The specific embodiment
At each winding head place, yarn 2 is extracted and is wound into out cross winding bobbin, promptly so-called winding bobbin 3 from spinning bobbin 1 (being so-called spool).The reel line segment of a large amount of spinning 1 of cross winding bobbin.
Again around during, yarn 2 extends and is subjected to monitoring to find the yarn fault owing to passing optical profile type or capacity-type electronic yarn clearer 4.
If yarn clearer 4 is found fault, then cut off yarn 2.Separate the fault line segment, once more the end of a thread that produces is interconnected afterwards.This is for example undertaken by splicer 5.
Winding bobbin 3 remains on can be on the bobbin bank 6 that axle 7 pivots as follows, that is, between the whole on-stream period of bobbin, on take up roll 8, winding bobbin 3 is driven by friction winding bobbin 3 by its peripheral support.Take up roll 8 is provided with unshowned drive motor, and this drive motor can drive take up roll 8 along coiling direction (shown in arrow) and debatching direction.
Cut off yarns 2 or yarn when disconnecting owing to other reason at yarn clearer 4, the end of a thread that is connected on the winding bobbin still is wound up on the winding bobbin, rests on the somewhere on these winding bobbin 3 peripheries then.The end of a thread that is connected to spinning bobbin 1 remains in the thread tension device 9.For line is connected once more, two the end of a thread to be connected must be placed in the wire-connecting device, for example be placed in the splicer 5.
Therefore, can be transported to around the following tension disk 10 that axle 11 pivots from the yarn under working of spinning bobbin 1 to thread tension device 9 operations.Can be transported to winding bobbin 3 around the suction nozzle 12 that axle 13 pivots.In order to find the end of a thread, and it is rolled and extracts out, drive winding bobbin 3 on the contrary by take up roll 8 and coiling direction in the periphery of winding bobbin 3.Suction yarn gripper 12 is pivoted back to shown position together with the yarn of extracting out from winding bobbin (that is the so-called yarn of going up) and yarn is inserted in the splicer 5 after capturing the end of a thread.
In order to regulate suction effect according to suction nozzle of the present invention, covering 14 is associated with the tubulose protrusion 13 that also forms rotating shaft, by these covering 14 adjustable openings cross sections and so and the intensity of scalable suction air-flow and the suction effect of suction nozzle 12.
