The shape of the suction seam 57 of hookup mechanism is not limited to the shape of the 4th embodiment shown in Figure 11.Such as, the lateral edges 61 of suction seam 57 can unnecessaryly be straight, and it can comprise two different straight sides edge, be namely parallel to the downstream part 60B of guide edge 60 and cross downstream edge portion that imaginary line L1 extends and the upstream portion that parallel lines imaginary line L1 extends.The downstream edge portion of lateral edges 61 can relative to imaginary line L1 with the less angular slope of the downstream part 60B than guide edge 60, and the upstream portion of lateral edges 61 can be crossed imaginary line L1 and tilt less relative to imaginary line L1 than the upstream portion of guide edge 60.
As illustrated in fig. 12, but suction seam 57 can have not to be straight to comprise the lateral edges 61 of two straight sides edge, namely along the upstream portion 61A that and the downstream part 61B that extends of the basic equidirectional of downstream part 60B of the guide edge 60 and direction contrary with the upstream portion 60A of guide edge 60 relative to imaginary line L1 edge extends.Both upstream portion 61A and downstream part 61B cross imaginary line L1, and the upstream extremity of downstream part 61B is positioned on the side of contiguous guide edge 60 of imaginary line L1.In addition, the upstream edge 57A of suction seam 57 crosses imaginary line L1, and the width W 1 of upstream edge 57A is greater than the situation that suction seam 57 has the upstream edge 57A not crossing imaginary line L1.
When switching the feeding of the rove in Weaving device (there is the suction seam of Figure 12 A in suction pipe 56), if the front end just entering the fibre bundle of suction seam 57 is arranged in the region of the upstream portion 61A corresponding to lateral edges 61, then the upstream portion 61A of the front end edge lateral edges 61 of fibre bundle moves.While upstream portion 61A movement, the front end of fibre bundle close to will with the cut-off rear end of the fibre bundle of its link.
Alternatively, if the front end just entering the fibre bundle of suction seam 57 is arranged in the region outside corresponding to the above-mentioned zone of the upstream portion 61A of lateral edges 61 or is arranged in substantially correspond to the upstream portion 60A of guide edge 60 and the region of downstream part 60B, then the upstream portion 60A of the front end edge guide edge 60 of fibre bundle moves.Near downstream 60DP along while the 60B movement of downstream part, the front end of fibre bundle close to will with the cut-off rear end of the fibre bundle of its link.
The suction seam with Figure 12 A of the lateral edges 61 comprising downstream part 61B and upstream portion 61A 57 can be modified as follows, and namely downstream part 61B and upstream portion 61A is formed by two different straight sides respectively.In each side of these two straight sides forming downstream part 61B and upstream portion 61A, one in the straight sides of upper and lower can be different from another the angular slope in the straight sides of upper and lower.
As shown in Figure 12 B, suction seam 57 can have Y shape shape substantially.In the suction seam 57 with such shape, form guide edge 60 by multiple side, and the upstream portion 61A of lateral edges 61 and downstream part 61B also can be formed by multiple straight sides.
The shape of suction seam 57 is not limited to the shape of above-described embodiment, but guide edge 60 can be formed by single straight edge, comprises the shape of Figure 12 B, as long as the width W 1 of upstream edge 57A is greater than the width W 2 of downstream edge 57B.
Suction seam 57 can be bend portions.Such as, guide edge 60 can be bending at least partially, lateral edges 61 can be bending at least partially, or suction the upstream edge 57A of seam 57 and a part of downstream edge 57B can be bending.
Suction seam 57 shown in Figure 11, Figure 12 A and Figure 12 B can be formed to overturn shape.Such as, when the suction seam 57 of Figure 11, the guide edge 60 on right side observed in the accompanying drawings and the lateral edges on left side 61 can overturn.
As shown in figure 13, the conveying roller forming a part for anti-roll twist device 23 can be used as lower roller 25A before drafting system 21 to the lower roller 47A of 47.The diameter that front lower roller 25A has is enough large to allow guiding elements 64 to be used as hookup mechanism 22 to be arranged on conveying roller to before 47 between apex roller 25B and apex roller 47B.Guiding elements 64 is so configured to be narrowed by the spacing distance between two rove S1, S2 of front lower roller 25A and the feeding of front apex roller 25B institute, as in a second embodiment guiding elements 54 when.Although conveying roller shares front lower roller 25A to 47 with drafting system 21, but apex roller 47B is not used as drawing roller.
In hookup mechanism 50, the conveyer transporting rove S1, S2 needs not to be belt conveyer 51, but can use the bottom apron of apron device.Under these circumstances, as compared with using the situation of belt conveyer 51, rove S1, S2 can be directed closer to anti-roll twist device 23, this is because annular apron is wrapped on driven roller and cradle.The apron of engagement can be used to bottom apron.
The apron of engagement can be used to conveyer, makes the conveyer when fibre bundle will be linked by using positive and negative air pressure can not interfere the fibre bundle of link.In addition, compared to the situation using virgin coil, conveyer can be lighter.
In hookup mechanism 50, the conveyer transporting rove S1, S2 need not have band 53, endless belt or apron, but can use single or multiple roller.
Conveyer can by conveying roller to 47 lower roller 47A, front apex roller 25B or apex roller 47B and driven by front lower roller 25A.In addition, conveyer can be provided with the driver of himself.
When withdrawing air is used to link described multiple rove while multiple rove is just transported to anti-roll twist device 23 from drafting system 21, air flue can be formed in the roller forming conveyer and band.
When hookup mechanism 50 has in the second embodiment guiding elements 54, belt conveyer 51 can be replaced by ultrasonic vibration plate.Under these circumstances, accept very little contact resistance towards first and second rove S1, S2 of anti-roll twist device 23 movement by preliminary roller to 25 feedings and on ultrasonic plate, make rove S1, S1 by preliminary roller to 25 thrust move to anti-roll twist device 23.
The guided plate 54A of guiding elements 54 can be formed by ultrasonic vibration plate.In this case, can easily be guided two of 25 feedings rove S1, S2 by preliminary roller so that movement is close each other.
Although special yarn Weaving device 10 is constructed such that with first and second rove S1, S2 from coarse yarn axle 13A, 13B as drawing-off and the fibre bundle being woven into yarns Y, but sliver also can be used as fibre bundle.
Fibre bundle source of supply 11 can comprise can by feeding independently more than the fibre bundle of two.Such as, can be so constructed to make three different fibre bundles (rove) by feeding independently, thus make yarn comprise continuously predetermined length with three of any order kinds of fibers, or with two kinds of fibre bundles of the continuous predetermined length of any order.
