Definitions
- the invention relates to an apron for double apron drafting systems for spinning machines with a fiber bundling zone, which are the output roller pair of the main drafting zone connects and the delivery roller pair follows according to the Preamble of claim 1.
- a perforated strap for A drafting arrangement of this type is described in DE 43 23 472.
- the between the pair of output rollers and the pair of delivery rollers arranged pneumatic compression device has perforated straps that are in the middle of the running direction has arranged openings through which the suction air flow passes through to act on the fiber structure.
- the size of the openings can be dependent on the spun Thread number can be selected so that with a coarse thread number a coarser perforation than with a finer thread number is provided.
- the object of the present invention is the described Avoid disadvantages and create a strap that despite low suction power of the compression device Compaction effect of the known device improved.
- the object is characterized by the features of Claim 1 solved.
- DE 1.039.422 shows an apron with one in the transverse direction Perforated perforation.
- the device is not a strap for a compression device following a double apron drafting system, but a fiber separation, whereby after the The fibers are separated according to the perforation a finer or coarser fuse should be generated. It is a completely different spinning process.
- a double apron drafting system for spinning machines with one Fiber bundling zone which is the output roller pair of Main warping field and the delivery roller pair 5 follows, is in its entirety already in DE 43 23 472 described, so that only the invention Improvements to this drafting system are explained.
- FIG. 1 shows the apron 6 of the pneumatic compression device, which perforation breakthroughs 61, in the following Called compression holes 61, through a groove 62 are connected to each other.
- the groove 62 is strong drawn enlarged. Its width is based on the mass matched the fibers, which are summarized by the compression holes 61 become.
- the combined fibers lay in the groove 62, which is dimensioned so that it has a certain Clamping effect on the fibers. This will make the bundled Fibers up to the clamping line of the delivery cylinder 5 mechanically held so that the suction air flow only on bundling immediately after leaving the pair of exit rollers the drafting system needs to be turned off.
- a single groove 62 would be closed wide and would not have a clamping effect, on the other hand would be too narrow a groove 62 will not be able to make the mass of coarser To catch yarn.
- the fiber mass With several grooves 62, for example three, for fine yarns, the fiber mass only lies in the middle groove. The outer grooves remain free. But with that always achieved sufficient clamping.
- the grooves 62 are also arranged symmetrically to the region of the compression holes 61.
- FIGs 3 and 4 straps 60, 600 are shown, in which in addition to the compression holes 61 perforations 63 are shown, according to the invention their expansion transverse to the fiber transport direction is larger than in the fiber transport direction.
- Cross holes 63 is the compression device in capable of coarse compaction with particularly wide fiber dressings to effect.
- the fibers are still bundled even when they are traversed the position of the fiber structure changes.
- the transverse extent this cross holes 63 therefore suitably corresponds about the traversing stroke or the changed position of the Fiber dressing opposite the straps 6.
- Cross holes 63 and Compression holes 61 are arranged in alternation.
- the strap 60 in Fig. 3 is between two compression holes a transverse hole arranged. Cheaper for that However, air consumption is when the number of cross holes 63 is less than the number of compression holes 61. For example 4 is in each case in the strap 600 Transverse hole 63 arranged following two compression holes 61. This way, with low air consumption and traversing of the fiber structure achieved good compaction.
- Fig. 6 shows an embodiment in which the groove 41 in the strappy cage 4 are only less than half the length of strappy cage 4 extends.
- the to the suction line 42nd connected groove 41 lies in the delivery cylinder 5 facing away Part of the strappy cage 4 and is to the output cylinder of the drafting system open.
- the length of this suction zone is about 10 to 25 mm. In this short area is the fiber structure already fully summarized.
- the suction zone can therefore be as short as possible to save suction air performance be held, i.e. it is only as long as it is for the summary of the fibers is absolutely necessary.
- the distance between the cylinder clamping lines is corresponding the stack length larger. Even then, the suction zone does not have to be larger his. Following the suction zone, gffs then take over. the grooves 62 in the straps 6 the cohesion or the clamping the combined fibers as already described above.
- Additional densification can also take place between the suction zone defined by the groove 41 and the clamping line of the delivery cylinder 5.
- a channel 43 is provided for this purpose, which the groove 41 with the post-compression area before Delivery cylinder 5 connects.
- 11 and 12 is an alternative embodiment of the compression device shown at which two perforations 61 and 61 'and 63 and 63' are provided.
- the perforation 61 ', 63' also include the perforation holes Grooves 62 connected.
- 3 and 4 are here summarized, however, is due to the asymmetrical arrangement the groove 410 in the strappy cage 40 always only one of the rows of perforations in operation.
- the groove 410 is via a suction line 420 connected to the suction, not shown.
- This version has the advantage that by reversing the Strappy 660 the compacting device in a simple manner adapted to different sliver strengths and material requirements can be.
- the strap 660 can thus be used more flexibly as a strap with only one row of perforations.
- a free space in the spout of the delivery cylinder 5 is created in that immediately after a web 2 is arranged on the clamping line of the delivery cylinder 5 is over which the strap 6 is guided.
- Web 2 is on attached to a holder 21. By adjusting this holder 21 the web 2 is adjustable. Through this web 2 is not only a space is created to prevent the fibers from becoming trapped, but through the sharper deflection of the straps 6 the fibers also loosen, especially with fine yarns, better off strappy 6. Peeling fibers is on everyone Case avoided, resulting in a better and more even Yarn quality leads.
- FIGS. 9 and 10 show an embodiment in which a cleaning device for the compression device is provided.
- a blown air line 45 with a connecting piece 44 opens into the groove 41 opposite in the strappy cage 4 the mouth of the suction air line 42. Should cleaning take place, so this compressed air line 45 compressed air initiated, but at the same time the negative pressure via the suction line 42 maintained. It has been shown that the Impurities that are mostly in the groove 41 and especially start at the mouth of the suction line 42, on this Way can be successfully eliminated.
- the compressed air is fed to the connecting piece 44. This can be done by hand, however also done by a walking machine.
- the suction effect can also be reduced if that the perforation is clogged by dust deposits. Also can cause ridges on the edges of the perforation to become Hang the fibers on it.
- burr-free perforation is problem-free works even with very dirty material without clogging.
- Such a burr-free perforation is caused by breaking the edges conveniently achieved by the usual punching process usually have a burr.
