Patent ID: 8545205

Claim:
A system for making PET objects comprising: means for reacting a first PET precursor and a second PET precursor to produce a PET melt; an acetaldehyde reduction unit including a vacuum section with a screw element line through the vacuum section; means for flowing said PET melt to a valve having at least two outlets; means for flowing said PET melt from at least one of said at least two outlets to at least one distribution manifold, and each of said at least one distribution manifold having at least two distribution lines; means for controlling individually a mass flow of the PET melt in each of said at least two distribution lines independently of the other of said at least two distribution lines; and at least two means for forming said PET objects from said PET melt, the at least two means for forming said PET objects each interconnected with a different one of the at least two distribution lines, the means for flowing said PET melt configured to provide highly dependent thickness control with a constant pressure into the at least two means for forming said PET objects, wherein the means for controlling individually the mass flow of the PET melt is located between the at least one distribution manifold and the at least two means for forming said PET objects, wherein the means for flowing said PET melt to said valve having at least two outlets includes a pump, and the means for controlling individually a mass flow of PET melt is configured to modulate the pressure in the at least two distribution lines; wherein when the pressure drops at the means for controlling individually the mass flow of the PET melt, the speed of the pump is increased and when the pressure rises at the means for controlling individually the mass flow of the PET melt, the speed of the pump is decreased, and thus the means for controlling individually the mass flow of the PET melt is configured to control a speed of the pump.
