LAMINATING INTERLAYER EXPANDING APPARATUS

摘要

LAMINATING INTERLAYER EXPANDING APPARATUS An apparatus for expanding a laminating interlayer is disclosed. The apparatus includes structure for feeding a heated web of laminating interlayer material to a conical member. A stretching of the web occurs between the feeding structure and the conical member. The web is cooled on the conical member. The apparatus also includes a controllable drive associated with the conical member which is controlled in response to measured width and thickness of web to maximize the yield from the web being stretched.
