Also known (DE102005056534A1) uses a kind of upper leather ring to substitute the guiding apron with woven lining, and this upper leather ring comprises a webbing of being made by polyamide filaments.This guiding apron has good sliding properties with respect to metal or analog.
Summary of the invention
Task of the present invention is, a kind of guiding apron that starts described type is provided, and it is right that it can be directed into the roller subsequently of as far as possible closely pressing close to drafter.
This task is to solve like this, that is, the guiding apron is formed by a kind of fabric, and its warp thread and weft yarn have the rugosity and its outside that are not more than 0.2mm respectively and be provided with the layer of being made by the material of caoutchouc elasticity, and this layer has the thickness that is not more than 0.3mm.
Only this guiding apron that is provided with rubber elastic layer on its outside easily slides on the steering component of being made by metal or analog by its inboard, thereby can use the steering component with less relatively turning radius.Even, therefore can guide the guiding apron up to closely clinging on the right jaw line of next roller because the guiding apron has advantages of small integral thickness and also has good sliding properties around the less steering component of turning radius.Reach the right jaw line of roller of following and just fiber can be pulled out from fibrous material in case adopt the coating of material of the caoutchouc elasticity of single face to cause forming a kind of flat to a great extent outer surface and assurance fiber, the while fiber is not exceedingly clamped.
Stipulate that in another embodiment of the present invention the spacing between the warp thread and between the weft yarn is respectively approx corresponding to the rugosity of warp thread and the rugosity of weft yarn.Even guarantee that thus this material also can not see through fabric but remain essentially on the side that applies this material when the material of caoutchouc elasticity applies with the form of liquid state.
A kind of double belt drafting mechanism is set in an embodiment of the present invention, and wherein upper leather ring is according to guiding apron of the present invention at least.In another embodiment the regulation, dispose a director element between a reversion Duan Zaiyi steering component of upper leather ring and a top roller, it with this reversion section towards draw zone in-plane upper deflecting.Because therefore the outside phase configuration of the material with caoutchouc elasticity of this director element and guiding apron stipulates in another embodiment of the present invention that director element has columniform structure and kept rotationally.This director element has only increased the running resistance of upper leather ring on not half.
From following description, draw other advantage of the present invention and feature to the embodiment shown in the accompanying drawing.
Description of drawings
Fig. 1 has shown the sectional view by the main drawing area of a duo roth system;
Fig. 2 has shown a detail view along the direction of the arrow II of Fig. 1.
The specific embodiment
Figure 1 illustrates two rollers to 1,2 and 3,4, between them, form one and be used for wanting the ribbon of drawing-off or the draw zone of rove 5.Bottom roll 2 and 4 is configured to the fluted roll that driven continuously on vertically at machine usually, and top roller 1,3 belongs to so-called and twoly compresses roller, that is each two top roller 1 of adjacent drafter and two top rollers 3 are bearing on the public axle.Roller 3,4 for the drawing-off of hope with a rotational speed higher than roller 1,2, thereby ribbon 5 is opened by drawing-off mutually for the drawing-off of hope in draw zone and thus by drawing-down, the quantity of the fiber on promptly every cross section reduces
Fiber is imported in the draw zone of the double belt drafting mechanism with upper leather ring 6 and following apron 7.Upper leather ring 6 twine top rollers 1 and steering component 8 and down apron 7 twine bottom roll 2 and steering components 9.Upper leather ring 6 and following apron 7 abut in together in draw zone mutually.
The steering component 8,9 of upper leather ring 6 and especially steering component 8 be directed up to closely near subsequently roller to 3,4 jaw line.Thereby roller to 3,4 and the apron guiding mechanism between, the drift passed through by fiber is quite little.The steering component 8 of upper leather ring 6 has a little turning radius, and its order of magnitude only is 2.0mm, therefore can with and the jaw line between spacing keep very for a short time.In addition, on the direction on the steering component 8 and the reversion section between the top roller 1 of upper leather ring 6 is deflected draw zone by means of director element 10 plane.Steering component 8 keeps by means of retainer 11, and retainer is maintained in the supporting and loading arm that top roller 1,3 is supported in the mode that is not shown specifically.Retainer 11 is flexible member and form bearing from the upper leather ring side advantageously, releasably keeps director element 10 in bearing.
In a kind of embodiment of modification, the columniform director element of a rotatably support is set, it replaces the director element 10 with flat strip.
Used the guiding apron that is formed by thin webbing as upper leather ring 6 and following apron 7, they are on its outside, and the outside that promptly holds ribbon between it is provided with a layer of being made by the material of caoutchouc elasticity.This fabric is made of warp thread and weft yarn, and it has the rugosity that is not more than 0.2mm respectively, thereby fabric has the thickness that is 0.4mm to the maximum.The layer of being made by the material of caoutchouc elasticity is arranged in the thickness that is not more than 0.3mm, thereby the guiding apron has the gross thickness that is not more than 0.7mm.This guiding apron flexible very good, thus can be used as upper leather ring 6 or down apron 7 around having the steering component setting and the guiding of very little turning radius.Because the inner surface that reclines with steering component 8,9 of upper leather ring and following apron is made of fabric, especially the fabric made of the mono filament that is made of polyamide constitutes the therefore only very little sliding friction of formation on these steering positions.The mutual opposite external side of upper leather ring 6 and following apron 7 has relative more smooth surface in draw zone, thereby fiber is in case caught 3,4 by roller and just can be drawn out and can not break.
The following apron that is bearing on the bottom roll that has groove by its inboard that is formed by fabric is pressed in the groove by top roller 1, thereby it is driven and transmission reliably.
The outside with them on upper leather ring 6 and the jaw line of following apron 7 between roller is to 1,2 abuts in together mutually., this outside is formed by the material of caoutchouc elasticity.Make the profile of corresponding fabric generally be pressed in the layer of this caoutchouc elasticity by higher relatively chucking power, thereby guarantee being synchronized with the movement reliably between upper leather ring 6 and the following apron 7.
A kind of material coating of caoutchouc elasticity of liquid state is advantageously weaved and used then to the guiding apron on circular loom, it follows quilt cure process at least in part.Make a kind of close fabric, because only keep a kind of spacing that is not more than its rugosity between the warp thread and between the weft yarn.The material that guarantees the caoutchouc elasticity apply thus can not pass fabric, thereby makes the inboard not have the material of caoutchouc elasticity.Then cut into single guiding apron by tubular material.
