Abstract: A molding device (10) for molding three-dimensional products (76) from a mass of foodstuff comprises a molding roller (16) and a filling device (18). The molding roller (16) has a molding surface with at least one mold cavity (44) which is delimited by a mold cavity (44) opening. The filling device (18) has a dispensing mouth (36) and a pump. The dispensing mouth (36) and the mold cavity (44) opening each have, viewed in the direction of the movement path, a front edge and a rear edge which is situated at a fixed distance thereof. A position-determining device determines the position of the front edge of the mold cavity (44) opening with respect to the front edge of the dispensing mouth during the movement of the mold cavity (44) opening and the dispensing mouth (36) with respect to each other. A control unit controls the pump on the basis of the position-determining device during the movement of the mold cavity (44) opening and the dispensing mouth (36) with respect to each other.
