Title:
BIAXIAL EXTRUDER
Document Type and Number:
WIPO Patent Application WO/2016/002333
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a biaxial extruder that can be used effectively even in uses such as straining by being configured to be capable of increasing the pressure for extruding a material from the material-discharging opening in the compressing section while limiting increases of load power and generation of heat in the material in the hopper section. The biaxial extruder is configured so that the size of the lead angle (β2) of a screw blade (21) in the compressing section (12) is set to be larger than the size of the lead angle (β1) of the screw blade (21) in the hopper section (11) and so that at least two windings of the screw blade (21) are disposed in the position of the compression section (12).
