Definitions
- the invention relates to an apparatus and a method for producing effect yarns / twines on spinning machines, in particular ring spinning machines.
- Double and multiple drafting systems that feed controlled, programmed differently or uniformly warped fiber strands to one and the same delivery point in the area of a delivery roller pair have already been published in earlier years.
- Applied flames which are fed between two and more carrier threads, are also available in effect twisting machines, as used for example for coarse yarn numbers used. Disadvantages are the coarse spindle pitches, the small production units and the missing Faserabsauganlagen, so that these fine yarn (eg yarn numbers NM 30-70) are unsuitable. The production of effect yarns in large quantities is therefore not economically possible.

- the device described in DE'762 is due to the same inventor of the invention disclosed below.
- DE'762 is directed to a device for mixing roving for the production of fancy yarns which does not require a continuous roving. All rovings can be varied equally and it is possible to work with more than two rovings.
- the apparatus has at least two delivery mechanisms for a respective roving and a common output delivery plant, a guide device for bringing the rovings between the output delivery plant and the delivery mechanisms, a drive device for driving the delivery mechanisms with variable speed, and a control device for the individual control of the drives of the delivery mechanisms.
- the device is advantageous for the production of effect yarn or effect yarn. It is suitable for installation in spinning or twisting machines.
- the device is limited to the processing of different rovings. To produce flames in different colors, the rovings are fed by means of a 4-fold drafting system in stacks or at varying speeds.
- the device has a comparatively complicated structure.

- DE3206431 was filed in 1982 in the name of the Zinser textile machines AC and shows a process for producing a fancy yarn.
- a fiber band is wound around with at least one filament yarn.
- This wound sliver is warped by means of a drafting so that the filament yarn is torn.
- the sliver is then wound up with the roving twisted with filament yarn fragments. Subsequently, the twisted roving is warped on a ring spinning machine and turned to effect yarn.
- DE7071 16 has been deposited in the name of Rudolf Landwehr and concerns an effect twisting machine for the production of effect yarns such as loop, caterpillar or crimped yarns.
- the effect twisting machine two delivery mechanisms arranged one behind the other are used.
- the rear, slower delivery mechanism delivers the crotch thread or threads
- the front, higher-speed delivery mechanism delivers the thread (s) destined for loop or crimp formation.
- the resting on the front delivery roller pressure roller is provided with grooves through which the Crundfäden the rear delivery mechanism are transmitted.
- the device is designed only for the processing of threads.
- An additional delivery unit feeds roving, which results in the core thread after leaving it due to the relaxation in a thickening. It is a special device that has not been a commercial success to this day. One problem is that the device is suitable only for the production of the described special game.
- CH51 9039 was filed 1,970 on behalf of the Commonwealth Scientific and Industrial Research Organization and shows an apparatus and method for making a uniform yarn from at least two running slivers
- the slivers are fed separately from a feed point to a point of convergence and uniform at the point of convergence
- the apparatus further comprises means for cyclically varying the path length between the point of convergence and the feeding point of the fiber ribbons
- the embodiment essentially consists of a conventional spinning drafting device with a multiple drafting device, which is arranged so that it can supply a sliver to the runner of a spinning spindle, but the spinning drafting system is deviated to that extent ert that there is only one single spindle between every two drafting devices and in the middle between them.
- Another embodiment has only one drafting system, which is suitable for processing both yarns.

- An object of the invention is a process for the production of effect yarn, resp. Effect ply to show on a ring spinning machine and an apparatus for performing the method.
- a further aspect of the invention is to show a device which is suitable for use with existing, fully automatic spinning machines, in particular ring spinning machines, with a plurality of spindles (usually up to 1 200) and by their simple operation, thread guide and Monitoring stands out.
- a further aspect of the invention is to show a device which makes it possible to show fine ring spinning machines modified according to the invention for many variants of niche yarns including base flame, core game, core game with non-elastic filament, boucle yarn and other twisting effects.
- Another aspect is to show a device that leads to thread breaks no problematic Garnanphaseufitch, respectively.
- the affected spinning station is interrupted in a controlled manner.
- a solution of the problem is based on the fact that an effect twist with at least two carrier yarns and thickening (flames) of other fibers by means of a specially designed for respectively. converted ring spinning machine is produced.
- Ring spinning machines known from the prior art which are suitable for the production of effect yarns have one or more spinning stations, each with a drafting device, which serves to delay a roving yarn or a plurality of rovings.
- the spinning machines are designed so that the delivery speed of certain areas of the drafting units can be changed abruptly, so that the fibers forming the yarn are cumulated in a controlled manner. In order to avoid thinning, partly finds a controlled over-feeding, resp. Dinners take place. If the drafting system no longer supplies fibers, the spinning process is interrupted.
- roving is withdrawn via deflections from a roving roll and fed to a pair of abutting belts driven pulleys and tensioned by belt guides.
- a pair of delivery rollers which receive the stretched roving emerging between the belts and convey a spinning triangle located behind the delivery rollers.
- the fibers of the roving which until then have been oriented approximately parallel and stretched against one another, are twisted into a yarn by a metal ring (rotor) rotating on a circular path (ring) about a spindle.
- the twisted yarn to the yarn are wound onto a plugged onto the spindle spinning sleeve to a cop.
- the fibers originating from the drafting system form the actual yarn. Since the feed rollers, the belts and the delivery rollers of the drafting system have different conveying speeds, the fibers of the roving are pulled apart or drawn apart uniformly.
- the absolute and the relative conveying speed of the individual areas of the drafting system are influenced so that a discontinuous conveying of the fibers results and thickenings in the yarn occur.
- conventional fancy yarns however, the fiber supply is never completely switched off, otherwise the spinning process suffers an interruption.
- An effect yarn according to the invention essentially comprises two or more twisted carrier yarns having the same or different properties.
- the effect yarn comprises other fibers which are fed between the carrier yarns by means of a drafting system prior to twisting them. These further fibers have a uniform distribution in the longitudinal direction or are present in the form of local thickenings (flames). Further combinations are possible.
- the supply of the additional fibers is preferably controlled by means of a modified flame-forming device of a ring spinning machine.
- the carrier yarns are fed in the region of the spinning triangle to the cam forming process of a ring spinning station in a defined lateral distance from one another.
- the carrier yarns are fed to the spinning process via a carrier yarn guiding means and / or by means of a continuously or discontinuously driven pair of rollers.
- fibers of a roving are regularly or irregularly processed by means of the drafting system and likewise fed to the spinning process by means of a roller pair.
- the pair of rollers may be about the draw-off rollers of the drafting system or about another guide means, e.g. a separate pair of rollers or juxtaposed yarn guides act.
- At least one of the rollers has a specially profiled cross section which is suitable for receiving, guiding and / or clamping the carrier yarns.
- one of the rollers has two circumferential grooves, which are arranged at a distance from the carrier yarns and serve for non-pressing implementation thereof.
- the Stromalgestivesvoriques for adjusting the relative distance of the carrier yarns per spinning point on an eccentric.
- the eccentric can be deflected by turning about an axis which runs approximately perpendicular to the direction of the carrier yarns, in the lateral direction.
- one or more carrying devices are provided approximately above each drafting system of a ring spinning machine, which are suitable for receiving yarn packages with carrier yarn.
- the carrying devices are arranged so that they do not conflict with existing elements of the spinning device, in particular the Wanderbläser and the roving bobbins.
- At least two carrier yarns are each fed to a drafting system in the region of the spinning triangle controlled by means of thread guides.
- two or more carrier yarns are wound on the yarn packages, which reduces the number of carrier yarn packages required per spinning station to one.
- over or juxtaposed spools of thread can be provided with only one carrier yarn, but this is associated with a certain overhead and increased space requirements.
- the fibers supplied by the drafting system generally have no supporting function and are replaced in their function by the carrier yarns in whole or in part. Instead, the fibers fed in from the drafting system serve to produce effects, for example of an optical nature, in the form of thickened areas. or for the creation of color variations, or for influencing the physical properties of the resulting Game.
- the fiber supply by the drafting system depending on the effect to be achieved completely or only partially prevented, respectively. off.
- a control device resp. a yarn monitoring system, which automatically interrupts the supply of carrier yarn to the affected spinning station when breaking one of the carrier yarns.
- the control device has a rocker held in balance by the carrier yarns, which is operatively connected to a separator. If one of the carrier yarns, which are supplied in pairs per spinning station, breaks, the rocker is deflected so that the supply of the second carrier yarn is also interrupted in a controlled manner by means of the separating device.
- the control device is also preferably constructed so that the carrier yarns can be easily threaded, e.g.
- control device is designed so that the carrier yarns held in position during a yarn break, but the supply is interrupted, is.
- At least two additional yarn rolls are fed to the process upstream of the delivery rolls by means of yarn guiding and control mechanisms according to the invention.
- the carrier wheels are passed between the delivery rollers and then enter the spinning triangle where they become one due to the rotation of the rotor and the cop Twisted yarn and then wound up on the cop.
- the carrier yarns are primarily conveyed by the driven delivery rollers or other aids.
- the carrier yarns are aligned and spaced by means of the yarn guides so that fibers supplied by means of the drafting system at least partially reach between the carrier yarns before they are twisted together in a spinning triangle. As a result, the fibers fed into the draw frame in the spinning triangle become part of the resulting thread.
- a thread results which consists of the two carrier yarns and the uniformly supplied fibers from the drafting system.
- the total thickness of the thread results from the thickness of the carrier yarns and the amount of supplied fibers from the drafting system.
- a change in the amount of fiber supplied by the drafting system results in a yarn having a varying thickness.
- flames of different lengths and dimensions can be achieved.
- the drafting system itself which hitherto served for the actual, primary fiber feed, only has a secondary function, for example for producing yarn effects.
- the arrangement and presentation (preparation) of the feed yarns containing the carrier yarns is preferably arranged below the existing Vorgamaufsteckung on the drafting system. An impairment of the Wanderbläsers can be avoided. Another advantage is that these components can easily be installed in existing spinning machines in this way, without them having to be massively changed.
- Guide separators position the applied feed bobbins in the longitudinal direction of the carrier cylinder and enable a non-contact parking position relative to the carrier cylinder (s).
- one or more carrier cylinders (feed cylinders) positively driven in an adjustable ratio to the delivery rollers of the drafting system carry the carrier yarn packages.
- the carrier yarn bobbins lie along a lateral surface at least in regions directly on at least one carrier cylinder or are in operative connection therewith.
- the carrier yarn bobbins can rest on two support cylinders lying one behind the other at the same time. Laterally, the original coils are supported and guided by means of guide separators.
- the guide separators have further guide means for the carrier yarn bobbins, which are suitable, for example, for receiving an axle or an axle stub of the carrier yarn bobbin, respectively.
- two guide separators arranged opposite one another have obliquely or vertically upwardly extending guide grooves approximately radially to the carrier cylinders, which are aligned in the axial direction with respect to one another such that they are suitable for receiving an axis of a carrier yarn package.
- the guide grooves in the rear, facing away from the carrier cylinder, area a saddle surface in which the axis of the carrier coil can be brought into a parking position, so that the carrier yarn spool is no longer in operative connection with the carrier cylinder.
- variable stretching zones can be provided between the carrier cylinder and the delivery rollers of the drafting system, by means of which the tension and the warp of the carrier yarn can be adjusted.
- the tension of the carrier yarn is compensated by the support cylinders upstream, arranged parallel or obliquely to these ironing.
- the stirrups have an area which, during the unwinding of the carrier yarns, is in contact with them in a manner clock stands.
- This area of the bracket has approximately the width of a carrier yarn bobbin.
- the stirrups can be operatively connected to a triggering mechanism by means of which the carrier yarn spools can be lifted out of a parked position with a simple handle and brought into the working position. Good results are achieved by the trigger mechanism acting on both sides of the stub axle of the carrier yarn package.
- the carrier cylinders are preferably arranged in pairs one behind the other and parallel to the longitudinal direction of the spinning machine (transverse to the spindles). Depending on the machine type, there are the possibilities of designing the carrier cylinder or cylinders so that they extend only over certain areas or over the entire length of the spinning machine.
- the carrier cylinders are preferably driven laterally and rotate substantially at a constant speed, which is tuned relative to the conveying speed of the delivery cylinder of the associated drafting equipment or so, so that an optimal supply of carrier yarn is ensured.
- the drive speed is adjustable within a certain range (e.g., +/- 5%) so that different conditions and yarn tension can be accommodated.
- the carrier cylinders are driven intermittently, whereby the carrier threads in the pair of take-off rollers are not clamped (e.g., roller with circumferential grooves) and the pulling direction of the traveler and the cop causes the trigger. This variant allows loop, knot and Bouglet monoe to produce on ring spinning machines.
- the carrier cylinder may also consist of several segments which are operatively connected at their ends. This allows maximum flexibility, eg when retrofitting or when wearing out occurs.
- the support cylinders can be ideally matched to the carrier yarn to be processed.
- the segments of the carrier cylinders are operatively connected by means of connecting elements, which also serve as bearing elements by resting with a rotationally symmetrical outer surface on one or more opposite the spinning machine supported guide rollers.
- the carrier cylinders may have traction-increasing surfaces, for example in the form of corrugations or coatings.
- the supply spools are prefilled, i. they contain two or more parallel stored carrier threads. If necessary, it is possible to provide one or more pairs of carrier yarns on a supply spool. Thus, several spinning stations can be operated from only one feed bobbin. This offers the advantage that the number of required carrier yarn spools can be reduced. Another advantage is that very little space is required, so that the device itself is suitable for use on ring spinning machines intended for cotton with a very narrow pitch (distance between individual spinning stations) of around 70 to 82.5 mm. If there is more space, it is possible to use two single carrier yarn bobbins instead of a preformed carrier yarn bobbin. The defined delay between the delivery roller of the drafting system and the at least one feed cylinder controls the desired tension and compensates for voltage fluctuations.
- One embodiment has a carrier yarn guide, which is arranged in the region of the take-off rolls. About a holder, the carrier yarn guide is attached to Vorgam Traversierprofil the ring spinning machine. This ensures an optimized synchronization of the carrier yarns and the roving.
- Another aspect is an active monitoring of the carrier yarns by means of a
- Thread monitoring system which is preferably arranged in front of the delivery cylinder.
- the thread monitoring system checks whether all carrier yarns required for the spinning process are ne are effectively present. If one of the carrier yarns is missing, it leads to a discontinuation of the spinning process, for example by also controlling the supply of the remaining carrier yarns in a controlled manner or by means of a drive of the supply reel.
- a thread monitoring system usually includes a thread sensor and a thread separating device which cooperates between the supply spool and the delivery roller of the carrier cylinder with the carrier yarns. The position is preferably synchronized with the fiber material flow in such a way that the integration of the fiber material supplied by means of the drafting system of the spinning machine is optimized, eg to form a flame.
- a mechanical embodiment of the yarn sensor works with the thread bias.
- a spring-biased rocker which can be deflected symmetrically to the left and to the right, the presence of the filaments is controlled by virtue of the prestressing of the filaments holding the rocker in a central position. Now missing one of the two carrier threads, the bias of the permanent thread is sufficient that the rocker is deflected so that the remaining thread is interrupted. Without carrier threads, it is ensured that no wrong yarn is spun. If necessary, the center position of the rocker can be ensured by means of suitable centering elements in a defined manner until reaching a certain deflection force.
- this is achieved by means of a magnet which exerts a force on the rocker in the middle position which is sufficiently large that the rocker does not deflect uncontrollably even in the case of vibrations or vibrations.
- the size of the force can be adjusted in this embodiment, for example by means of the distance between the magnet and rocker.
- a thread sensor according to the invention is preferably characterized by a simple threading capability. Alternative embodiments are possible.
- An essential aspect is the easy threading of the carrier yarns on the running spinning machine.
- a Clutica is arranged in the range of withdrawal rollers in distance and / or alignment finely adjustable. Depending on the embodiment, it is iridescent (laterally deflecting) on vorgam traversing or fixed with respect to the delivery rollers.
- a supply of the effect-forming fibers preferably takes place via a modified basic flame plant.
- This contains a programmable controller for the desired types of flame shapes and flame sequences.
- a feature consists in an adapted feed movement of the drafting system by means of adapted ramp during startup and braking. Expediently, the feed is accelerated in the beginning and after the formation of flames, the feed drafting system is not only braked, but also turned back a bit so that residual fibers, which lie with the tip in the area of the delivery cylinder clamping point, are not entrained between the flames and thus cause fiber contamination , As it has been shown, the operation of the spinning machine in normal production mode (running state) for normal spinning is well feasible.
- a special delivery cylinder contains on both sides of the pendulum carrier a lifting device, eg in the form of an eccentric support roller, which is in the activated state the pressure roller is lifted apart one at a time, while the second pressure roller can continue to work in the correct position, thus achieving the goal that all running processes per spindle can be interrupted.
- kits for converting a commercially available ring spinning machine comprising essentially a carrier yarn bracket for receiving at least one carrier yarn bobbin per drafting of a spinning station.
- the kit further includes a carrier yarn guide adapted to the carrier yarn holding device for feeding at least two carrier yarns spaced apart from one another in the region of a pair of rolls arranged in front of a spinning triangle.
- the carrier guide of the kit may have an inner guide, which serve for deflecting the carrier yarns in front of the spinning triangle.
- carrier yarn holder has a carrier cylinder arranged in the longitudinal direction of the ring spinning machine and rotatably driven about its longitudinal axis, which is in operative connection with at least one carrier yarn bobbin of a spinning station during the spinning process.
- the carrier cylinder is in this embodiment during the spinning process with a lateral surface of the carrier yarn in operative connection.
- a lift-off device is present per carrier yarn bobbin which serves to temporarily interrupt the operative connection between carrier yarn bobbin and carrier cylinder by decoupling the carrier yarn bobbin from the drive.
- the lift-off device can be arranged rotatably about the carrier cylinder or another axis. In one embodiment, it has a crescent-shaped cross section.
- the support cylinder of several normalized segments whose ends can be operatively connected directly to each other or via intermediate elements, the length can be adjusted flexibly on different ring spinning machines.

- the carrier cylinder can serve to drive carrier yarn packages of several spinning stations.
- a carrier yarn spool it is possible to wind on a carrier yarn spool several pairs or groups of carrier yarns. As a result, the number of carrier yarn rolls can be reduced, respectively several spinning stations can be operated simultaneously from one carrier yarn roll.
- problems may arise in breaking a carrier yarn.
- a corresponding adapted winding device is provided, which is equipped with a winding head which makes it possible to wind the required number of pairs or groups of carrier yarns on a carrier yarn bobbin. If necessary, the winding head is designed so that the plurality of carrier yarns are adjustable in their distance relative to each other.

- the carrier yarn guiding device 38 is designed so that the carrier yarns 32 are fed to one another in a fiber delivery region 52 at a defined distance a (see FIG.
- the Rushgam Equipmentsvoriques 38 may be formed so that the distance a can be adjusted.
- Figure 4 shows detail C of Figure 3 in an enlarged view. Evident are the drafting 3 with the feed rollers 4, 5, the delivery rollers 8, 9 and the interposed belt 1 3, 14.
- the Gam Operationss- and monitoring device 38 is mounted in the embodiment shown by means of a bracket 40 on a laterally deflectable Traversierschiene 41 by means of the yarn guide device 38, and arranged behind the drafting 3 Vorgarnation (ceramic guide) 24, laterally moved back and forth ( schematically represented by arrows F). As a result, uneven wear of the delivery rollers 8, 9 is counteracted. If necessary, the yarn guide devices 24, 38 may also be fixed.
- the Taversierschiene 41 is a holder which is arranged behind the drafting systems usually runs parallel to the machine longitudinal direction.
- a yarn 22 of the type according to the invention typically has at least two carrier yarns 32 twisted together, between which further fibers 21 from the drafting system 3 are interwoven.
- the further fibers 21 may be incorporated in the form of flames 23 (local thickenings) or continuously.
- the carrier yarns can be decoupled from the take-off rolls by providing the take-off rolls with tangentially circumferential grooves (not shown in detail) in which the carrier yarns 32 are arranged.
- the circumferential grooves reduce local traction.
- the inner surfaces of the grooves may be provided with a friction reducing coating.
- separate rollers can be arranged in the grooves, which can be rotated independently of the take-off rolls.
- the carrier yarn guides 38 are arranged rigidly and not deflected laterally or the take-off rolls 8, 9 deflected together with the traversing rail.
- FIG. 5 shows a mechanical Shingam arrangements- and monitoring device 38 according to the invention in a front view (x-direction).
- the illustrated embodiment is constructed so that the carrier yarns 21 can be quickly and easily fed from the front along a first and a second fiber guiding portion (fiber guiding path) 51. Especially in ring spinning machines with large spindle numbers, this is particularly relevant for economical operation.
- the Rushgam Equipmentsvoriques 38 is constructed so that the carrier yarns 32 are discharged at a defined distance a.
- the guide device can be constructed so that the distance a is adjustable.
- an active monitoring of the carrier yarns 32 by means of a yarn monitoring system 38 is important so that, in the event of breakage of one of the carrier yarns 32, the remaining carrier yarn is no longer conveyed and leads to a disruption of the spinning process.
- the thread monitoring system 38 checks whether all necessary for the spinning process carrier yarns 32 are effectively present. If one of the carrier yarns 32 is missing, it leads to a discontinuation of the spinning process by also controlling the supply of the remaining carrier yarns 32 in a controlled manner and returning them to the associated carrier yarn package.
- a thread monitoring system usually includes a thread sensor and a thread separating device which cooperates between the supply spool and the delivery roller of the carrier cylinder with the carrier yarns.
- the position is preferably synchronized with the fiber material flow in such a way that the integration of the fiber material supplied by means of the drafting system of the spinning machine is optimized to form a flame.
- the illustrated mechanical embodiment of the yarn sensor 38 operates with the bias of the carrier yarns 32.
- the yarn sensor 38 has a base plate 44 and a means of a spring (not visible) biased about an axis 42 rotatably mounted rocker 43. Since the rocker 43 can be deflected symmetrically to the left (FIG. 5b) and to the right (FIG. 5c), the presence of the carrier yarns 32 is controlled by the carrier yarns 32 being in a middle position (FIG. 5a) due to their prestressing. hold.
- the bias of the remaining carrier yarn is sufficient that the rocker 43 is deflected so that the remaining thread is interrupted.
- the rocker 43 has cutting blades 44 which separate the carrier yarns 32. By interrupting the carrier yarns 32 ensures that no wrong yarn is spun.
- the center position of the rocker 43 can be ensured by means of a suitable centering element in a defined manner until reaching a certain deflection force. In one embodiment, this is achieved by means of a magnet which exerts a certain force on the rocker in the center position, which is sufficiently large that the rocker does not deflect uncontrollably even in the case of vibrations or vibrations. The size of the force can be adjusted in this embodiment, for example by means of the distance between the magnet and rocker.
- FIG. 6 shows a further embodiment of a ring spinning device 1 according to the invention, obliquely from the front and from the top.
- FIG. 7 shows detail D from FIG. 6.
- the variant shown in FIGS. 6 and 7 has a simplified carrier yarn guide device 45, which consists of a guide element 46 with two carrier yarn guide channels 47, 48 arranged next to one another.
- the guide element is formed in one piece here and has a substantially E-shaped cross-section.
- the carrier yarn guide device 46 is configured such that the distance between the carrier yarn guide channels 47, 48 is adjustable. If one of the carrier yarns 32 breaks, the yarn feed is not interrupted.
- the Austen operationsvorraum 46 is attached via the bracket 40 to the Traversierschiene 41 and is moved by means of this during operation in the y-direction back and forth so that the delivery cylinders 8, 9 are not worn unevenly.
- the guide element 46 is arranged on a base 49, which preferably consists of plastic.
- the base is designed to be flexible and can be easily mounted on the bracket 40, for example by clipping or clamping.
- the Swissgam operationsvortechnisch 46 is preferably made of an abrasion-resistant material, such as ceramic or hard metal. The device can be further simplified if the Collinsgam Equipmentsvortechnisch 46 is not arranged on a Traversierschiene 41 but stationary.
