Abstract
A layer of granules is deposited onto a conveyor belt and then heated and pressed to form a final product (e.g., floor covering). The layer is deposited from a funnel having a bottom outlet. Disposed across the outlet are a rotary sizing roll which forms a first gap with the belt, and an inclined guide plate which forms a second gap with the sizing roll. Granules flow through the second and first gaps, and then onto the belt. The second gap is larger than the first gap so that excess granules are supplied to the first gap, thereby assuring that no voids are created in the deposited layer. The guide plate is oscillated to facilitate a back-flow of excess granules to resist the possibility of excess granules being forced through by the sizing roll.
