Definitions

  • the present invention refers to a weft yarn operating device in a gripper loom, without formation of a false selvedge on the feeding side of the weaving loom.
  • the weft yarn operating device according to the present invention can also be used in a projectile weaving loom, wherein the projectiles are provided with a weft yarn grip-and-release function on the running projectile, for example as disclosed in European patent application No. 18176734.4 to the same Applicant.
  • false selvedge is meant to indicate a group of additional warp yarns placed at both sides of the warp yarns intended for the formation of the fabric and at some distance therefrom, said warp yarns being interwoven with the weft yarns often by a simple cloth weave, said cloth weave thus differing from the weave with which the fabric is produced.
  • One object of the false selvedge is to form an area of perfectly stretched weft yarns between the regular warp yarns and those of the false selvedge, on which area a special cutting device can act that separates the false selvedge from the fabric once the fabric is regularly woven, and then at a distance of a few centimeters from the beating line, so that the resulting edge of the fabric, and in particular the weft tail fringe bounding the same, is perfectly regular.
  • another object of the false selvedge is to operate the weft yarn tying function, during the insertion step, thanks to a shed closing mode independent and preferably anticipated in respect to the regular warp yarn closing mode, to fasten the two ends of the weft yarns while they are perfectly stretched and thereby avoid any weft defects in the fabric.
  • Yet another object of the false selvedge is to be the connection point for the waiting weft yarns, as better illustrated below.
  • a further object of the false selvedge is to be able to use therein warp yarns having physical characteristics differing from those of the warp yarns of the fabric, i.e., that are more suitable for achieving a strong and stable tying of the weft yarns and a stable fastening for the waiting weft yarns.
  • weaving loom feeding side it is meant the side from which weft insertion occurs, which almost always corresponds to the left side of the weaving loom relative to the position usually taken by the weaver.
  • the false selvedge is typically used, on the feeding side of the weaving loom, to maintain the physical connection between the weft yarns waiting to be weaved and their respective feeding devices, and to allow the carrying gripper to grip them.
  • the weft yarns Upon insertion in the shed, the weft yarns in fact are not cut but remain connected to the fabric on one side - running parallel to the edge of the fabric and being held close to the same by a special guide hook - and to the weft feeding device on the other side, by means of the levers of the weft selector device.
  • Weft cutting then occurs upon selecting a new weft yarn, and precisely after the weft yarn - which is being held stretched between the weft selector device and the edge of the fabric - has been gripped by the carrying gripper and before the same be brought by the carrying gripper inside the shed.
  • EP 240075 to PICANOL discloses a solution whereby the various weft yarn clamping grippers are parallelly arranged, at increasing distances from the edge of the fabric being woven.
  • Said clamping grippers are movable between: a rest position; a weft presentation position, in coordination with the weft selector; and an alignment position with the fabric line where reinsertion of the beating weft in the respective clamping gripper occurs, by means of a corresponding hook integral with the reed.
  • Said hooks are thus also arranged parallel to each other, at increasing distances from the edge of the fabric being woven and are also of increasing lengths to adapt to the different clamping positions of the individual clamping grippers.
  • each clamping gripper must necessarily have a dedicated control, and one that, in addition, only fully solves the problem for the clamping gripper that is closest to the edge of the fabric, given that, for the next clamping grippers, there still occurs a weft waste of increasing length.
  • the different weft-to-weft gripping geometry caused by the difference in length of the series of hooks arranged side-by-side, could cause problems with the proper gripping of the weft by the carrying gripper.
  • US 5492153 to SULZER published in 1995 , discloses an improved solution to the same problem, whereby the clamping grippers are arranged in a single block and are superimposed on each other in a vertical plane adjacent to the edge of the fabric being woven.
  • a first motor control moves the clamping gripper of the weft of interest toward the fabric line;
  • a second motor control opens said clamping gripper after the weft of interest has been inserted in the shed, to enable reinsertion thereof into the clamping gripper by means of the beating reed.
  • Reinsertion operation is facilitated by a guide plate provided with a central guide slot, inside which the newly beaten weft yarn is drawn by the movement of the reed.
  • this solution allows the weft waste problem to be completely overcome since all the active clamping grippers are brought in the same position, next to the edge of the fabric. From a textile point of view, however, this solution has a significant drawback in that it does not allow a constant tension of the waiting weft yarns to be maintained, since the length of their path varies according to the successive movements of the clamping gripper block. There is therefore a frequent possibility of loosening the waiting weft yarns, which may cause both a failure by the carrying gripper to grip the weft yarns and a mutual entanglement of the weft yarns, which actually lie very close to each other.
  • weft clamping grippers are arranged in series and are maintained in the closed position by a single common spring, an independent adjustment of the clamping force cannot be achieved for every single clamping gripper, as is often desirable in the presence of different types of wefts.
  • the problem addressed by the present invention is therefore to provide, in a gripper loom, an operating device for the waiting weft yarns allowing for the same results to be achieved in terms of mechanical simplicity, as well as precision and consistency of the weft tail cutting length, as those provided by the solution illustrated in the above-mentioned Sulzer patent, without experiencing the drawback of a change in length of the waiting weft yarn path as the clamping grippers switch position, which may consequently cause the loosening of the weft yarns and result in defects in the fabric.
  • a first object of the present invention is therefore to propose a weft yarn operating device allowing for different clamping grippers to be alternated before a same work station, next to the fabric being woven, and in alignment with the fabric line, without this leading to any substantial variation in the path length of the weft yarn length between said clamping grippers and the relative weft feeding device.
  • Another object of the present invention is to provide a weft yarn operating device in which any possible interference between the waiting weft yarns is also actively avoided. This problem is solved, and these objects are achieved, by means of a weft yarn operating device having the features as defined in claim 1. Other preferred features of such a device are defined in the secondary claims.
  • a weft switch plate S having the general shape of a circular sector rotating about its rotation axis C, as shown schematically in Fig. 1 .
  • four weft yarns 1-4 are shown starting from pre-feeders F, each passing through a respective lever of a weft selector A and finally reaching single clamping grippers P that are arranged, as above stated, along an external circumference of the weft switch plate S.
  • the number of wefts that can be managed by the device of the invention is only limited by the size of the switch plate S on which clamping grippers P are mounted in a number equal to the different wefts to be processed. Therefore, although, for ease of representation, the invention is shown in the drawings with respect to the number of four wefts, it should be understood that the number of wefts processed by the device may be any number equal to or greater than two, with the upper limit of processed wefts being determined exclusively by the mechanical bulk and by the need to maintain an adequate separation between the wefts, as will be better illustrated below.
  • each clamping gripper By rotating weft switch plate S about its rotation axis C, each clamping gripper can be positioned near work station L, next to the edge of the fabric, in a retracted position (with respect to the forward direction of reed R) relative to beating line B, where the weft yarns are beaten by reed R against the fabric being woven ( Fig. 9 ). Virtually in the same position, and in any case before reed R reaches the beating line B, the weft cutting is also performed.
  • each weft yarn T is associated with one, and only one, clamping gripper P; that work station L, where the weft gripping and cutting operations take place, is one and the same for all clamping grippers; and that weft switch plate S is rotated to position at side work station L the clamping gripper P associated with the weft yarn being selected for insertion by weft selector A. It is therefore apparent from the foregoing that the control of weft switch plate S is logically connected to the control of weft selector A.
  • each individual weft path is precisely defined by means of a specific weft guide device that will be described below.
  • the drawings of Figs. 2 to 8 show a preferred embodiment of the mechatronic device implementing the solution principles described above. This device consists of three main functional groups, namely a weft switching unit, shown in Figs. 2 to 5 , a weft cutting assembly that operates before the reed beating, shown in Figs. 7 and 8 , and finally a separate element for positioning and holding the weft yarn during the insertion step, shown in Fig. 6 .
  • the weft switching unit comprises a weft switch plate S, having the circular sector shape shown above, hinged on a shaft 1, which rotates relative to axis C and is driven to rotate by a main motor Ms through an articulated quadrilateral 2.
  • a main motor Ms which is preferably a position-controlled electric motor
  • the rotation of the main motor Ms is controlled by the central control unit of the weaving loom so as to bring into work station L the clamping gripper P associated with the weft yarn being activated from time to time by the weaving loom selector A.
  • Clamping grippers P are positioned on weft switch plate S along a peripheral circumference arc thereof, whose center lies precisely on rotation axis C.
  • Opening controls 3 of said clamping grippers P acting in contrast to retaining means (for example, spring means or magnetic means) which usually keep clamping grippers P pushed in their closed position, are arranged in the upper part of weft selector S. Opening controls 3 are actuated by a single actuator Mp, preferably a force- or position-controlled linear motor, or even by a simple electromagnet which is provided in a fixed position relative to the weft switch plate S. This fixed position is selected so as the actuator Mp is apt to operate the opening control 3 of a clamping gripper P when, following rotation of weft selector S, this last has been moved into work station L.
  • retaining means for example, spring means or magnetic means
  • the working cycle of the switching unit is then restarted, and the weft switch plate S is either rotated to position the next desired weft yarn, and relative clamping gripper P, into work station L, or remains in its current position if a new insertion of the last inserted weft is expected.
  • a comb-like yarn guide 4 for separating the wefts, which is integral with shaft 1 of weft switch plate S and projects downwards from it, as clearly shown in Fig. 4 .
  • the comb-like yarn guide 4 consists of a plurality of parallel bars 5 having a cylindric cross-section, sufficient in number to define as many gaps as the processed weft yarns, with the purpose of maintaining the weft yarns well separated from one another and therefore avoiding any entanglement or relative rubbing therebetween, while leaving a full freedom of linear movement to the same weft yarns.
  • Bars 5 are arranged in a circular cylindrical configuration having an axis that coincides with rotation axis C of the weft switch plate S and a radius small enough to render negligible any variation in the path length of the waiting weft yarns during rotation of weft switch plate S, and therefore of comb-like yarn guide 4, so as to control any possible corresponding loosening of the weft yarns within an acceptable range.
  • the comb-like yarn guide 4 then operates in cooperation with a pair of plates 6 and 7 (removed, for greater clarity, in Fig. 4 ). Plates 6 and 7 are separated from each other by a weft yarn transit channel, and perform different functions, and specifically:
  • a further element of the weft yarn operating device of the invention useful for the proper operation of the device when negative-type carrying clamping grippers are being employed in the weaving loom, is the so-called weft leveling plate.
  • This element is physically distinct from the weft yarn operating device of the invention but is closely linked thereto from a functional point of view, as will be better understood from the following description.
  • leveling plate a mechanical element fixed on the weaving loom, at the shed inlet, which is provided with a weft yarn sliding surface and is adapted to ensure that the weft yarns being selected and lowered by weft selector levers A are kept at an appropriate and constant height, suitable for allowing the correct gripping of said wefts by the carrying gripper G, regardless of which lever of the weft selector has been lowered.
  • the wefts thus lying on the weft leveling plate slide thereon during the carrying gripper G initial run, until the tension of the weft yarn becomes such as to allow negative clamping thereof by the carrying gripper G.
  • the correct acute-angle arrangement of the weft yarn in respect of the carrying gripper G, during the clamping operation is determined by the presence of the traditional cutting device.
  • the usual mounting position of this device on the loom i.e. close to the trajectory of the carrying gripper G, provides a weft yarn supporting point during the initial run of said gripper, allowing the weft yarn to be inserted into the gripper according to the preset and correct angular position.
  • the forward end of the weft leveling plate 9 is provided with a hook 10 having a narrow, elongated V-shape.
  • the weft yarn slides on the weft leveling plate until it is hooked into the hook 10, thus achieving a suitable support and rotation point for the correct angular positioning of the weft yarn, and hence an effective gripping of the weft yarn by the negative carrying gripper G.
  • the weaving loom is equipped with a positive carrying gripper, obviously it is not necessary to have hook 10 on leveling plate 9, since in that case the gripping timing is determined by the same positive carrying gripper. It should be apparent from the foregoing description that the weft yarn operating device of the invention has fully achieved the preset objects and solved the underlying problem of the invention by providing a device which do not need a false selvedge and, moreover, is particularly compact and completely free from the drawbacks of the prior art devices of this type.
