Definitions

  • the present invention relates to a method which is provided for the preparation of the matches for spinning by the spin spinning method.
  • the classic cardboard spinning process according to the current state of the art, however, brings with it a number of disadvantages which are caused by expensive work processes.
  • the classic carded yarn spinning technology is characterized by the relatively large, three-card set, which has a working length up to 25 m and a working width up to 3.5 m. This fact means that the fiber pile must be divided in a large number of narrow bands (300 and more) by the pile divider.
  • the fiber slivers are shown below by compressing and rounding off the fiber ribbons from the pile divider using the Nitzschel rollers.
  • the fuses are wound in the form of narrow coils by the winding device.
  • the finished bobbins are placed in the spinning machine, the slips are warped to a delay of 1.5 and then spun using the conventional ring spinning process.
  • a characteristic of this spinning process is the fact that the fiber sliver originating from the pile divider experiences a delay in the spinning machine which does not exceed 1.5 and is in any case sufficiently small so as not to change the fiber arrangement present in the sliver.
  • the pile divider divides the fiber pile into longitudinal ribbons with a certain width, which means that the yarn number range in which it can be produced is relatively small.
  • the expansion of the yarn fineness beyond this predetermined fineness limit is not only associated with a change in the roller pitch, but the card must be adjusted and readjusted according to the new working conditions.
  • special maintenance measures must be taken;
  • strict quality controls have to be carried out, either manually or using complex and expensive electronic measuring devices.
  • the use of the pile divider also leads to the creation of a large number of defects in the finished yarn, which is the actual bottleneck of this spinning process.
  • the fibers used in the carded yarn spinning process are characterized by a relatively large scatter in the fiber length, so that the fiber collective consists of extremely long and relatively short fibers, which means that smooth, corrugated or fitted drawing rollers cannot be used, because of this already mentioned disadvantage with regard to the resulting fiber arrangement in the fiber structure and the lack of control of the short fibers in which irregular yarns inevitably arise when such fiber materials are used.
  • the present invention solves the previously mentioned disadvantage, whereby yarns are produced which, according to their structural yarn structure, can be called carded yarns, but are simpler and more economical than those produced with the current spinning system, with the advantage that the pile divider together with the Nitschelwerk and the winding device fail completely.
  • the activities of the transport and the intermediate storage of the fuses to the presentation in the spinning machine are also eliminated by the present invention.
  • the carded fiber pile is brought together in a single fiber band and subsequently presented to each individual drafting device of a spinning machine in which it is warped. is turned and the finished yarn is wound.
  • a device that after the dining point with. is equipped with a system of small rollers equipped with clothing, the task is to dissolve the fiber sliver, to even out, mix and then compress the resulting fiber flow, with the aim of forming a narrow fiber web that has the same fineness and fiber arrangement as that from the conventional three-card set, but with the advantage that the present invention makes a significant improvement in the versatility of the spinning process and the cost reduction, especially in personnel and transport costs, is achieved.
  • the spinning process is carried out by the sliver dissolving and the subsequent fiber flow compression by means of rollers equipped with clothing.
  • the fiber web formed is then drawn off and compacted, the fuse is turned and the finished yarn is wound.
  • the fiber sliver is prepared in the spinning machine by at least two small-diameter rollers, which are provided with card clothing, although this can also be carried out, if desired, with a system consisting of three or more similar rollers.
  • the present invention also relates to the required device for carrying out the method already described, which basically forms an individual spinning unit of the spinning machine and the spinning elements for the feed, the fiber sliver dissolving, the compression of the fiber flow, the merging of the fiber pile, the twisting of the sliver and the winding of the finished yarn contains.
  • FIG. 1 A complete spinning station according to the present invention is shown schematically in FIG. 1
  • FIG. 1A a variant of the feeding device of the sliver is schematically represented by the dining table and feed roller.
  • Figure 1B schematically shows a variant of the feeding device using the dining table and endless belt.
  • Figure 1C schematically shows a variant of the feeding and opening device of the sliver by means of double endless rims and a pressure roller.
  • Figure 2A shows a spinning station with the use of spinning nozzles and with the winding device for winding the finished yarn.
  • Figure 2B shows a schematic representation of another way of imparting twist twist.
  • Figure 2C schematically shows a spinning station using a coaxial spindle for the winding thread.
  • Figure 4A there is an implementation with a fourth additional roller, which is used for the dissolution and the double branching of the fiber flow to form two compression points.
  • Figure 5 shows a design with a funnel-shaped condenser at the exit of the spinning station to bring together the fiber web.
  • Figure 6 shows a device with an endless belt at the exit of the spinning station to bring the fiber web together.
  • Figure 6A schematically shows a floor plan of the device shown in Figure 6.
  • Figure 7 shows a compacting device of the fiber web using several pairs of disks.
  • Figure 7A shows a floor plan of the design shown in Figure 7.
  • Figure 8 shows a schematic representation with details of the compression zone of the fiber web, the subsequent compacting of the sliver and the subsequent stretching of the fiber sliver by using false wire nozzles.
  • Figure 8A there is a schematic representation with details of the compression zone of the fiber web, the subsequent compacting of the fuse and the subsequent stretching of the fiber structure by using endless friction tapes.

  • the working group consisting of the rollers (5) and (5a), are used to introduce the card sliver (14) into the drafting device, which consists of the opening roller (1) and the compacting roller (3), the rollers with a suitable saw tooth set, needle or other resolution elements are provided.
  • the compacting roller (3) has a peripheral speed equal to or slightly less than the take-off speed of the fiber web and 4 to 100 times smaller than the peripheral speed of the opening roller (1).
  • the good functioning of the carding rollers is crucial for the successful functioning of the present invention, since starting from the supply belt (14) with a belt weight between 0.5 and 25 g / m, a sliver with a similar fiber arrangement to that of the fiber web in the card is formed, with the advantage that the pile divider fails and the manual activities, including the mechanical aids necessary herewith, are reduced dramatically.
  • the take-off and compacting device of the fiber web (18) contains the take-off rollers (6), (6a) and (6b) as well as the working group consisting of the nitschel rollers (9) and (9a) for compacting and rounding off the fuse (19).
  • the working group for simultaneously issuing the twist and winding of the finished yarn (13) consists of the ring traveler (12) and the cop (11).
  • the sliver (14) which can come directly from the card, or from a preparation machine from the spinning process, is introduced through the rollers (5) and (5a).
  • the sliver is dissolved by the action of the trigger roller (1) in the manner as already described.
  • the resulting fiber flow is conveyed through the clothing (19) of the opening roller (1) to the compression point B, where the clothing of the rollers (1) and (3) are in the working position.
  • part of the fiber flow is held back by the clothing of the dissolving salts (1) and transported back to the feeding point.
  • the other part of the fiber flow is taken over by the clothing of the compacting roller (3) and forms in the process the fibrous web (18), which is removed by the drawing roller (6), (6a) and (6b) from the clothing of the compacting roller (3).
  • the Nitschel rollers (9) and (9a) take on the task of compacting the fiber web in such a way that the fuse is given a compact round shape.
  • the resulting fuse is fed through the rollers (10) and (10a) into the twist winding device, in which the fuse (19) is rotated by the spindle and the ring traveler (12) and the finished yarn is wound in the cop (11) .
  • Figure 1A shows an alternative solution for introducing the sliver (14), in which the lower feed roller (5a) of Figure 1 is replaced by the dining table (5b).
  • Figure 1B for example, another solution is offered, which differs from that in Figure 1A, in which the feed roller (5c) drives an endless belt (5d).
  • the aim is to make the fiber dissolving relatively energetic through the feed roller / dining table solution correspondingly more supple.
  • the solution shown in Figure 1C is proposed for the dissolving device, in which for the introduction and the first dissolution of the sliver (14), the feed rollers (5) and (5A) of Figure 1 by the Endless bands (5f) and (5f '), which are driven by the rollers (5e) and (5e), are replaced.
  • the pinch line Ao is formed by the pressure roller (1a) together with the blunted clothing (1).
  • the Endendbaendchen (5f) (5f ′) guide the tape through the clamping line Aol, where the dissolution of the original tape takes place.
  • the fibers freed in the clamping point Ao are carried through the clothing (19) to the compression point B, at which the final formation of the fiber pile (18) takes place.
  • FIG 2A shows an example in which the fuse is rotated using either the single nozzle or the double nozzle (30) and (31) using the false wire method.
  • the crossed friction bands (32 and 32b) could also have been used instead of the second nozzle.
  • Other twisting devices such as are currently used in false-wire texturing, could also have been used.
  • FIG. 2C Another example of the consolidation of the fuse and the formation of the finished yarn is shown in Figure 2C, in which the spindle with the filament spool for the winding twist can be seen.
  • the fuse (19) is compressed by the nitschel bands (9) and (9a), it is pressed by the upper rollers (7) and (7a) as well as through the lower rollers (8) and (8a), the take-off speed of which can be controlled, through the twisting component, consisting of the coaxial spindle (36) and the bobbin (37) for the winding thread.
  • the finished yarn is wound through the grooved drum (35), forming the cylindrical cheese (34).
  • Figure 3 shows an example of the stretching of the supply belt (14) and of the formation of the fiber web (18).
  • This device differs from that in Figure 1 by the use of the middle roller (2) equipped with the clothing (20).
  • the first step of the sliver dissolution takes place through the action of the first dissolving roller (1) and the additional roller (2).
  • the roller (3) fulfills the same compression function of the fiber flow as in Figure 1.
  • the carding roller (2) generates a higher peripheral speed than that of the opening roller (1).
  • the speed ratios and the clothing angle of the compacting roller (3) are in the same order of magnitude as for the compacting roller of Figure 1.

  • the clothing tips of the rollers (2) and (3) are in the working position, so that part of the fiber flow follows the direction of movement of the clothing (20) of the carding roller (2), while the other part of the fiber flow through the clothing ( 21) the compacting roller (3) is retained and the fibrous web (18) is formed.
  • the example shown in Figure 4 differs from that in Figure 3 by the fact that the additional roller (4) is still added in the drawing unit.
  • the additional roller (4) forms together with the carding roller (2) an additional carding point C, especially since the clothing tips of the clothing (20) and (22) of both cylinders are in the working position.
  • the roller (4) also forms a common tangent with the opening roller (1) at point D, in which the clothing tips are in the transfer position.
  • part of the fiber flow is diverted through the clothing of the carding roller (4) and reaches the transfer line D, as a result of which the clothing of the opening roller (1) is guided to the feed point of the supply belt (14) up to the fiber beard.
