Abstract:

An apparatus for the precision positioning of electrostatic pinning means. The electrostatic pinning means, which significantly improves pinning of a thermoplastic polymeric film cast upon a moving surface, by electrostatic force, is precisely positioned, in relation to an extrusion means and the moving surface, by means of the precision positioning apparatus. The apparatus includes a frame moveable in vertical and horizontal directions. The apparatus further includes the pinning means and support means, connected to the frame, for holding the electrostatic pinning means. Horizontal and vertical adjusting means comprising horizontal and vertical actuating means connected to horizontally and vertically moveable means responsive to the horizontal and vertical actuating means, respectively, are connected to the frame to permit separate horizontal and vertical movements to precisely position the electrostatic pinning means. Horizontal and vertical precision control means are additionally provided, on the moveable frame of the apparatus, to insure that no skewing occurs during horizontal and vertical movements actuated by said horizontal and vertical adjustment means.
