Abstract
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 apparatusfor 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 formationis provided between outlets for of the first and the second outermost layers formationandon an outlet side of a guide for a layer disposition, the outlets for the first and the second outermost layers formationandand the outlet for the inserted layer formationhave a shape of a slit, the dimension L, in a slit shape in the width direction, of the outlet for the inserted layer formationis 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 formationand, 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 formationhaving a shape of a slit, and a metal mold for extrusionis connected in a subsequent stage of the guide for a layer disposition
