Definitions
- the invention relates to a ring spinning machine with compression devices, each of which contains a compression strap having at least one perforation track, which runs over a suction shoe and which is opposed by a cover surface which is formed on an insert which is arranged on a support rail extending along the compression devices.
- Such compression devices serve to suck protruding fibers onto the fiber sliver and thereby reduce the hairiness of the yarn produced. This also increases the tensile strength of the yarn and improves its processability into woven or knitted fabrics.
- the cover area assigned to the compression area shields the compression area against disturbing air turbulence, for example of a traveling cleaner.
- fiber accumulations very easily build up on the edges of the insert having the cover surface, which accumulate uncontrollably and can lead to thick spots in the yarn. These thick spots reduce the quality of the yarn and can lead to thread breaks in its further processing.
- the object of the invention was accordingly to design the insert having the cover surface in such a way that the tendency to accumulate fibers is reduced. It solves this problem by the features mentioned in the characterizing part of the main claim.
- the fact that the insert is designed as a plastic injection molded part, it offers the possibility of avoiding burrs, which can arise, for example, by machining, and also often one tool-dividing line with sharp edges so that it faces away from the material flow. This avoids the accumulation of fibers on it, or if such should have nevertheless formed, when they detach them into the
- the insert piece can "ride" on the support rail in that it rests on the two side surfaces thereof with two legs.
- the insert piece can "ride" on the support rail in that it rests on the two side surfaces thereof with two legs.
- Insert piece and still offers the possibility to offset the front and rear webs, viewed in the direction of material travel, in the longitudinal direction of the support rail in such a way that the dividing line of the injection mold is not in the area of the material flow.
- a curvature of the web of the insert piece opposing the material flow in the direction against the material flow has the advantageous effect that material deposits that could have formed on this surface are pushed to the side and are not guided into the fiber run.
- the all-round gripping of the support rail by the insert also offers the advantageous possibility of providing a clamping screw in its lower plate, ie facing away from the material flow, by means of which the insert that can be displaced along the support rail can be fastened in a functional position.
- FIG. 1 shows the cross section through the area of a ring spinning machine drafting system equipped with the compression device;
- Fig. 2 shows the spatial view of an insert obliquely
- FIG. 1 shows the compacting device 1, which is arranged downstream of the pair of output rollers 2 of a common drafting system, of which only this pair of output rollers is shown. With 3 the run of the fiber material is designated.
- the compression device 1 is of a type known per se. It includes one
- Suction shoe 4 which is connected via a suction line 5 to a suction device, not shown here.
- the suction shoe 4 has a suction opening 6 on its underside, through which a compression strap 7 is guided. To the extent this compression strap runs a perforation track of small suction holes, which is guided over the suction opening 6.
- the compression apron 7 is moved over a pair of rollers 8, the lower roller 9 of which is driven over all drafting units of the ring spinning machine and the upper roller 10 of which is pressed spring-loaded onto the lower roller via an upper roller supporting and loading arm, not shown here.
- Suction shoe 4, top roller 10 and compression straps 7 are guided in a cage 11, which is also held on the carrying and loading arm and has the guide bracket 12 and a scraper strip 13 for the compression straps.
- the suction opening 6 of the shoe 4 is opposite a cover surface 14, the contour of which is adapted to the curvature of the shoe and which is molded onto an insert 15.
- This insert piece encompasses a support rail 16 which extends along all of the drafting units of the ring spinning machine. A small distance is maintained between the cover surface 14 and the underside of the compression strap 7, so that the strap does not graze on the cover surface.
- the insert 15 is formed as a one-piece injection molded part. It consists of an upper plate 17 from which the cover surface 14 rises and a lower plate 18 in which a threaded bore 19 is arranged and two webs 20 and 21 connecting the two plates.
- the front web 20 opposing the material flow 3 the insert 15 is in one piece, while the web 21 opposite it is divided into two.
- the two parts of the web 21 are offset from the web 20 in the direction of the support rail 16 so that they do not cover it.
- the threaded hole 19 can be cut into the full lower plate 18, but it is also possible to inject a smooth hole by means of a pullable core and cut a thread in it.
- a clamping screw is screwed into the threaded bore 19, by means of which the insert 15, which can be displaced along the support rail 16, can be fastened in the functionally correct position.
- the front web 20 of the insert 15 opposing the flow of material advantageously has a cylindrical protrusion 24. Flight and fiber accumulations that could be deposited on this web are stripped down / out by the circumference of the lower roller of the output roller pair 2 of the drafting system rotating in front of this web, so that they cannot be drawn into the area of the material flow 3.
- the fiber structure compacted in this way is fed between the pair of rollers 8 to the downstream rotation zone, in which rotation is given to it, for example, by a ring / runner device and it is solidified into yarn.
