Abstract
In a previously known device, the voluminous fleece that is conveyed on an endless belt for water needling is compacted between a needling drum and the belt while being wetted by a first water curtain from a nozzle beam, the water jets of which initially penetrate the endless belt, then the fiber web, and finally the needling drum. A second endless belt which is associated with the first one is disposed thereabove, the two endless belts being conically directed towards each other in the operating zone, thereby pre-compacting the fiber web that is to be delivered to the needling drum. The two endless belts are pressed against the needling drum along with the fiber web that is disposed therebetween by means of two rolls and are simultaneously wetted with the aid of water jets of a nozzle beam which is arranged between the tightly associated rolls. The wetting point is not located in the compacting zone of the two superimposed endless belts but downstream of the compacting zone in the direction of conveyance of the fiber web in order to rinse one endless belt from the fibers that adhere thereto while the fiber web is redirected onto the needling drum without longitudinal tractive power being applied.

Background technology
European Union's patent is the device of EP-A-0 859076, it has an advantage: can send the fluffy fibrous material of preparing the water thorn by tape loop and compress between acupuncture cylinder and tape loop, the first road cascade with spray boom soaks it simultaneously, and the current that this spray boom ejects will flow through tape loop, fibre bundle, acupuncture cylinder successively.This device also has an advantage, and fluffy exactly proal fibre bundle by compressing at leisure from the onesize pressure of upper and lower both direction, therefore fragmentation and jump can not occur between two tape loops.Subsequently, when it during between two tape loops and by a longer extruded segment tensioning, will be soaked.
In addition, mention among the FR-A-2 821 866, be used for the removable setting of roller of the outlet side of first tape loop, be used for tape loop is compressed in the acupuncture cylinder with more strengthening.Therefore, the tape loop (corresponding being compressed on the acupuncture cylinder) that at first is tangential on the acupuncture drum driven contacts with the acupuncture cylinder with a bigger cornerite littlelyr.In order to change the cornerite of tape loop and acupuncture cylinder, layout to spray boom is considered, promptly in known devices, making spray boom center on the acupuncture cylinder is provided with rotationally, thereby impact on fibre bundle and the acupuncture cylinder with a line from the cascade that the nozzle of water beam comes out, this line is between the mid point and terminal point of constricted zone.
The fine task of having finished of this device: will slowly compress by fibrous fibre bundle loose, that no binder is reinforced, and make it under pressure state, to be soaked.Because fibre bundle obtains compression and soaks under loose condition (of surface), loosened again subsequently and prepared further acupuncture, so the fibre bundle after soaking is certain to stay individual fibers on the tape loop that compresses.These fibers can pollute tape loop, and hinder the continuation optimization process of back fibre bundle.Although can give the tape loop of idle running additional a kind of cleaning device, price may be quite expensive, can raise the cost.
Summary of the invention
Therefore, the objective of the invention is to create a kind of device, both can make tape loop in operating process, clean out fiber voluntarily, help fibre bundle again and break away from tape loop.
H) the present invention is provided with spray boom and in alignment with between the roller that drives a tape loop, promptly the water flow jet of this spray boom only just impacts fibre bundle after compressing surface on the direction of transfer of fibre bundle in this way; Be that the truncation Line of water flow jet is positioned at two tape loops driving each other via two rollers then again by lead the respectively place of detaching direction of two other rollers.
This arrangement of spray boom in the device framework arrangement of the injection stream ejection position of from spray boom, coming out beyond constricted zone in other words, both can carry out constant soaking, fibre bundle is come by the tape loop disengaging of jet water course and extruding the fibre bundle under suppressing.The current that soak are pressed in fibre bundle and continue on the running acupuncture cylinder, and washing out simultaneously may be attached to the fiber on the tape loop, and these fiber bands is got back to fibre bundle get on.
When fibre bundle is propped up moulding by two tape loops, should do not soaked; Only these two tape loops from top and below mutual motion be about to just should be soaked in blink separately.Do not go wrong in guaranteeing to soak, should have only several centimetres poor between the defiber of two tape loops and the engagement point of jet water course, be approximately 20-50mm.
Description of drawings
Fig. 1 is the compression needling device at a side view in the large equipment more.Herein, the slewing rollers of first tape loop are to soak roller, also play a part the acupuncture cylinder simultaneously again.Have the top that second tape loop that soaks spray boom is positioned at it.
Fig. 2 is the local amplification view that soaks roller and acupuncture drum segment among Fig. 1.
Fig. 3 is the impact of jet water course among Fig. 2 and the local amplification view that soaks the position.
The specific embodiment
Compression waterpower needling device in the framework 1 only is denoted as " acupuncture cylinder 2 ", and this mainly is to be convenient to the Fig. 1 that explains according to EP-A-0 859 076.Like this, a bigger water thorn device can be described uniformly.It has more acupuncture cylinder, and these acupuncture cylinders are the reversion shape round a loose fibres bundle, and it is carried out double treatment.
This device generally is made up of a tape loop 3, and this tape loop is by a plurality of rotatable roller 2,5 rotation tensionings in the support frame 4.Direction by arrow 6 on this tape loop is transmitting the fluffy fibre bundle 7 that is about to acupuncture.At first, this fibre bundle may be unfixed, and directly is placed on the tape loop 3 by a carding machine that does not indicate.If carry out in such a way, roller 2 just plays a part the acupuncture cylinder.In other words, its diameter is bigger and be used as the permeability roller, and it is positioned at next door, hydraulic blow position and air exhausting device (arrow 8) below at least.
Two rollers of second tape loop 9, promptly roller 11 and roller 12 ', directly contact with the acupuncture cylinder 2 of first tape loop 3.In other words, pressing the tape loop 3 that transmits fibre bundle 7, moving towards the direction of acupuncture cylinder together by the tape loop 9 of roller 11 and roller 12 ' tensioning and drive.They fit tightly each other, only stay a little space, can shift spray boom 14 onto tape loop 9 and get on.By the not only slowly compression between tape loop 3 and tape loop 9 by this way of fibre bundle 7 of the reversion section 3 ' transmission of tape loop 3, and, be crushed on the acupuncture cylinder 2 on the x scope through the part y between two tape loops 3 and 9.Fibre bundle 7 is soaked by spray boom 14 under this pressure state, can carry out acupuncture subsequently.
Shown in the embodiment of Fig. 1 acupuncture cylinder 2, when tape loop 9 by roller 12 ' when upwards drawing, separate with tape loop 9 top of fibre bundle 7.Like this, acupuncture cylinder 2 just is axially parallel with two acupuncture spray booms 15,16 in the roller workflow, and these two spray booms twine first to fiber.Fibre bundle continues to be sent to next executive component 17 by tape loop 3, and is recycled thereupon and is with 3 to unclamp.
In like manner, according to Fig. 3 embodiment of EP-A-0 859 076, acupuncture cylinder 2 is slewing rollers of second tape loop 9, and fibre bundle 7 is sent by first tape loop 3, upwards soaks then.
