摘要： A sliver piecing unit 80 includes three sets of separable rollers 804 and 844, 806 and 846, and 808 and 848 for nipping a sliver S1 fed from a consumed can to a spinning machine. A throttling nozzle 870 is arranged between the second and third sets of rollers 806 and 846, and 808 and 848. The draft ratio between the first and second sets of rollers 804 and 844, and 806 and 846 can be varied between 1.0 and 2.0. A sliver feed unit 70 includes a separable first and second roller 702a and 702b for feeding a sliver S2 from a full can to the piecing unit 80 so that the slivers S1 and S2 are combined. The draft ratio between the first and second sets of rollers 804 and 844, and 806 and 846 is controlled to obtain combined slivers of a thickness corresponding to that of a single sliver. A nipping belt 884 and nipping roller 886 are provided at the outlet from the third set of the rollers 808 and 804 for obtaining a rubbing movement in the combined slivers. A breaking element 802 is provided at the inlet to the first set of the rollers 804 and 844 to break the first sliver S1 after the completion of the piecing operation.

摘要： When a full bobbin signal from a counter CCM counting the number of rotations of the front roller (3) is output, the control element (28) outputs a signal directed to the control motor (M2) of a unit (29) for reciprocating a bobbin rail (10). As a result, the rotation of the control motor (M2) is combined with the rotation of a differential gear (14 ) connected to the main motor (M1), so that a reciprocating movement of the bobbin rail (10) after the full bobbin state is obtained which is faster than that obtained during a usual taking up operation of the roving, which causes the roving to be wound on the bobbin in a much coarser state than usual. A limit switch (LSP) detects a predetermined desired position of the bobbin rail (10), and the control element (28) outputs a signal directed to the unit (29), whereby the main motor (M1) and the control motor (M2) are stopped.

摘要： An apparatus for preventing an unwinding of a roving end from a full package roving bobbin during the transportation thereof. This apparatus is constructed in combination with the transportation mechanism formed in the known doffing mechanism or known overhead roving bobbin transportation system, in a condition such that a part of the constitutional mechanical elements of such known transportation mechanisms are utilized as a part of the constitutional mechanical elements of the apparatus according to the present invention. In the apparatus of the present invention, a pressing member is utilized for applying pressure against the peripheral face of the winding portion of each roving bobbin while this bobbin is rotating, and therefore the free end of the roving is firmly attached to the above-mentioned peripheral face of the roving bobbin. Consequently, any possible problems due to an unexpected unwinding of the roving can be effectively prevented.

摘要： When a residual amount R of a roving required to make a bobbin full at a desired stopping position A of the bobbin rail which moves upwardly is smaller than the amount (4.times.L) corresponding to remaining four layers of the roving for a normal winding process, a desired amount Q is calculated as the residual amount R divided by 4. The switching of the roving during the downward movement of the bobbin rail is done when the amount of the roving from the top end of the bobbin rail is equal to the desired spinning amount Q. This operation is repeated until a full bobbin amount is detected by an encoder, and the flyer frame is stopped.
