摘要： A device for producing a yarn from a staple fiber, comprising a pair of twisting rollers rotatable in the same direction and arranged in a manner confronting each other with a small gap between peripheral surfaces thereof, a spinning zone being formed on the upper surfaces of the twisting rollers in the vicinity of confronting portions of the rollers for condensing staple fibers to form a fiber bundle, at least one of the twisting rollers being provided with a plurality of grooves on at least one part of a peripheral surface thereof; a first duct for supplying a separated staple fiber, provided with an outlet opening disposed closely above the spinning zone; a second duct for sucking air, provided with an outlet opening disposed to confront the outlet opening of the first duct while intervened by the spinning zone so that the air is sucked from the spinning zone through a channel formed by the grooves; and means for withdrawing the fiber bundle from the spinning zone in a direction substantially along an axis of the twisting rollers to form a yarn.

摘要： An apparatus for controlling the roving winding speed in a roving frame, in which a roving position detecting unit (56) detects central positions of vibration of the roving (55) in the vertical direction at a position between a front roller (8) of the drafting device and a flyer top (12) through a plurality of photoelectric sensors, an average central position of the vertical vibration of the roving (55) is computed from the values measured by the roving position detecting unit (56), and a quantity of correction of the rotation number of a bobbin (30) is computed from a deviation between the average central position and an aimed value for controlling the roving winding speed and a correction coefficient. A correction signal is generated corresponding to the correction quantity, and the rotation number of the bobbin (30) is regulated based on the correction signal.
