Patent ID: 7556487

Claim:
An apparatus for making a filled chewing gum product, comprising: an extruder comprising: an extruder head defining a chamber for receiving a molten gum composition and including a die defining a die orifice through which the molten gum composition is forced from the chamber under pressure so as to extrude a rope of gum from the die orifice; a center filling mechanism having a filler tube extending through the die orifice; and a feed passage extending through the extruder head and connecting with the filler tube for feeding a filling through the filler tube, such that the gum rope extruded through the die orifice is formed to have a channel filled with the filling; a rope sizer structured and arranged to receive the gum rope from the extruder and to reduce the cross-sectional size of the gum rope and to shape the gum rope to have a non-round cross-sectional shape with a greater dimension in a width direction than in a height direction; a cooling tunnel structured and arranged to receive the gum rope from the rope sizer and to cool the gum rope, the cooling tunnel comprising a series of individual belt conveyors each extending substantially horizontally and parallel to a machine direction along which the gum rope is advanced and spaced apart from one another in a vertical direction such that the belt conveyors substantially lie in a vertical plane, the belt conveyors including an uppermost belt conveyor and a lowermost belt conveyor each traveling in the machine direction and at least one intermediate belt conveyor, wherein each belt conveyor travels in a direction opposite to the immediately prior belt conveyor, and wherein the gum rope is threaded in a serpentine fashion through the cooling tunnel such that the gum rope is carried along one of the belt conveyors traveling in the machine direction and then along subsequent ones of the belt conveyors, finally exiting the cooling tunnel from the lowermost belt conveyor; and a cutter structured and arranged to receive the gum rope from the cooling tunnel and to cut the gum rope into discrete gum pieces each having a cavity filled with the filling.
