OPERATION CONTROL OF FINE SPINNING FRAME EQUIPPED WITH ROTARY RING AND DEVICE THEREFOR

摘要

PURPOSE:To eliminate troubles such as end breakage in starting and stopping of spinning, by supporting a rotary ring by plain support system in starting and stopping of fine spinning frame and holding the rotary ring in a stationary state without specifically setting a brake. CONSTITUTION:A bearing housing 2 of static air pressure is fixed to a ring rail 1, a supporting member 3 is held through an O ring 4 inside and rotary ring 7 is rotatably immobilized to the top and inside of a rotor 5 in an integrated way with the rotor 5. In starting, compressed air is not sent to the bearing of static air pressure until number of revolutions of spindle reaches a given number of revolutions and a rotor is made to act in the same manner as that of a supporting member of plain support type. In suspension, at a point of time when number of revolutions of the spindle reaches a given number of revolutions, pressure of compressed air is reduced and the rotor 5 is made to act in the same manner as that of a rotor of plain support type.
