<P>PROBLEM TO BE SOLVED: To provide kneading equipment which employs cantilever structure of supporting only the proximal end side of a screw shaft by a bearing, and nonetheless suppresses contact of the distal end of the screw shaft with a barrel. <P>SOLUTION: The kneading equipment 1 includes: the screw shaft 2 for kneading material; and the barrel 3 in which the screw shaft 2 may be inserted. A contact prevention means 13 configured to prevent the screw shaft 2 from contacting with the barrel 3 in the midst of the rotation by a magnetic force is provided between the screw shaft 2 and the barrel 3. Besides, preferably, the kneading equipment 1 is an extruder equipped with two screw shafts 2, and it is preferable that the distal end of the screw shaft 2 is a free end, whereas the proximal end of the screw shaft 2 is freely turnably supported. <P>COPYRIGHT: (C)2012,JPO&INPIT |
