches horizontally in a transport direction to displace a workpiece in the direction through the gap. The downstream drums have a diameter which is greater than that allowable by the tension in the respective belts as they move around the downstream drums and the upstream drums have a diameter which is substantially less than the diameters of the respective downstream drums and that would not be usable on the downstream drums because it would exceed the permissible belt tension. Drives are provided for rotating the downstream drum with a predetermined torque and for rotating the upstream drum with a torque equal to between 0% and 75% of the predetermined torque of the downstream drums.
