PURPOSE:To reduce the size of the titled apparatus and decrease the heat- generation in a bearing, by using a twisting roller having suction pipe in the roller, and placing the bearing supporting the roller in the suction pipe. CONSTITUTION:The suction pipe is inserted into and fixed to the insertion hole 3 of the supporting table 1, and the bearing 7 is inserted into and fixed to the constricted part of the pipe 5. The rotary shaft 9 is inserted and fixed to the bearing, and a porous roller 12 is fixed to the protruded end of the shaft 9. The bearing 7 is cooled with air flow sucked through the suction port 5a by the action of the suction pipe 5, and the heat generated in the bearing 7 by the high-speed revolution of the porous roller 12 is deprived to effect the prevention of temperature rise of the bearing 7. |
