A system and method for producing a co-filled product. A center layer is fed through a center channel of a die face and an outer layer is fed through an outer layer of a die face. The center channel is coupled to a fluid control device which controls the flow of the center layer. The position of the fluid control device is determined by the location of a cutting blade located downstream from the die face. In one embodiment the fluid control device is synchronized to ensure that when the product is cut by the cutting blade the cutting blade does not cut through the center layer.
