Abstract
Official abstract text for this publication.
Provided is a method for manufacturing a multilayered interlayer for safety glass that allows for reliable and easy formation of inserted layers having a larger coloring layer. The method for manufacturing includes processes for respectively delivering, from a first and a second extruding machine, thermoplastic resin composition(s) for the outermost and inserted layers formation in a molten state to the first and second delivering hole of the guide for layer disposition; a process for simultaneously forcing the thermoplastic resin composition(s) to respectively arrive in the outlets for the outermost and inserted layers formation through the flow paths for the outermost and inserted layers formation; and a process for extruding the thermoplastic resin composition(s) for the outermost and inserted layers formation as a multilayer film in a condition where the thermoplastic resin composition for the inserted layer formation is disposed between the thermoplastic resin compositions for the outermost layers formation.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a multilayered interlayer for safety glass having a first and a second outermost layers and an inserted layer disposed between the first and the second outermost layers, said method using an apparatus configured for manufacturing the multilayered interlayer for safety glass, said apparatus comprising: a first extruding machine for delivering a thermoplastic resin composition for the outermost layer formation for forming the first…
