METHODS AND DEVICES FOR MECHANICAL SEPARATION OF MULTILAYER TAPERED INTERLAYERS
20260042285 · 2026-02-12 · ·

Processes are disclosed for separating a first layer from a remainder of a tapered multilayer interlayer sheet, in which the tapered multilayer interlayer sheet is heated, and thereafter the first layer is separated from the remainder of the tapered multilayer interlayer sheet by pulling the first layer and the remainder of the tapered multilayer interlayer sheet in different directions, in a defined orientation, without the tapered multilayer interlayer sheet wrinkling or tearing.
