IPC: B29C48/525
Filed: 2000-06-14
Granted: 2002-01-21
Abstract: An apparatus and method for continuously reducing the viscosity of molten moldable polymeric material uses shear vibration under extensional flow to cause shear thinning and/or disentanglement. One or more station treatment cavities are defined by a gap composed of two closely separated surfaces in relative motion with each other at given speed and/or submitted to relative oscillations, with given frequency and amplitude to produce a shear deformation on the molten moldable material and a controlled variation of the gap dimension. The surface have a contour profile of ribs and/or bumps and/or grooves over which the molten moldable material can flow and/or can be dragged and/or is being pushed through and/or pumped through. The treatment cavities have an inlet through which the molten moldable material can pass into, and an outlet through which it can exit each treatment cavity.
