Rollback point U1、U2Place receives yarn 14 by idle stroke impeller 26,28 from another impeller 26,28 of respective guide yarn
(Fig. 1), in idle stroke section TLPeriod accordingly moved in idle stroke (that is in idle stroke section TLPeriod phase
Should ground do not guide yarn) impeller 26,28 therefore i.e. corresponding idle stroke impeller 26,28 calculates constant theoretical com-pensation angle speed
Spend VC。
In following step 106, based on constant theoretical com-pensation angular speed VCIt is calculated or determined in idle stroke section
The first subinterval TL1The overcompensation angular speed V of period idle stroke impeller 26,28OC。
In step 108, the first subinterval T in timeL1Period is with overcompensation angular speed VOCDrive idle stroke impeller
26、28.The motor of this idle stroke impeller 26,28 moved by correspondingly being manipulated from control device 38s in idle stroke
30 are carried out.
In another step 110, in idle stroke section TLDirectly then the first subinterval TL1The second subinterval TL2
Period is by idle stroke impeller 26,28 from overcompensation angular speed VOCRegulation is to idle stroke impeller 26,28 reciprocating next
Rollback point U1、U2The previously given work angular speed V at placeW, so as in reciprocating next rollback point U1、U2Sentence pre-
First given work angular speed VWYarn 14 is received from another impeller 26,28 of guiding yarn with idle stroke impeller 26,28.
Preferably last for repeating steps noted above 102 to 110 or 104 to 110 for previously given target line
Journey distance HSBy yarn 14 on bobbin 16.
If previously given target stroke distance HSThan normal travel HNIt is narrow, then currently without the impeller of guiding yarn 14
26th, 28 (=idle stroke impellers) must be poor come offset angle by higher rotary speed.When rotating complete one week, when selected
The target stroke distance H selectedSIt is chosen to than foregoing normal travel HNWhen narrow, impeller 26,28 is due to its three-vaned structure
Therefore mode is accelerated to overcompensation angular speed V three times altogetherOCAnd it is braked to work angular speed VW.Can in industrial application
To carry out this process with described 500 times per minute or higher frequency.
In order that idle stroke impeller 26,28, that is in two impellers 26,28 in idle stroke section TLPeriod does not just have
The impeller for having guiding yarn 14 can be with previously given work angular speed VWAccurately in corresponding next rollback point U1、U2
Place receives yarn 14, idle stroke section T from the impeller 26,28 of guiding yarn 14LThe second subinterval TL2As in idle stroke

Corresponding idle stroke impeller 26,28 (Fig. 2) can be adjusted to work angular speed V with required precisionW.It is preposition in impeller
26th, the stabilization sub stage of 28 relevant work stroke causes, the can in the case where not carrying out speed adaption to impeller 26,28
In rollback point U at the time of wishing1、U2Place carries out yarn and delivered.
Therefore according to the present invention, by by the theoretical com-pensation angular speed V of impeller 26,28CImprove overcompensation angular speed VOCCome
Compensate the stabilization sub stage.The long stabilization sub stage is in spite of beneficial to the operating angle speed that impeller 26,28 is realized with small error range
Spend VW.However, thus caused high overcompensation angular speed VOCIt is required that system has Larger Dynamic.It is therefore advantageous that always with must
The degree wanted keeps stabilization sub stage, i.e. idle stroke section TLThe second subinterval TL2It is smaller because the stabilization sub stage allowed
Compensate angular speed VOCClose to constant theoretical com-pensation angular speed VC.Here, the most narrow available target for yarn installation aiding device
Stroke distances HSOvercompensation angular speed VOCIt is equal under any circumstance or less than constant theoretical com-pensation angular speed VC's
120%th, it is preferably equal to or smaller than 112%.
If the reciprocating target stroke distance H of yarn 14SIt is selected larger than the normal travel of yarn installation aiding device
Distance HN, then impeller 26,28 is in corresponding idle stroke section TLMiddle ratio more slowly moves in its relevant work stage.Also
To the theoretical com-pensation angular speed V of corresponding idle stroke impeller 26,28C, it is fast that the theoretical com-pensation angular speed is used as calculating overcompensation angle
Spend VOCBasis.
Similar to most narrow target stroke distance H that can be previously givenSmin, for most wide or maximum target that can be previously given
Stroke distances HSmaxApplicable is so that overcompensation angular speed VOCNot less than theoretical com-pensation angular speed VC88%.Therefore, it is based on
Normal travel HN, overcompensation angular speed VOCSuch as in theoretical com-pensation angular speed VC- 12% to 12% in the range of fluctuate.In mistake
Compensate angular speed VOCRelative to the theoretical com-pensation angular speed V calculatedCPlussage (=△ V) and selected target stroke away from
From HSBetween ratio can be described as linear curve according to Fig. 4.
In Figure 5, for the normal travel distance H less than yarn installation aiding device 12NThe previously given target line of (Fig. 2)
Journey distance HS, the angle change curves of two impellers 26,28 is exemplarily drawn out on time t for two two-passes.Curve
