Method and apparatus for rubber extrusion

摘要

A rubber component extension method and apparatus in which increase or decrease in rubber extruding rate can be freely adjusted while keeping the sectional shape of the rubber component constant in which the discharge port (21o) of a rubber flow path (21) of a die plate (20) is of a flat shape with a lower section (32) and a higher section (33) and with a height (Ho) varying along a width direction. The extruding speed from the discharge port of the die plate is made uniform at positions along the width direction of said rubber extruded component. <IMAGE>
