ABSTRACT:
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.
