Title:
多層溶融合成樹脂供給装置
Document Type and Number:
Japanese Patent JP5741193
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a multilayer synthetic resin supply device capable of preventing or suppressing a stringiness phenomenon in which an inside molten synthetic resin to be enveloped in an outside molten synthetic resin exists in filaments even in a place where the resin should not exist as much as possible without causing the other problem such as excessively reducing the mechanical strength of the device.SOLUTION: A sub-discharge path (22) communicating with an upstream end of a main discharge path (18) is formed into a form that contains a cylindrical large diameter upstream part (24) and a small diameter downstream part (26) and an interception member (58) is formed into a form that contains a columnar-shaped large diameter upstream part (62) corresponding to the large diameter upstream part of the sub-discharge path and a small diameter downstream part (60) corresponding to the small diameter downstream part of the sub-discharge path.
