Provided are an apparatus and a method for manufacturing a multilayered interlayer for safety glass that allows reliable and easy formation of inserted layers having a larger coloring layer. The manufacturing apparatus 1 for manufacturing the multilayered interlayer for safety glass having a first outermost layer, an inserted layer, and a second outermost layer laminated together, wherein an outlet for the inserted layer formation 14 is provided between outlets for of the first and the second outermost layers formation 9 and 10 on an outlet side of a guide for a layer disposition 4, the outlets for the first and the second outermost layers formation 9 and 10 and the outlet for the inserted layer formation 14 have a shape of a slit, the dimension L, in a slit shape in the width direction, of the outlet for the inserted layer formation 14 is set smaller as compared with the dimension K, in a slit shape in the width direction, of the outlets for the first and the second outermost layers formation 9 and 10, the thickness of the slit is set smaller with increasing proximity to the end on at least one end of the outlet for the inserted layer formation 14 having a shape of a slit, and a metal mold for extrusion 5 is connected in a subsequent stage of the guide for a layer disposition 4.
L'invention concerne un appareil et un procédé de fabrication d'une couche intermédiaire de multiplexage pour verre de sécurité, pouvant former de manière fiable et facile une couche d'insertion comme une couche colorée plus grande. Une sortie formant une couche insérée (14) est disposée entre la première et la seconde sorties formant couche les plus extrêmes (9 et 10) du côté de la sortie d'un guide de disposition de couche (4). La première et la seconde sorties formant couche les plus extrêmes (9 et 10) et la sortie formant une couche insérée (14) ont des fentes. La taille, dans le sens de la largeur en fente (L), de la sortie formant une couche insérée (14) est inférieure à la taille dans le sens de la largeur en fente (K) de la première et de la seconde sorties formant couche les plus extrêmes (9 et 10). Dans la fente de la sortie formant une couche insérée (14), en outre, la fente est rendue plus étroite vers la portion d'extrémité. Un moule d'extrusion (5) est relié à la phase arrière du guide de disposition de couche (4).
