Document Type and Number:
Japanese Patent JP7142858
Kind Code:
B2
Abstract:
To be insufficient of a kneading action since a flat screw is formed by one or more spiral grooves having a smooth curve from an outer peripheral edge toward a center, and a material tends to flow in a laminar flow state in a spiral groove.SOLUTION: A delivery device has a rotating mechanism, a screw rotating by the rotating mechanism, and a barrel. The screw has a first screw groove and a second screw groove on a screw surface facing the barrel.
