ABSTRACT:
A spreading conveyor comprising an endless air-permeable laterally stretchable spreading band, endless air-permeable supporting band means within the path of the spreading band, and a suction box within the loop of the suction band and having a perforated wall in contact with the inner side of the supporting band means along a portion of its path. This arrangement allows a reduction in the wear and deformation of the spreading band, and can operate at higher speeds than common spreading bands that operate without suction means.
