摘要： A method and an apparatus for automatically controlling the winding tension of the roving in a bobbin lead roving machine is disclosed. The mean bobbin winding diameter D e , bobbin r.p.m. N B and the flyer r.p.m. N F are measured automatically for one or more operating spindles, and a mathematical equation (N B /N F - 1) x D B = K representative of winding conditions for the roving is solved by automatic operation based upon the above measured values. When the value K thus obtained exceeds a preset control limit, the bobbin r.p.m. is decreased or increased automatically for correcting the value K towards its central setting for automatically correcting the winding tension of the roving.

摘要： Described is a bobbin lead roving machine in which target r.p.m. values for the bobbin (1) are found in advance for each of arbitrarily selected numbers of the layers of the roving taken up on the bobbin (1) and are stored in a micro-computer (A) there r.p.m. values are compared to actual r.p.m. values for respective ones of said arbitrarily numbers of the layers, and compensation is made automatically for any offsets resulting from such comparison for causing the r.p.m. of the bobbin (1) to be within a control limit, in a manner that the take-up tension placed on the roving is kept constant during spinning from the beginning until the end of winding on the bobbin for producing roving of uniform weight (with a constant weight/unit length).

摘要： A truck (39) carrying plural rows of vertically placed empty bobbins (38) is conveyed to one end of the machine base of the flyer frame, the empty bobbins of the first row are taken out of the truck and conveyed to an empty bobbin supply device (41) on the machine base, the truck (39) is moved a predetermined distance by an intermittent feed unit (40), and fresh full yarn packages (43) from the flyer frame so far placed on the conveyor are transferred by a full yarn package transfer device to said truck (39) at the positions from which the empty bobbins have been removed. The operation of taking out empty bobbins (38) from the truck (39) and supplying them to the empty bobbin supplying device (41) on the machine base and the operation of transferring the full yarn packages (43) to said truck (39) are performed in an alternate fashion.
