    摘要: This invention relates to a device for regulating the winding seed in the formation of cross-wound conical bobbins where the yarn is withdrawn at constant speed from the rotor spinning unit by a lever system able to displace the friction drive band of the drive roller for the conical bobbin under formation, in order to vary the average resultant value of the varying winding speed during each double stroke of the yarn guide element. Said lever system is operated by a two-direction rotary drive source which is activated when a linear position element, associated rigidly with the yarn storage element, senses by known means that abnormal storage swings persist.

    摘要: A device and method for winding conical bobbins (29) with yarn withdrawn at constant speed from individual spinning units, and comprising: a deflecting roller (5), or similar element, which is connected to and moved backwards and forwards by a swinging arm (4) which by storing and returning the yarn compensates for the different speeds at which the yarn is collected on the conical surface of the bobbin under formation; two proximity sensors (8, 9) positioned to define the regular range of swing of the yarn storage and return arm (4); an electronic control unit (10) which receives an electrical signal or several electrical signals provided by the proximity sensors (8, 9) when the yarn storage and return swings stray outside the regular range in order to generate, when said signals occur, an electrical control signal which activates a pressure variator; a pressure variator arranged to increase or decrease to a limited extent the pressure on a disc yarn tensioner (7) in order to adjust the tension of the yarn being wound to a value slightly higher or slightly lower than its previous value so as to return the storage swing to within the range of values corresponding to regular storage; a bidirectional drive unit (12, 15) which if non-regular storage swing persists is activated to incline the axis (25) of the conical bobbin (29), so displacing the diameter of effective contact between the bobbin and drive roller (27) to consequently obtain a variation in the average yarn winding speed in order to restore the storage swing to within the range of values corresponding to regular storage.

    摘要: A device and method for winding conical bobbins (24) with yarn withdrawn at constant speed from individual spinning units, and comprising a deflecting roller, peg, or similar element (5), which is connected to and moved backwards and forwards by a swinging arm (4) which by storing and returning the yarn with swing movement compensates for the different speeds at which the yarn is collected on the conical surface of the bobbin (24) under formation. Said deflecting roller (5) varies the length of the yarn path so as to stabilise the tension of the winding yarn being deposited at a practically constant value during the entire cycle defined by the travel of the yarn guide element from a position corresponding to one end of the bobbin to its return into said position.
    The value at which the tension of the yarn is stabilised during its winding onto the conical surface derives from the elastic action generated by a spring (6) or similar element. The position of the deflecting roller is determined at every moment by an analog or digital transducer (7, 36).
    The value of said store must fluctuate within a range extending between preset limits. If a storage value arises which does not lie within the preset range, the transducer generates an output signal the intensity of which is such as to activate, by means of a central unit (8), a drive source (9) which is arranged to vary the extent of elastic deformation impressed on the spring (6) or like elastic element. Said variation corrects the tension of the yarn being wound to a value which is slightly different from the preceding value so as to rapidly return the fluctuating storage to within the preset range.
