Abstract: An integrated unit for producing double-layered spherical products (23) in two rows on a belt conveyor (25) under it is disclosed. The length of the integrated unit is aligned with the traveling direction of the conveyor (25) in order to reduce the space needed on both sides of the conveyor (25). The integrated unit includes a filling feeder (15) and a casing feeder (17) for feeding a filling (5) and a casing (9) such that the feeders (15) and (17) are arranged opposite each other. A space between the feeders (15) and (17) of the integrated unit is provided with vane pumps (29A) and (29B) and a pair of double nozzles (13A) and (13B), which are positioned in the center of the integrated unit. The vane pumps (29A) and (29B) pump the corresponding materials (5) and (9) from the corresponding feeders (15) and (17) to the corresponding double nozzles (13A) and (13B). Each double nozzle extrudes the filling (5) and the casing (9) in a form of a double-layered elongated product.
