The present invention relates to a dyed-yarn winding method wherein specified length control operates to wind a specified length of a dyed-yarn y without dyeing specks to a winding package Pw, and then cuts the dyed-yarn to remove a dyed-yarn having dyeing specks and remaining an a dyed-yarn supply package Ps. Since the specified length control prevents that part of a dyed-yarn that has dyeing specks from being wound to a winding package, an operation for removing such a part from the winding package can be omitted.

The textile machine has a cooling fluid circuit for dissipating heat from the heat-emitting parts of the textile machine. The cooling circuit has a coil disposed within an air duct of the textile machine from which the air can be blown to the outside. A longitudinally extending fly suction duct may also be used for cooling the cooling fluid of a cooling circuit used to cool the motor and convertor of the textile machine. The fly duct thus serves to remove heat as well as fly from the machine.

An apparatus for controlling a drive of each one of spinning frames forming a group, to which a conventional roving bobbin exchange operation for exchanging almost exhausted roving bobbins of the spinning frame with full packaged roving bobbins of a bobbin carrier on a supply rail arranged at a position close to and above the corresponding spinning frame by a known automatic apparatus mounted on a carrier which is capable of displacing along a track arranged on a floor of a spinning factory along an alignment of out-end frames of said spinning frames, is applied, wherein during the spinning operation, a residual roving quantity of the roving bobbins of each spinning frame is measured, while detecting a quantity of yarn wound on cops in each spinning frame, and when the above-mentioned measurement of a residual quantity of roving bobbins reaches a predetermined value, a first signal indicating this condition is issued, while the quantity of yarn wound on the cops is measured to detect a suitable condition to start the above-mentioned roving bobbin exchange operation, and when this suitable condition is detected, a second signal indicating this condition is outputted, then a signal calling the automatic apparatus is outputted based upon the logical product of these two signals, and an allowable time for the arrival of the automatic apparatus at a working position close to a particular position and close to the out-end frame of a spinning frame is set, and if the automatic apparatus for exchanging roving bobbins does not arrive at the above-mentioned working position within the allowable time, the drive of the spinning frame concerned is stopped by a means for controlling the drive of the spinning frames which cooperates with the measurement of a residual quantity of a roving bobbin and measurement of a quantity of yarn wound on the cops.

A twister apparatus and method in which filamentary material is wound onto rotating bobbins are provided. A guide rail reciprocates within a range for distributing the filamentary material onto the bobbins, and the guide rail range itself is reciprocated along the height of the bobbins to distribute the filamentary material over a plurality of portions of the bobbins. Means for measuring the yardage of the filamentary material onto the bobbins is provided. Means responsive to a predetermined yardage for determining the presence of the guide rail within one of a plurality of predetermined portions of the bobbins is provided. There is also provided means for discontinuing the movement of the guide rail at a preselected position within the range of reciprocation of the guide rail.

In immediate response to the detection by a yardage counter or the like of a full package condition at the textile machine, the auxiliary ring rail positioning means rapidly moves each ring rail of the machine directly and unidirectionally, from whatever random vertical position it might then occupy, to a preselected doffing position preferably located between and in spaced relation to the opposite ends of the normal path of reciprocatory movement of the ring rail. Upon each subsequently ensuing startup of the machine, the auxiliary ring rail positioning means rapidly reciprocates each ring rail, between the aforesaid preselected doffing position and the lower limit of the rail''s normal path of reciprocatory movement, for an adjustably variable time period sufficient to ''''tie-in'''' the yarn ends.

The invention concerns a spinning machine having a spindle with which to rotate a yarn package, a winding apparatus to wind the yarn on the package, and drafting rolls to feed the yarn to the winding apparatus. According to the disclosed method, the winding down of the yarn on the package is achieved by reversing the rotation of the spindle relative to the spinning direction. according to the disclosed device, a spacer ring is employed which is fixed to the spindle, and which has an upper and a lower hollow, a protruding edge, and substantially sharp edges which aid in cutting the yarn.
