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. Des procédés sont divulgués pour séparer une première couche d'un reste d'une feuille intercouche multicouche conique, dans laquelle la feuille intercouche multicouche conique est chauffée, et ensuite la première couche est séparée du reste de la feuille intercouche multicouche conique en tirant la première couche et le reste de la feuille intercouche multicouche conique dans différentes directions, dans une orientation définie, sans que la feuille intercouche multicouche conique se plie ou se déchire.
