Abstract

PURPOSE:To adjust a position to provide a passage control means of a viscous material easily by constituting a passage limiting means of the viscous material of a limiting flight and a ring-shaped component in a manner to almost cross rectangularly in the screw axis direction. CONSTITUTION:An extruder is equipped with a continuous cylinder liner 1 in one line and a screw 3 disposed in said casing pivotally. An introducing inlet 4 for a viscous material such as rubber or the like is opened at the upstream end of a liner. A vent hole 2 is opened on the top surface in the almost middle position of the casing. A limiting flight 5 provided almost crossing rectangularly in the screw axis direction as a passage limiting means of a viscous material and a replaceable ring 6 to be fit in and off on a notch provided on a peripheral surface corresponding with the control flight of the liner are provided just in front of the vent hole. Various kinds of replaceable rings are provided to form different inner diameters when incorporated in the casing, and the difference between the inner diameter (b) of the replaceable ring and the outer diameter (a) of the limiting flight is set as the width of the passage limiting line.
