    摘要: A device and method for winding conical bobbins with yarn withdrawn at constant speed from individual spinning units, and comprising: a deflecting roller, or similar element, which is connected to and moved backwards and forwards by a swinging plate element 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 wherein yarn is drawn into the storage position and is then released from this storage position, (i.e. returned). This returning operation releases the yarn from its storage position and replaces it (returns it), to its normal feed path; two proximity sensors positioned to define the regular range of swing of the flat yarn storage and return element; an electronic control unit which receives an electrical signal or several electrical signals provided by the proximity sensors 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 bidirectional drive unit; a bidirectional drive unit which inclines the conical bobbin axis, so displacing the diameter of effective contact between the conical bobbin and the drive roller, in order to vary the yarn winding speed and so return the storage swing to within the range of values corresponding to regular storage.

    摘要: A yarn storage and return device for yarn being wound on a conical bobbin driven at a constant speed. The device comprises a lever system for speed. The device comprises a lever system for storing and returning the yarn and for regulating and monitoring the amount of stored yarn. The yarn is drawn into the storage position by an arm of the lever system and is then released (i.e. returned) from this storage position. This returning operation releases the yarn from its storage position and replaces it (returns it) to its normal feed path. The device also comprises a transducer, and electric comparator, and an electric processor control unit to convert, compare and process an electrtic controlling signal to activate a drive source. The drive motor actuates a tensioning element which affects the storage operation of the device. The device further comprises a bidirectional drive unit to obtain a variation in the average yarn winding speed to restore the storage operation to a predetermined range of values.

This changes the tension on the yarn to return the storage swing to within the regular range. If irregular swing persists, a bidirectional drive is activated to displace the contact between the bobbin and drive roller to restore the storage swing to within the regular range of values.

    摘要: A device and method for winding conical bobbins with yarn withdrawn at constant speed from individual spinning units, and comprising: a deflecting roller or similar element, which is connected to and moved backwards and forwards by a swinging flat element for yarn storage and accumulation, to compensate the variation in the speed at which the yarn is collected on the conical surface of the bobbin under formation wherein yarn is drawn into the storage position and is then released from this storage position, (i.e. returned). This returning operation releases the yarn from its storage position and replaces it (returns it), to is normal feed path; an electronic or similar yarn tension measurer of known type for measuring the tension values of the yarn being wound and to generate electrical signals proportional to said values; an electrical comparator for comparing said electrical signals with one or more reference signals to generate a control signal when an electrical signal arises which indicates a non-regular yarn tension; an electronic control unit for converting said control signal into a signal which varies the amplitude of the swing motion of a drive source; a drive source which increases or decreases the amplitude of its intermittent drive motion in order to adjust the swing movement of the storage arm to an amplitude which is slightly greater or slightly less than the previous value in order to rapidly restore the yarn tension to within the range of values corresponding to regular tension.
