    摘要： Apparatus for continuously filtering molten polymer comprising: an arbor seated in a fixed support, the arbor having inlet and outlet ports for respectively receiving contaminated and discharging filtered melt, the ports communicating with openings in a pair of housings rotatably mounted on the arbor; a plurality of filter pod assemblies outwardly of and mounted on the rotatable housings, each assembly having a filter for contaminated melt and intake and discharge openings intermittently alignable with the ports on rotation of the housings to position a clean filter in the path of the contaminated melt and to remove the filter from the path when blocked with contaminants; passages associated with the inlet and outlet ports of the arbor and the housings for gradually establishing a flow of melt into a clean filter as it is rotated into filtering position; and thermally dilatable seal between the rotatable housings and the arbor to seal the housings and the arbor during the filtering of contaminated melt by a filter element of a filter pod assembly and to establish a clearance between the housings and arbor as a result of thermal expansion of the thermally dilatable seal to allow rotary movement of each housing to replace a blocked filter with a clean filter. A continuous filter process is provided by operation of the above apparatus.

    摘要： A process for forming discrete, shaped interlayer blanks comprising extruding thermoplastic melt into an endless, distortable straight-sided sheet having a gradient color band along one side, the melt forming the region of the sheet laterally of the color band extruding at a greater thickness than that forming the portion containing the color band, stretching the side of the sheet containing the region formed from the greater thickness melt more than the other side while extrusion continues to shape the sheet into an arcuate form of substantially uniform thickness having different radii along each edge, the edge of greater radius being on the side formed from the greater thickness melt, quenching the sheet to set the polymer, advancing the shaped sheet to a cutting station and cutting shaped quadrilateral sections out of the sheet having the gradient color band along one longitudinal side to form the blanks.
