Abstract:
An apparatus for the continuous filtration and flow of molten thermoplastic polymer from a melt source to a shaping apparatus. The apparatus is characterized by the employment of a melt reservoir whose level is regulated by a level control means. Melt flow to the shaping apparatus is regulated by the level control means which controls the flow rate from the melt source as a function of the level in the melt reservoir.
