Title:
TRIPLE-LAYER RUBBER MANUFACTURING APPARATUS AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/056519
Kind Code:
A1
Abstract:
 Provided are a manufacturing apparatus and a manufacturing method with which triple-layer rubber can be manufactured efficiently. This triple-layer rubber manufacturing apparatus is provided with an external nozzle 14 and an internal nozzle 15. The external nozzle 14 has an outer layer mouth 17 which is provided at the distal end in the output direction, and which demarcates an outer layer internal space 16 of flattened rectangular shape having a prescribed length in the output direction, and being relatively wide in the width direction orthogonal to the output direction, and relatively thin in the thickness direction. The internal nozzle 15 has an inner layer mouth 20 which demarcates an inner layer internal space 19 of flattened cuboid shape having a prescribed length in the output direction, having a dimension in the width direction orthogonal to the output direction equal to that of the outer layer internal space 16, and having a dimension in the thickness direction substantially equal to one-third that of the outer layer internal space 16. The inner layer mouth 20 is arranged in a central portion of the outer layer mouth 17 in the vertical direction, in such a way that within the outer layer internal space 16 demarcated by the outer layer mouth 17, the internal space is divided into an outer layer upper internal space 16U and an outer layer lower internal space 16D.
