Field of the Invention The present invention relates to a yarn picking and cutting device for a thread guide yarn shuttle particularly for a knitting machine or the like. [Prior Art] In the field of knitting machines, a yarn guide system called "Threading Needle Shuttle" and generally used for an assembly is known, and the assembly uses an adapted yarn grasping and cutting device. Equipped with a yarn guide for each yarn to allow the yarn supplied to the needle to be changed during feeding or falling during production. One of the assemblies of the thread guide shuttle is disclosed in the same applicant in, for example, ΕΡΑ 07802212.6. The yarn gripping and cutting device generally includes a retaining member having a laminated body defining a recess on the side that is adapted to receive the yarn to be grasped and cut. The retaining element is interposed between the -grassing element and the -cutting element and also has a laminated body facing the opposite sides of the holding element. The gripping elements and the retaining elements are resiliently loaded onto each other on opposite sides thereof. The holding member is movable relative to the cutting X piece and the gripping member in a direction of the constant movement from a yarn backup position (where the portion having the holding portion of the recessed portion protrudes from the front side of the gripping member and the cutting member) By the to-hold position (the portion of the retaining element having the recess is retracted between the gripping element and the cutting element). Properly positioned to receive will grip and tangentially hold the retaining element relative to the gripping element recess. In the backup line position, the recess is in a cut yarn. The yarn is designed to actuate the cross member and the cutting element across the 154345.doc 201144504 in the transition from the standby position to the holding position, the component is scratching The component is gradually retracted from the cutting element. At the end of this retraction, the yarn to which the retaining element engages is progressively dragged between the side of the retaining element and the side of the gripping element, thereby actuating it and the yarn is subsequently brought to the cutting element. The front side (which constitutes the blade) contacts and actuates its cutting. These yarn gripping and cutting devices generally have good reliability when gripping the yarn, and this reliability is mainly derived from the elastic load of the holding member and the gripping member. This elastic load required to ensure proper grip of the yarn can result in excessive stress on the yarn 'when the yarn is pulled between the sides of the gripping element and the side of the gripping element by the movement of the holding element, which may result in The yarn is worn or even broken during its grip. The yarn breakage is a big problem 'because it causes a loss of yarn on the part of the respective yarn guide and requires downtime and manual intervention by the operator to revert back to the machine The correct feeder. In practice, this problem has made it possible to use ultrafine yarns on knitting machines that use such yarn gripping and cutting devices. [Content of the Invention] The purpose of this month is "to obtain a yarn grabbing thread for a knitting machine or the like which is particularly useful for knitting machines or the like by effectively providing an excessive strain of the yarn during its grasping. And the cutting device solves the above problems. Within this aim, the purpose of the present invention is to provide a so that the ultrafine yarn can also be used on a machine using the above-described type of thread guide shuttle assembly. Yarn grabbing and cutting skirts. Another object of the present invention is to provide a device that can be derived from a yarn gripping and cutting device of the type known from 154345.doc 201144504 in a very simple manner. A further object of the invention is to provide a device that can be installed on a knitting machine without problems as an alternative to a yarn gripping and cutting device equipped with a currently available thread guide yarn shuttle assembly. It is understood that this object and these and other objects are achieved by a yarn gripping and cutting device, particularly for a threading guide of a knitting machine or the like, which comprises a laminated body for holding yarn One of the elements of the line having a recess adapted to receive one of the yarns to be grasped and cut on one of its sides; a gripping element respectively provided on the opposite sides of the holding element from each other And a cutting member; the retaining member and the gripping member are elastically urged toward each other on opposite sides thereof; the "holding member 70" is movable relative to the gripping member and the cutting member in a direction of movement - a backup line position (wherein the recess is at least partially disposed outside the grip 70 and the footprint of the cutting element to receive a yarn to be grasped and cut) the yarn spans the recess transverse to the actuation direction) Moving to a holding position (where the recess is contracted between the gripping element and the cutting element, and the loop is performed by pulling on the opposite side of the holding element and the gripping element) Holding of a portion of the yarn and cutting of the yarn by interfering with the yarn with the cutting member and vice versa, the assembly comprising a partition member interposed in the solid member Between the gripping element In which the holding of the stress limits of the yarn during the traction element between the gripping element. [Embodiment] It is further possible to describe from a description of a preferred but non-unique embodiment of the device according to the invention 154345.doc 201144504 by a non-limiting example in the sigma Other features and advantages of the invention will be appreciated. Referring to the drawings, the device according to the invention, generally indicated by reference numerals, comprises an element 2 for holding a yarn 3, a gripping element 4 and a cutting element 5. The holding element 2 has a laminated body having a gripping element 4 configuration on one of its sides adapted to receive a recess 6 of the yarn 3 to be grasped and cut and also having a laminated body To the side of the holding element 2 and with one of its sides facing one side of the holding element 2. The holding member 2 and the gripping member 4 are elastically urged toward each other on their side faces facing each other by the spring member or the elastic flexibility of the laminated body using the holding member 2 and/or the gripping member 4. It is also preferred that the cutting element 5 of a laminated body has its side facing the side of the holding element 2 opposite to the side facing the gripping element 4. The holding element 2 can be cut relative to the gripping element 4 The element 5 is moved in the direction of the coincident movement (indicated by arrow 7) to pass from one of the stocking positions of the yarn 3 to one of the yarns 3 to maintain the holding position. In the standby position shown in Figure 2, the retaining element 2 is disposed in a position suitable for receiving a position of the yarn 3 to be gripped and cut, at least partially located outside the space occupied by the gripping element 4 and the cutting element 5. 6. The yarn 3 is designed to be transverse to the actuation direction 7 across the recess 6^, in which the holding element 2 projects with its recess 6 from the front side of the gripping element 4 and the cutting element 5. (4) "(4)" in the description of the towel refers to the side of the solid part 2, the gripping element 4 and the cutting element 5 which are designed to be guided to the machine bed of the apparatus according to the invention, ie designed a side of the holding element 2, the gripping element 4 and the cutting element 5, which must be fed by the thread guide shuttle assembly, wherein the yarn guiding shuttle assembly is provided with one of its yarn guiding hooks according to the invention Device. In order to better explain the characteristics and operation of the device according to the present invention, in addition to the device 1, a diagram of the yarn guide 8 used by the device W is also shown in the drawings: Figure 2, Figure 3, Figure 4 FIG. 5 also shows the assembly of one of the needles 9 of the machine fed by the yarn guide from the assembly of the sinker. 1 and 5, in the holding position, the retaining element retracts the recess 6 between the gripping element and the cutting element 5. The holding member 2 can be actuated by a member of a known type (in other words, by means of a reference and a member described in EPA G78() 2212 6 herein) from the backup line position to the holding (four) position. The movement, between the continuous guiding member 2 and the opposite side of the gripping member 4 (four) yarn (four) =: the retention 'and the yarn 3 against the front side of the cutting element 5 is called: cut:: the blade of the jaw 5) The cutting of the yarn 3 as a result of the interference. During the pulling between the gripping element 4 and the cutting element 5, the side of the front side 5a of the cutting device 4 is opposite to the side of the recess 6 as a relative element = the present invention 'device i includes a partition The member u is inserted between the holding arms uT element 4 to limit the range of stress on the yarn 3 during its holding of the element 2 and the gripping element 4. 154345.doc 201144504 It is expedient to detach the separating member U from the holding element 2 and/or from the gripping element 4 before cutting the yarn 3 by the cutting element 5 to ensure that the holding element 2 and the gripping element are ensured before cutting thereof The effective capture of the yarn 3 between 4. More specifically, the above-mentioned partition member 11 is constituted by a projection 12 projecting from the side facing the gripping member 4 of the holding member 2 as an alternative. The projection 12 can be disposed on one side of the holding member 2 Not disposed on one side of the gripping element 4, or there may be two mutually mating projections on the opposite sides of the holding element 2 and the gripping element 4, one on the holding element 2 and one in the gripping On component 4. In the illustrated embodiment, the retaining element 2 has a portion h that engages the projection 12 during its transition from the backup position to the retaining position, except for the end of the stroke 'because the retaining element 2 is in its In the region facing the projection 12 when in the retaining position there is a recess and which defines the portion 2a at the front. Due to the recess U, the retaining element 2 is detached from the projection 丨2 before the cutting element 5 interferes with the yarn 3 in the recess 6 of the arranging element 2. Preferably, the projection 12 is formed by a stamping mark projecting from the side of the grasping element of the guiding holding member 2. 2. The apparatus according to the invention is designed to be used in particular in conjunction with an assembly of a yarn guide shuttle 8 to be mounted on a knitting machine. In such a circular knitting machine, the wire guide slave assembly is disposed between the ideal cylindrical faces of the needles of the 4; The same is shown in Figure 154345.doc 201144504. The related device is shown in Figure 154345.doc 201144504 for each of the yarns 3 - the channel 14 and the circle. The system is configured such that the actuation direction 7 is radially and generally horizontally oriented relative to the barrel. Each of the yarn guides 8 is movable parallel to the actuation direction 7 to pass a position from a standby position in which the passage 14 is in a rearward position relative to the bed, i.e., relative to the needle 9 of the machine (wherein its passage 14 is Towards the bed, ie to the forward position of the needle 9 of the machine and vice versa. As described in more detail in EPA 07802212.6, when changing from the standby line position to the working position, / (4) also. Vertically to the actuation direction 7, i.e. (if the machine is a circular knitting machine) moves parallel to the direction of the cylinder axis to pass over the needle 9. The operation of the device according to the invention is as follows. As shown in Figure 1, when the yarn 3 is fed to the needle 9 of the machine, 'the yarn guide 8 is brought to the working position to configure the yarn 3 to extend from the channel 14 to the 4th of the device 1' so that it spans the machine The bed table is such that it intersects the needle 9 of the machine along its virtual cylindrical surface. In this way, there is a rituality of the needle 9 of the machine which is moved during feeding or lowering and which is acted upon by the assembly of the considered yarn guiding hooks 8 to feed the yarn 3 fed by the thread guiding shuttle 8. . As shown in Fig. 2, once the needle 9 begins to grip the yarn 3, the holding element 2 previously brought to the holding position is moved into the standby position by its movement along the actuation direction 7. In this position, when the feed to the yarn 3 of the needle 9 of the machine is interrupted, the holding member 2 extracts the recess 6 at an appropriate position in front of the gripping member 4 and the cutting member 5 to receive the passage from the yarn guide shuttle 8. The crucible extends upwardly to the portion of the yarn 3 which is the last of the yarn 3 when the feed or drop is considered. In order to interrupt the feeding of the yarn 3 to the needle 9 of the machine, the guide yarn (4) is moved backwards to I54345.doc -II- 201144504 to the standby position. As shown in Figures 3 and 3a, this retraction places the portion of the yarn 3 extending from the channel 到 to the needle 9 of the machine in the recess 6. Thereafter, the holding member 2 is moved from the standby line position to the holding position. During this movement of the holding element 2, the yarn 3 placed in the recess 6 is gradually moved closer to the gripping element 4 and the cutting element 5. It should be noted that during the passage from the backup line position to the holding position, the holding element 2 engages with its portion 2& which is against the projection 12 and this engagement has the effect of separating the gripping element* from the side of the 7G piece 2 against which it faces. . The part & and the holding element 2 are highlighted. This engagement between P12 lasts almost until the interference of the yarn 3 against the blade of the cutting element 5 on the side before the cutting element 5 is formed. As shown in Fig. 4 and Fig., in this manner, when the gripping member 4 and the retaining member 2 are still separated by the engagement of the projection η against the portion 2a of the retaining jaw 2, the gripping element W and The yarn 3 is pulled between the holding members 2. In view of this fact, it is possible to effectively avoid the excessive stress of the twisted wire 3 which may cause the yarn 3 to be worn or broken' as a result of the loss of the yarn 3 on the portion of the respective yarn guide shuttle 8. And FIG. 5a does not, when the yarn 3 is about to meet the front side of the cutting element 5 (I7 blade), the portion 2a of the holding element 2 is disengaged from the protrusion η and thus the gripping element 4 is moved to almost abut the holding element 2 The yarn 3 is securely gripped between the gripping element* and the holding element 2. «When the holding 7L member 2 is moved from the holding position to the standby position during subsequent feeding of the same yarn 3, the portion 2a of the holding member 2 re-engages the projection 12' to separate the gripping member 4 from the holding member 2 and thus ensures Release of yarn 3. In practice, it has been found that the device according to the invention completely achieves the desired purpose 'because it effectively avoids any excessive stress of the yarn, _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It can also be used on machines that use an assembly of yarn guides that require yarn gripping and cutting devices. Another advantage of Kangben's January device is that it can be obtained by modifications that can be easily provided from conventional types of capture and (4) devices. The device according to the invention is conceived to be particularly useful for thread guides, but it can be used in conjunction with other types of tombs, νk, without thereby departing from the scope of the invention. Many modifications and variations are possible in such a structured farm, all of which fall within the scope of the accompanying patent application; all details can be replaced with other technically equivalent elements. The materials and dimensions used in the transaction t' can be any material and size according to the requirements and current state of the art.
