Abstract
A continuous press has two rotatively driven endless conveyor belts forming opposed, substantially linear spans defining a pressing zone, press platens applying pressure through these traveling spans to work carried therebetween, and anti-friction means being interposed between the platens and the spans. Such a press is improved in that the anti-friction means is formed by a multiplicity of endless loops of rotatively unpowered roller chains forming a bed interposed between the platens and the belt spans, the roller chain spans extending longitudinally with respect to the belt spans and being transversely packed together, but each chain being individually free to travel independently with respect to the others and to the belt span. The chains are formed so as to not have a continuous link gap so that the overall path is free from transverse interspacing.
