Pressure gauge 86 is configured between solenoid valve 81 and operating room 76, the pressure to the compressed air supplied to operating room 76 It is detected and is exported to air-pressure controlling portion 83.Detected value of the air-pressure controlling portion 83 based on pressure gauge 86, control electricity Magnet valve 81,82 is so that above-mentioned pressure becomes instruction pressure.

The time change of the above-mentioned pressure based on the variable portion 71 of air pressure is illustrated using Fig. 7.In the figure 7, just Beginning pressure is P0.Instruction pressure is sequentially input air-pressure controlling portion 83 from the grade of unit control unit 15.In moment T0, if from list The P1 that first grade of control unit 15 is for example inputted more than P0 is used as instruction pressure, then air-pressure controlling portion 83 opens solenoid valve 81, solenoid valve 82 is closed, and above-mentioned pressure is increased, it is reached P1.In moment T1, if P2 of the input less than P1 is used as finger Show pressure, then air-pressure controlling portion 83 closes solenoid valve 81, opens solenoid valve 82, and declines above-mentioned pressure, makes its arrival P2.In moment T2, if also input has other instruction pressure, air-pressure controlling portion 83 controls solenoid valve 81,82 in the same manner, And change above-mentioned pressure.In this way, the pressure of the compressed air supplied to operating room 76 is adjusted at any time by the variable portion 71 of air pressure For the arbitrary pressure of below the pressure Pmax of the compressed air of supply source.

The pressure of composition more than, bearing sleeve 73 and the compressed air supplied to operating room 76 accordingly, is being rolled up The rotation direction of principal axis movement of bobbin Bm.That is, if 73 above-mentioned pressure of bearing sleeve increases, to the stent close to bobbin stent 56 The side movement of main body 58, if above-mentioned pressure reduces, is moved to the side away from rack body 58.Do not supplied to operating room 76 To the state of compressed air, or supplied the compressed air of the low pressure for the degree that brake-shoe 75 is not contacted with rack body 58 Under state, rack body 58 is unlatched, and can be rotated freely through relative to bearing sleeve 73.In addition, at this time, rack body 58 are exerted a force by the compressed air of spring 77,79 and above-mentioned low pressure via axis 78 to winding spool Bm sides.Thus, spool Bm quilts are wound Remain to rotate freely.

On the other hand, if supplying the compressed air of high pressure to operating room 76, bearing sleeve 73 is to 58 sidesway of rack body Dynamic, brake-shoe 75 is contacted with rack body 58.Thus, produce the frictional resistance between brake-shoe 75 and rack body 58 and brake The rotation of rack body 58, so that the winding spool Bm and package 100 that are rotated integrally with rack body 58 slow down.Make package The size of the brake force of 100 rotational deceleration, with the size pair of the frictional force produced between brake-shoe 75 and rack body 58 Ground change is answered, so that the size of above-mentioned frictional force and the pressure of the compressed air in operating room 76 accordingly change.

As described above, can be by the variable portion 71 of air pressure, by the pressure of the compressed air supplied to operating room 76 The arbitrary pressure being adjusted at any time below the pressure of the compressed air of supply source.Package is acted on therefore, it is possible to change at any time The size of 100 brake force.

In addition, the detected value based on pressure gauge 86, by air-pressure controlling portion 83, control solenoid valve 81,82 so as to The pressure for the fluid that operating room 76 supplies becomes instruction pressure.Therefore, it is possible to adjust above-mentioned pressure as instruction pressure, so that The brake force for acting on package 100 can be changed.

In addition, instruction pressure is sequentially input air-pressure controlling portion 83 from the grade of unit control unit 15, so as to indicate pressure Be sized to package 100 moderating process in change at any time.Package is acted on therefore, it is possible to suitably be changed according to situation The size of 100 brake force.

As described above, the brake apparatus 53 of present embodiment is by making from the variable portion 71 of air pressure to making room The pressure change of the compressed air of 76 supplies, it is arbitrary to become so as to freely control the pressure in operating room 76 Pressure.If using above-mentioned brake apparatus 53, when 100 deceleration is wrapped can with the circular velocity of package 100 change Deng the corresponding appropriate deceleration of situation, for example, can suppress package 100 quality reduce.As one example, below, Generate broken yarn in the case of when connecing yarn, to make package 100 slow down control illustrate.

As described above, winder unit 2 possesses yarn accumulation portion 13, when yarn is connect, yarn is accumulated in also by consumption The yarns Y of accumulating part 13, so as to carry out connecing yarn when continuing the coiling action of yarns Y.But connect yarn failure in contingency In the case of, there is the worry for the yarns Y exhaustion for being accumulated in yarn accumulation portion 13, therefore package 100 is slowed down when connecing yarn, and into Row suppresses the control of the consumption of the yarns Y in yarn accumulation portion 13.

At this time, the winding speed of package 100 to be made rapidly slows down as far as possible, if but excessively sharp slow down, because of traversing Slip between roller 52 and package 100 and damage the yarn on the top layer of package 100, or produce skips and cause quality is wrapped Reduce.Therefore, below, the pressure in operating room 76 is controlled by brake apparatus 53, so that package 100 suitably subtracts Speed is not so that package quality reduces as far as possible.

The a series of control of unit control unit during generation broken yarn etc.

Hereinafter, using Fig. 8 and Fig. 9 to subtracting comprising when producing broken yarn etc., package 100 based on unit control unit 15 The a series of control of speed processing illustrates.

First, unit control unit 15 is in the state of package 100 is contacted with traversing roller 52, driving drum drive motor 62 and rotate traversing roller 52, and be wrapped 100 winding yarn Y.Above-mentioned low pressure is supplied to the operating room 76 of checking cylinder 60 Compressed air, package 100 is not braked.In other words, 100 circular velocity and the circular velocity substantially phase of traversing roller 52 is wrapped Deng.In addition, unit control unit 15 is controlled cylinder drive motor 42 and rotates yarn accumulation roller 41, and yarn is deposited The amount of stockpiling of the yarns Y in product portion 13 remains in right amount.Hereinafter, using the yarn winding action under the state as being commonly wrapped about moving Make.The circular velocity of package 100 and traversing roller 52 when being commonly wrapped about acting is, for example, 1500m/min.

During action is commonly wrapped about, because producing broken yarn, cutting yarn, replace spool etc., and make yarn feeder 11 and yarn In the case that yarns Y between line accumulating part 13 becomes unconnected state, as shown in figure 8, being produced from the output of yarn clearer 36 disconnected The signal of yarn etc., and input unit control unit 15 (S101).At this time, the winder unit 2 of present embodiment is while carry out described later Yarn processing is connect while drawing yarns Y from yarn accumulation portion 13 and continuing yarns Y to the winding of package 100.But at this time, to deposit Product is in the inexhausted mode of the yarns Y in yarn accumulation portion 13 and connects yarn processing concurrently, and 100 and traversing roller 52 are wrapped into exercising Slow down and make the slack-off deceleration processing (S102) of the winding speed of yarn.

To slowing down, processing is described in detail.Carrying out connecing yarn processing while continuing yarns Y to the volume of package 100 Around when, unit control unit 15 needs to make in a manner of the yarns Y for being accumulated in yarn accumulation portion 13 is not exhausted package 100 to be rolled with traversing Cylinder 52 slows down, and makes the winding speed of yarns Y temporarily slack-off.In particular, it is desirable to make the week of package 100 and traversing roller 52 Speed is for example decelerated to 300m/min from 1500m/min.

Unit control unit 15 reads in the target circular velocity of traversing roller 52, and cylinder drive motor 62 is controlled and is started The deceleration of traversing roller 52.At the same time, unit control unit 15 reads in the instruction pressure slowed down when starting, variable to air pressure 71 output indication pressure of portion.Air-pressure controlling portion 83 is compressed air to operating room 76 based on the instruction pressure being transfused to Supply, start package 100 deceleration.

In the moderating process of package 100 and traversing roller 52, unit control unit 15 calculates the peripheral speed of package 100 at any time The difference (slippage) of the circular velocity of degree and traversing roller 52.The circular velocity of traversing roller 52 is based on drum rotation speed sensor 63 Traversing roller 52 of the testing result with being pre-stored within ROM etc. diameter and calculate.The circular velocity of package 100 is based on package The testing result of the testing result of rotation speed sensor 61 and drum rotation speed sensor 63 and control.In further detail and Speech, when reducing speed now, obtains testing result and the inspection of drum rotation speed sensor 63 of package rotation speed sensor 61 Survey the ratio of result.In addition, for the ratio when, it is assumed that be wrapped 100 circular velocity it is equal with the circular velocity of traversing roller 52, base The deceleration control of slippage has been accounted in the ratio.

Fig. 9 is that the deceleration for representing package 100 starts the time of the pressure of the later compressed air supplied to operating room 76 The chart of one example of change.Initial stage, i.e. slow down start before above-mentioned pressure P0 be above-mentioned low pressure.Deceleration processing starts Above-mentioned pressure afterwards is higher than P0.In deceleration processing procedure, unit control unit 15 will indicate pressure to air-pressure controlling portion 83 It is sequentially output, controls the variable portion 71 of air pressure at any time so that slippage converges on defined scope.That is, if package 100 subtracts It is fast excessively then to reduce instruction pressure and die down so as to slow down, if the deceleration of package 100 is insufficient, instruction pressure is improved so as to subtract Speed enhancing.By the variable portion 71 of air pressure, above-mentioned pressure is adjusted to the arbitrary pressure of below Pmax at any time, therefore can Carry out above-mentioned control.

Indicating the size of pressure can also change according to the amount of thread of package 100.In the case where package 100 is relatively light, If the brake force based on brake apparatus 53 is excessive, there is the worry that package 100 is exceedingly decelerated.As described above, unit control 15 output indication pressure of portion processed is so that slippage converges on defined scope.Therefore, in the case where package 100 is relatively light, instruction Pressure integrally diminishes (with reference to (a) of Fig. 9).On the contrary, in the case where package 100 is heavier, instruction pressure integrally increases (with reference to figure 9 (b)).Based on the instruction pressure, air-pressure controlling portion 83 changes above-mentioned pressure so that above-mentioned amount of thread is fewer, effect It is smaller in the brake force of package 100.

Carry out the control unit control unit 15 of the slippage of the above while to yarns Y to package 100 winding speed Desired value whether is reached to be judged.If the circular velocity of the package of unit control unit 15 100 reaches desired value, its peripheral speed is maintained Degree.If the circular velocity of package 100 does not reach desired value, continue deceleration processing.

In addition, even if the exhausted situation for carrying out above-mentioned deceleration processing and also expecting the yarns Y in yarn accumulation portion 13 Under, unit control unit 15 is controlled brake apparatus 53 with cylinder drive motor 62 and package 100 is stopped with traversing roller 52 Only.

In addition, with above-mentioned deceleration processing concurrently, unit control unit 15 carries out connecing yarn processing.Unit control unit 15 is to rolling Cylinder drive motor 42 is controlled, and stops yarn accumulation roller 41.Then, as described above, unit control unit 15 is to connecing yarn Device 33 guides yarn under working Y1 to control yarn splicing device 33 with upper yarns Y 2 and carry out connecing yarn.It is single during this connects yarn processing Also driving drum drive motor 62 makes traversing roller 52 and the rotation of package 100 to first control unit 15, and is drawn from yarn accumulation portion 13 Yarns Y and continue yarns Y to package 100 winding.But at this time, since yarn accumulation roller 41 stops, yarns Y The amount of stockpiling is reduced.

Next, unit control unit 15 is controlled cylinder drive motor 42 and rotates yarn accumulation roller 41, then Secondary beginning yarns Y stockpiling to yarn accumulation portion 13.To make the yarns Y in the yarn accumulation portion 13 of reduction promptly increase as far as possible Add, unit control unit 15 accelerates yarn accumulation roller 41, and fast rotary speed rotation when making it than being commonly wrapped about action (S103).Finally, unit control unit 15 controls cylinder drive motor 62 and accelerates traversing roller 52, makes the winding speed of yarns Y Degree returns to the speed (S104) when being commonly wrapped about action.At this time, the rotary speed of yarn accumulation roller 41, which also returns to, is commonly wrapped about Rotary speed during action.

As described above, in the present invention, in the moderating process of package 100, the pressure that will can be supplied to operating room 76 The pressure of contracting air is adjusted to arbitrary pressure at any time, so as to change the brake force for acting on package 100 at any time.Therefore, Since package 100 contacted with traversing roller 52 and yarn connection and make the state of winding yarn Y package 100 and traversing rolling In the case that cylinder 52 slows down, traversing roller 52 is set to slow down with maximal efficiency while making it follow package 100, so as to contract Small package 100 is poor with the circular velocity of traversing roller 52.Therefore, it is possible to prevent the unfavorable condition of skips, broken yarn etc..

In addition, the yarn between yarn feeder 11 and yarn accumulation portion 13 is set to become unconnected state because of broken yarn etc. In the case of, during carrying out connecing yarn by yarn splicing device 33, the yarns Y for being accumulated in yarn accumulation portion 13 is drawn, so as to continue The formation of package 100.In this case, in the state of the yarn connection between yarn accumulation portion 13 and package 100, to stockpile When the inexhausted mode of the yarn in yarn accumulation portion 13 makes package slow down, if the circular velocity of package 100 and traversing roller 52 , then there is the worry for producing skips, the top layer disorder being wrapped etc. in the difference increase of circular velocity.In the present invention, subtracting in package 100 During speed, the pressure of the compressed air supplied to operating room 76 can be adjusted to arbitrary pressure at any time, so as to Shi Biangeng acts on the brake force of package 100, therefore can easily control the difference of above-mentioned circular velocity, on preventing The unfavorable condition stated.

Further, since package 100 is lighter, acting on the brake force of package 100 can more diminish, therefore can prevent from being wrapped 100 excessive deceleration.

Next, the variation for applying change in the above-described embodiment is illustrated.Wherein, pair with above-mentioned embodiment party There is formula the component of identical composition to mark identical reference numeral, and simultaneously the description thereof is omitted as appropriate.

(1) composition of brake apparatus can also be changed.In Fig. 10, brake apparatus 91 replaces the air of the above embodiment Pressure variable unit 71, and with solenoid valve 87 (supply switching valve of the invention) and supply control part 88.

Solenoid valve 87 is the three-way solenoid valve of Closed type.Solenoid valve 87 is configured at the solenoid valve in the variable portion 71 of air pressure Between 81 and operating room 76.The supply mouth side of solenoid valve 87 connects with the entrance side of the outlet side of solenoid valve 81 and solenoid valve 82 Connect.The exhaust side of solenoid valve 87 is connected with exhaust outlet 85.The cylinder mouth side of solenoid valve 87 is connected with operating room 76.Supply control part The switching (opening and closing) of the on/off of 88 control solenoid valves 87.The opportunity data of the opening and closing of solenoid valve 87 is for example controlled from unit Portion 15 is output.If being powered (on-state) to solenoid valve 87, the supply mouth side of solenoid valve 87 is opened and exhaust side is closed Close, and make compressed air flowing as the arrow of solid line in Figure 10 represents, compression is supplied from supply mouth 84 to operating room 76 Air.If the energization to solenoid valve 87 stops (off-state), the supply mouth side closure and exhaust side of solenoid valve 87 are beaten Open, and make compressed air flowing as the arrow of dotted line in Figure 10 represents, compression is discharged from operating room 76 to exhaust outlet 85 Air.

Using Figure 11 to it is in deceleration processing procedure, to operating room 76 supply compressed air pressure time change into Row explanation.Setting for the opening and closing opportunity of a variety of switching solenoid valves at regular intervals 87 is stored with ROM of unit control unit 15 etc. Fixed number evidence.As an example, (a) of Figure 11 is shown in certain period A alternately on-state and disconnections twice repeatedly State, turn-on time (ETAD expected time of arrival and departure of the invention) are shorter than the setting data drawing list of turn-off time (of the invention closes the time) Figure.In the same manner, (b) of Figure 11 is the figure that will turn on the setting data drawing list that the time is longer than turn-off time.Reading in Figure 11's (b) in the case of such setting data, since turn-on time is longer compared with (a) of Figure 11, on above-mentioned pressure is easy Rise.Wherein, period A is, for example, the short time of 0.1 second etc..Certainly, setting data are not limited to above-mentioned data.For example, Turn-on time can also be equal with turn-off time.The turn-on time of first time can not also be same with secondary turn-on time.Instead Multiple number may not be twice.

Unit control unit 15 is in moderating process of the package 100 with traversing roller 52, both circular velocities of calculating are poor at any time, Circular velocity based on the moment is poor, the optimal number in the setting data on the opportunity for reading in the on/off of switching solenoid valve 87 According to.For example, as shown in (c) of Figure 11, three kinds of respectively different setting numbers of the ratio of turn-on time and turn-off time are read in successively According to.If above-mentioned setting data are sequentially input supply control part 88 from unit control unit 15,88 one side of supply control part is based on Above-mentioned setting data make turn-on time change with turn-off time, and the opening and closing of solenoid valve 87 is alternately repeated on one side.It is used as it As a result, as shown in (d) of Figure 11, above-mentioned pressure carries out time change with the pressure of below pressure Pmax.Therefore, though not being to use Careful pressure adjustment as the situation in the variable portion 71 of air pressure, but, Neng Gou different from the control of conventional pump lock The feedback based on above-mentioned circular velocity difference is carried out in the moderating process of package 100, so that above-mentioned pressure is adjusted to arbitrary at any time Size.Therefore, it is possible to change the brake force for acting on package 100 at any time.

(2) composition of brake apparatus can also be added.In fig. 12, brake apparatus 92 also have be configured at air pressure can Above-mentioned solenoid valve 87 and supply control part 88 between the solenoid valve 81 in change portion 71 and operating room 76.As based on air The flowing of the compressed air of pressure variable unit 71, identically with above-mentioned Fig. 5, the arrow of solid line represent supply, the arrow of dotted line Represent exhaust.As the flowing of the compressed air of the opening and closing based on solenoid valve 87, the arrow of blacking represents supply, dotted line describe and The arrow of hatching represents exhaust.

Using Figure 13 to it is in deceleration processing procedure, to operating room 76 supply compressed air pressure time change into Row explanation.(a) of Figure 13 is pressure (solenoid valve 81 and the solenoid valve for representing the compressed air from the variable supply of portion 71 of air pressure The pressure of compressed air between 87) time change figure.(b) of Figure 13 is by the switching of the on/off of solenoid valve 87 The attached drawing of the setting data drawing list on opportunity.The ratio and its change and (c) of above-mentioned Figure 11 of turn-on time and turn-off time Shown situation is identical.In other words, though in the variation, it is 100 poor with the circular velocity of traversing roller 52 also based on package, Feed back the turn-on time and turn-off time of solenoid valve 87.If sequentially input above-mentioned set from unit control unit 15 to supply control part 88 Fixed number evidence, then 88 one side of supply control part, which is based on above-mentioned setting data, makes turn-on time change with turn-off time, on one side alternately The opening and closing of solenoid valve 87 is repeated.

(c) of Figure 13 is the time change of the pressure of compressed air for representing to supply to operating room 76 by solenoid valve 87 As a result chart.Double dot dash line represents the pressure for the compressed air that the variable portion 71 of the slave air pressure of (a) of Figure 13 supplies.Pass through The opening and closing of solenoid valve 87 is alternately repeated, so that the pressure of the compressed air in operating room 76 is got lower than from air pressure The pressure for the compressed air that variable portion 71 supplies.Further, since the turn-on time of solenoid valve 87 changes with turn-off time, therefore energy Enough adjust the pressure of the compressed air supplied from the variable portion 71 of air pressure to operating room 76.Therefore, it is possible to more meticulously change Act on the brake force of package 100.

In the variation, the ratio of the turn-on time of solenoid valve 87 and turn-off time can also be in deceleration processing procedures It is constant.In addition, solenoid valve 87 can also be the bidirectional electromagnetic valve that confession of the switching pressurized air to operating room 76 gives cut-out.

(3) composition of another brake apparatus can also be used.In fig. 14, brake apparatus 93 replaces the braking shown in Figure 12 The variable portion 71 of air pressure of device 92, and there is air pressure switch unit 94.Air pressure switch unit 94 with it is above-mentioned Supply mouth 84 connects.In addition, air pressure switch unit 94 is also connected with supply mouth 95, the supply mouth 95 and pressure ratio and supply The supply source connection of the low compressed air of the pressure of the supply source of the compressed airs of mouthfuls 84 connections.94 structure of air pressure switch unit As the compression for the compressed air and the comparison low pressure from supply mouth 95 for allowing hand over the ratio higher pressure for automatically supplying mouth 84 in the future In air any one whether to 87 side of solenoid valve supply composition.Air pressure switch unit 94 is controlled by unit control unit 15 System.In fig. 14, in the case where being supplied to the compressed air from supply mouth 84, compressed air as shown in the arrow of solid line that Sample flows.In addition, in the case where being supplied to the compressed air from supply mouth 95, compressed air strictly according to the facts paint and draw shade by line drawing Flowed like that shown in the arrow of line.

In above-mentioned composition, by weak Braking in volume making the package 100 small and light such as coil diameter slow down In the case of filling 100, unit control unit 15 is controlled air pressure switch unit 94, and is compressed with being supplied from supply mouth 95 The mode of air switches over.Also, as described above, supply control part 88 is controlled solenoid valve 87, alternately repeatedly into The on/off of row solenoid valve 87.Thus, though not being to have used careful pressure as the situation in the variable portion 71 of air pressure Adjustment, but compared with the variation of above-mentioned (1) only used the situation of solenoid valve 87 like that, can meticulously adjust above-mentioned pressure Power.In addition, the number of supply mouth is not limited to two, if increasing its number, finer pressure adjustment can be carried out.

(4) in brake apparatus 91~93, can also only make solenoid valve 87 turn-on time and turn-off time either one Change.

(5) brake apparatus 53,91,92,93 can not also have pressure gauge 86.For example, it is also possible to it will represent to indicate pressure Pre-saved with the chart of the relation on the opening and closing opportunity of each solenoid valve in ROM of unit control unit 15 etc..Alternatively, can also be by root The program for counting stating the opportunity of opening and closing according to indicator gage is pre-programmed into unit control unit 15.

(6) outside that can also be from the grade of control device 4 in addition to unit control unit 15 is inputted to air-pressure controlling portion 83 Indicate pressure.Alternatively, instruction pressure can also be inputted by operating personnel.

(7) can also be that the variable portion 71 of air pressure does not have air-pressure controlling portion 83, unit control unit 15 is as empty Atmospheric pressure control unit is controlled the variable portion of air pressure 71.Can also be that brake apparatus 91~93 does not have supply control part 88, unit control unit 15 is controlled solenoid valve 87 as supply control part.

(8) in deceleration processing procedure, unit control unit 15 can also converge on the side in defined scope with slippage The control of formula and brake apparatus 53 is in the lump controlled cylinder drive motor 62 and carries out the micro- of the circular velocity of traversing roller 52 Adjust.

(9) forming portion 12, which is wrapped, can also have the lift cylinder (not shown) for rotating reel cage 51.That is, can also be configured to It in the case where needing to make package 100 with 52 emergency stop of traversing roller, can rotate reel cage 51, and package 100 is rolled from traversing 52 separated compositions of cylinder.

(10) it can also be provided with and the angle of rotation of reel cage arm 51a, 51b are detected and to list in axis 54 of reel cage 51 etc. The rotation angle sensor (not shown) that first control unit 15 exports.That is, since reel cage arm 51a, 51b and roll diameter are correspondingly rotated And the change of the testing result of rotation angle sensor is produced, because this element control unit 15 can also be based on rotation angle sensor and volume The testing result of rotation speed sensor 61 is filled, calculates circular velocity, the amount of thread of package 100.

(11) winder unit can not also possess yarn accumulation portion 13.In fig. 15 it is shown that do not possess yarn accumulation portion 13 winder unit 10.The winder unit 10 possesses with to package as the composition for guiding yarns Y to yarn splicing device 33 The upper yarns Y 2 of 12 side of forming portion attract the upper yarn of the suction nozzle of seizure to catch guide member 96, with having to yarn feeder 11 The yarn under working Y1 of side attract the yarn under working of the suction port of seizure to catch guide member 97 etc..When connecing yarn, yarn under working Y1 with Upper yarns Y 2 catches guide member 96 by upper yarn respectively and is guided with yarn under working seizure guide member 97 to yarn splicing device 33.

In winder unit 10 when connecing yarn, unit control unit 15 to the lift cylinder that is described in the variation of above-mentioned (9) into Row controls and rotates reel cage 51, makes package 100 package 100 is distinguished with traversing roller 52 after the separation of traversing roller 52 Stop.In this way, in winder unit 10, when connecing yarn, without the deceleration that 100 are wrapped as the above embodiment.However, Such as at the time of being wrapped 100 and become completely volume, it is understood that there may be maintain the state of positive winding yarn Y while making package 100 Situation about slowing down with traversing roller 52.In the above cases, due to being free to braking of the corrective action in package 100 Power, therefore slippage can be reduced.Therefore, it is possible to prevent the unfavorable condition of skips, broken yarn etc..

(11) it can also rotate package 100 by the composition beyond traversing roller 52.For example, it is also possible to make without horizontal stroke The contact roller rotation of dynamic groove, so that 100 driven rotations of package, by making yarn from the traversing guiding piece of contact roller independence Y traversings.
