Referring now to embodiment shown in the drawings the present invention is described in more detail, wherein:
Fig. 1 schematically shows converging device at the side view perpendicular to the fibr tissue throughput direction;
The longitudinal section of whole converging device in the mesh screen zone in Fig. 2 presentation graphs 1;
Fig. 3 represents along the top view of Fig. 1 arrow 26 directions;

The specific embodiment
According to Fig. 1, fibr tissue 10 utilizes the pulling equipment (not shown), discharges from the roller gap between feeding roller 24 and the focal element 262, thereby makes feeding roller 24 and focal element 262 can become the outlet roller of pulling equipment.In the distance of roller clearance measurement, be provided with one at the periphery of focal element 262 and converging roller 262 tops and converging the mesh screen 30 that the roller distance is h, with regard to magnetic-attraction element 200, the side-play amount of these mesh screen 30 leading edges and fibr tissue throughput direction is b.As shown in Figure 1, clearance height h reduces downwards gradually at the throughput direction of fibr tissue, and the air that the result laterally promptly goes into the absorption in the gap between mesh screen 30 and the focal element 262 in the axial flow of roller 24 and 28 is concentrated gradually.
According to Fig. 1, clearance height h measures boost line and begins to descend gradually away from the position of focal element 262 from being positioned on the material flow path direction between the surface of mesh screen 30 and focal element, therefore causes the wedge shape development in gap between mesh screen 30 and the focal element 262.Clearance height h can circumferentially reduce according to linear function or a higher order functionality the whole of whole focal element.From near mesh screen 30 tops a bit, clearance height h can reduce according to another function at the circumferencial direction of focal element.Under the simplest situation, be positioned at the end of outlet roller 28 up to mesh screen 30, this clearance height all is a constant.In addition, Fig. 2 is to represent from mesh screen 30 edges near 30 thick line towards the central authorities that fibr tissue is set, gap between mesh screen 30 and the focal element 262 also is that clearance height h can reduce, and causes quickening gradually according to the hydrodynamics continuity law along the air flow that arrow flows on u.The clearance height h that (according to Fig. 2) all reduces gradually on the throughput direction of the fibr tissue 10 that is positioned at focal element 262 (Fig. 1) periphery and the direction vertical with throughput direction that is lower than mesh screen 30 thick lines at longitudinal section causes convergence effect because the air flow that quickens and further improving continuously.
Fig. 2 represents the profilograph of converging device 262, and it is under same magnetic-attraction element 200, on the fibr tissue 10a on mesh screen 30 and focal element 262 outer surfaces.Along arrow laterally flow into 30 and 262 air along the arrow under the hole 266 by the hole 266 in the convergence zone 200a of magnetic-attraction element 200.The edge of mesh screen 30 protrudes in and converges outside the zone 264, and its mesopore 266 horizontal left and right sides side-play amounts are u, therefore forms a pipeline that makes the air aligned fibers tissue that enters between mesh screen 30 and focal element 262.Fibr tissue 10 outstanding edge fibers are reached unanimity.A width m is extended in hole 266 in focal element 262, be k thereby make the width of suction inlet 200a.
As shown in Figure 3, two fibr tissue 10a, 10b can be conducted through focal element 262.The throughput direction of fibr tissue 10a or 10b tilts to the axle of focal element, and promptly angle is greater than 90 degree.Mesh screen 30 covers two fibr tissue 10a, 10b.A recess 30a must provided, so that in ambient atmosphere can as far as possible laterally flow into gap between mesh screen 30 and the focal element 262 downwards from described recess 30a between the fibr tissue of fibr tissue entrance side.Attract regional 200a to tilt along dotted line.And extend a length 1 towards the direction of fibr tissue 10a below.Magnetic-attraction element 200 is provided with one and attracts regional 200a, this zone 200a is positioned at the throughput direction of fibr tissue 10, and the clearance height between the focal element of mesh screen and placement fibr tissue, also promptly reduce from the mesh screen edge towards central authorities at material stream and/or perpendicular to the direction that material flows.This basis is measured perpendicular to the projection of the converging device 26 of the axle of focal element 262.
In Fig. 4 a, the width that extend in hole 266 is bigger than the width that attracts regional 200a, is u so that mesh screen 30 exceeds the edge that attracts regional 200a or exceeds the elongation that converges the zone.In this case, converging zone 264 is limited in the width that attracts regional 200a.According to Fig. 4 b, the effective width that converges zone 264 is different from the width in hole 266, even attract a bigger zone of width k extend through in zone.In this case, mesh screen 30 is laterally projecting is u in the overhang that converges on the zone 264.Overhang u can adopt 100 times of clearance height h.
The optimum value of the above-mentioned size of mentioning all is an absolute value, and relevant with accompanying drawing.The yarn quality value that adopts above-mentioned converging device acquisition is considerably beyond traditional annular spinning machine.
As shown in Figure 2, mesh screen 30 can be provided with a hole 30b, perhaps can be made by a kind of gas permeable material.Utilization makes fiber more effectively converge on focal element perpendicular to the air-flow of the scheduled volume on focal element surface.
