The axle 27A that feed rolls 27 is fitted thereon can be rotated by the 3rd motor 55.

Advantageously, in certain embodiments, the 4th motor 57 makes the roller 35 be assemblied on axle 35A rotate.

In like fashion, the rotative speed of feed rolls 23,27 and 35 and unwinding roller 22 can be controlled independently.

The take up roll 43A-43D driven by motor of four winding position 17A-17D on each foreground 3A, 3B of machine 1 can be advantageously motor operated by a pair, and each motor makes two operating axis of the take up roll of two adjacent windings positions rotate.In certain embodiments, the axle 61 and 63 that motor 59 makes take up roll 43A and 43B of winding position 17A and 17B be fitted thereon rotates.Advantageously, annular flexible parts can be arranged in certain embodiments be such as with, be preferably cog belt 65, the Movement transmit from public motor 59 to the axle 61 and 63 of two general parallel orientation, rotates in the mode of basic synchronization to make the series of take up roll 43A and 43B driven by motor by it.

The axle 69 and 71 that take up roll 43C and 43D that another motor 67 be positioned at below motor 59 can be set up to make to be driven by motor is fitted thereon respectively rotates.Annular flexible parts (such as cog belt 73) can by the Movement transmit from motor 67 to two axles 69 and 71.Obtain the synchronous rotary of take up roll 43C and 43D driven by motor of winding position 17C and 17D in like fashion.

In an advantageous embodiment, another motor 75 makes the axle 77 of the traverse gear 45A of control first winding position 17A rotate and second operating axis 79 of the traverse gear 45B of the second winding position 17B is rotated.Flexible part (such as cog belt 81) by the Movement transmit from motor 75 to the axle drive shaft 77,79 of traverse gear 45A, 45B.So these traverse gears are synchronously controlled by public motor 75.

In fact, in the embodiment that this is favourable, winding position 17A-17D is divided into two groups, and these two groups comprise winding position 17A, 17B and winding position 17C, 17D respectively.The winding position of every a pair alignment comprises relative to another motor to the motor independent operation of the winding position of alignment.Motor 59,75 controls the moving-member (take up roll and traverse gear) of winding position 17A, 17B, and motor 67 and 83 operates the moving-member (take up roll and traverse gear) of winding position 17C, 17D.

Can control motor 59,75 independently relative to motor 67,83, thus the fact can with the length differed widely is considered to some extent.Even if the length in feeding path is different, by acting on motor 59,75 independently and motor 67,83 can compensate the change of the feeding condition of yarn FC thus obtain substantially mutually the same reel B3.In fact, relative to the rotative speed of rotative speed amendment take up roll 43C, 43D of take up roll 43A, 43B, and the reciprocating speed of traverse gear 45C, 45D can also can be revised relative to the corresponding speed of traverse gear 45A, 45B.The change of speed can compensate the different feeding tension force along generating from the holding part between roller 35,37 to the path of the variable-length of the yarn FC of the winding point on corresponding reel B3.

Separate motors actuating device is used for two also to allow to realize additional advantage to stacked take-up unit.Especially, the machine configured thus allows two strands of yarns along two parallel path ground feedings and processing be separated and they is collected on single final reel B3.So, in each the section comprising four take-up unit and four thread paths, all four paths but only two take-up unit will be used to form two reels concurrently, on each reel reel two strands of yarns.When machine operates in like fashion, one in two motor drives and all parts of controlling thus can keep stopping.

According to favourable embodiment, in order to obtain the compacter layout of the reel B2 of elastomeric yarn F2, in the configuration of the strut member 20 of these reels B2, adopt specific means.In fact, advantageously all reel B2 of elastomeric yarn F2 are arranged in identical height to prevent the difference of the feeding condition of the various elastomeric yarn F2 arriving interlacing nozzle 31.For this reason, strut member 20 must be arranged so that corresponding to collect reel B3 axial dimension occupied area in arrange four reel B2 of elastomeric yarn.In like fashion, the reel of elastomeric yarn F2 can be placed substantially coaxially with each other and every one therefore collected in four gangs of elastomeric yarn F2 of position for four that are fed into below can limit substantially identical path, and this is favourable to the conformability of the working condition of the various reel B3 of complex yarn FC.

For the ease of handling the reel B2 of elastomeric yarn in the step changing the reel exhausted with new reel, and such as also need to recover feeding when the accident fracture of elastomeric yarn, in some embodiments provide the particular form of the strut member 20 in Fig. 3.Additional structure and the function detail of the embodiment of strut member 20 will be described particularly now with reference to figure 6A-6C, Fig. 6 A-6C axonometric drawing and show the part that strut member 20 is arranged in region wherein at different operating positions.

In certain embodiments, each strut member 20 comprises the arm 91 of the fixed sturcture 93 being limited to machine 1.Advantageously, each arm 91 can be pivoted to structure 93 and can be set to have according to the limited pivotal movement of double-head arrow f91 around fulcrum 91A in 91A.

Fig. 6 A and 6B shows the arm 91 being in two different Angle Position by example.In fig. 6, arm 91 is placed on an Angle Position and sentences the outside face of the corresponding reel B2 of elastomeric yarn F2 is contacted with the cylindrical outer surface of unwinding roller 22.In this case, being rotated through of unwinding roller 22 is rubbed and causes the rotation on the unwinding direction of reel B2.It is to be understood that when reel B2 contacts with unwinding roller 22, the position residing for arm 91 changes according to the diameter of reel B2.When the diameter of this reel reduces due to the consumption of elastomeric yarn F2, arm 91 rotates because of gravity, and namely downward pivotable, keeps the contact between the outside face of reel B2 and the outside face of unwinding roller 22.

Fig. 6 B shows the maximum lift position of the arm 91 of the strut member 20 of the reel B2 of elastomeric yarn F2.In this position, the core of the corresponding reel B2 of elastomeric yarn F2 or flange A2 are positioned to the corresponding drg 95 against being carried by the respective brackets 97 be locked on the fixed sturcture 93 of machine, and bracket 97 is preferably in and can carries out by means of such as screw 99 and slit 100 Angle Position that regulates.The adjustment of the Angle Position of bracket 97 allows to make the position of drg 95 be suitable for the size of the flange of the reel B2 of elastomeric yarn F2 or the diameter of core A2.
