摘要： The invention relates to a process and apparatus for producing a colored band in an extruded thermoplastic sheet. In the process, a probe is inserted in a sheet extrusion die manifold and a colored melt is injected into the polymer melt such that a sheet with an encapsulated colored band is obtained.

摘要： Plasticized polyvinyl butyral sheet optionally containing a gradient color band is formed by continuously extruding a sheet having a predetermined region across its width formed from melt issuing from a die at an increased mass flow rate in comparison with other portions of the melt forming the rest of the sheet and then forwardly distorting such sheet immediately after forming by preferentially stretching the side containing the predetermined region to form an arcuate shape of substantially uniform thickness. Arcuately shaped sections are then cut from the sheet to form discrete, shaped interlayer blanks having improved thickness uniformity and dimensional stability providing improved performance when used in laminated safety glass.
