DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for mechanically splicing textile yarns, and also to a splicer apparatus suitable for mechanically splicing style yarns in accordance with the method. .

More precisely, the present invention relates to a method and apparatus suitable for untwisting and then reconstituting textile yarns and for slicing two yarns together by performing the entire mechanical process.

Air-actuated slicer devices are known, in which the fibers of the yarns are separated and mixed, so that the yarns are then sliced together.

Mechanical splicer devices of the type that produce other types of fisherman's knots are also known.

Mechanical splicing devices are known which operate by rolling (de5lit%y) the yarn between two elements that rotate and roll or slide in mutually opposite directions.

To enable the tails to be coupled and rekindled, the Porter must hold and bring together the tails that would otherwise fly around.
Comb and use 5tationary aomp).

However, the flare-up effect is problematic and uncertain. This is because if a flare-up is to be performed, it is assumed that the tails are truly fixed together.

However, the fixation is not strong enough. This is because it can only be attempted by the static pressure of the comb.

The static pressure of the comb also causes a delay in the application of the twist, especially when the twist is applied to both tail ends and on the tail end.
I am absolutely certain that I will not be found to be a counterfeiter.

8IRO)% known. This involves untwisting each yarn section, tearing it from the yarn to form two tail ends, coupling the tail ends, and retwisting the tail ends to form a splice. The tail end is clamped at gripping points spaced apart to define specific tracts of the yarn to be untwisted; after the formation of two twisted friend turns that remain locked between the separated gripping points and at least a portion of the tail cooperating with at least two of the separated gripping points. Includes splicing apparatus and methods.

The present invention is particularly useful for yarn understanding between surfaces moving in opposite directions.

The present invention provides auxiliary cooperating means (awi) for cooperating with said surface.
Liary partiaipating means
). For the sake of simplicity and clarity, in the following description we will only deal with the case given as an example consisting of opposite rings, rings that are substantially and at least momentarily concentric with the pairs of blocks, tapes, yarns. It may be replaced by a pair of small rings or other similar means which can be used substantially for that purpose.

The known Meig mechanical splicing device is suitable for controlling the tracts to be sliced and is related to the present invention, in which one splice and the tail are uncoiled.
'L(S%5uosnd) End block tsft)
It is associated with significant disadvantages with regard to the nature of the knot and the inconsistency and composition of the knot itself.

The joint is made by untwisting the yarns to the desired value, coupling them in the untwisted state, and then coupling so that the fibers of one yarn join the fibers of the other yarn. obtained by rekindling.

In other words, the present invention utilizes the positive twist originally contained in the yarn (poaiti%--from the achievement of parallel or substantially parallel fibers at the end of untwisting, at least in the tracts to be twisted). ) to advantageously obtain a range of untwisting f' up to the achievement of a negative twist of the same or greater magnitude.

By untwisting or d-rekindling is meant the respective action of removing twists present in the yarn and of a*mct-reconstitution.

Therefore, untwisting is defined as a negative twist up to about a value of zero or beyond a value of 41 or possibly greater than or equal to the initial positive twist.
It means the action of completely removing the twist until 111 is given.

Also, rekindling means the operation of rearranging the twist in a threaded yarn, such that the twist at the end of the rekindling is the same or almost the same or greater than the original twist. I can do it.

The proposed method and the device associated therewith make it possible to obtain fast and clean joints without end tact and in any case with a tensile strength If? at least equal to that of the remainder of the tar. It also makes it possible to obtain a stable and strong joint that can be ensured.

According to the invention, the yarns can advantageously, but not necessarily, be parallel between the facing ring means at the beginning of this procedure, or they can be located mutually or intersectingly or apart.

The mutually facing ring means have friction surfaces which are at least biased against the yarn at the desired pressure and are capable of applying a tangential force to the yarn when set in rotation. .

The yarns are inserted between the opposing ring means of the slicer device by already known and therefore non-complicated means, and then the ring means are approached towards each other until they come into contact with the fibers at the desired pressure. and then rotated in opposite directions to each other, both of them being rotated in a direction opposite to the direction of winding of the yarn, so that a negative twist of the desired degree and value is generated in the yarn itself.

When the desired degree of negative twist in the yarns is almost obtained or obtained, the yarns are substantially in contact and substantially parallel to each other, one of them possibly having an advantage over the other. A process is employed in which the yarns are brought together so that they are pressed together.

When the yarns come into contact, and after they have come into contact with each other, auxiliary separation of the fibers by auxiliary associated means can occur.

Said auxiliary separation occurs as a result of the action of suitable means such as combs, cold liquid sheds, hot liquid sheds, treated liquid or treatment liquid sheds, brushes, needles or other similar or hybrid means. be able to.

The auxiliary associated means advantageously cooperate in tracts included in the inner periphery of the cylinder means.

Besides the action of the outer ring means, the procedure includes the action of a rekindling 9 means co-acting with the inside of said ring means.

The outer groin of the ring means or the means containing and retaining the ring means can be shaped differently around its circumference.

The ring means and the twisting means are lined with a material having the desired coefficient of friction at-to the yarn.

The material advantageously has a relatively low or very low coefficient of friction 1- relative to itself.

Both the ring means and the twisting means have a particular design obtained on them, at least on their surface and have a possible shallow depression t- so as to enhance the effect of their action. be able to.

Then, the method
Mutual coupling of the untwisted yarns as described above by setting the yarns sideways and moving them to one side and the other side of the center relative to the +r6 center. We may optionally provide means capable of acting on the yarn to cause
Including in joint operation with Jing means.

The method then advantageously includes means for locking the core applied negative twist during intermediate phases of the above procedure during which the applied negative twist may be at least partially lost?
Be specific.

The ring means and the twisting means are brought into close proximity to each other and are included in such a way that they can interact with each other with a desired pressure that can be varied on a time basis according to requirements that can be predetermined.

The pressure acting on the twisting means and the retwisting means can be set and advantageously set.

According to the invention, the untwisting action can be applied for a more or less short period of time to obtain the desired degree of negative twist in the yarn.

As mentioned earlier, the untwisting rudder can be made to obtain a negative twist value of about zero (the fibers would in this case be substantially parallel at the end of the twist), but the initial It is possible to obtain an untwist value of at least approximately a negative twist (as opposed to a positive starting twist) equal to or approximately equal to a positive twist value or an intermediate value of .

The adjustment of the untwisting effect is carried out by one means for adjusting the total untwisting or negative twisting.

According to the invention, the adjustment is capable of retaining the same effect even during the reburn phase (reorganization of the initial twist) and can have a greater or lesser effect or a constant or adjustable or variable effect. ? As you can see, it can vary as desired.

According to the present invention, plucking? ) (plxekinga
pGrt) and the tearing action is carried out by plucking and tearing means which can consist of a Gritz 9-1 paddle-1 suction intake or means cooperating therewith.

During the plucking and tearing phases, the mutual positions (also with respect to the shape of their phases) existing between the yarn, the linder means and the rerubbing means, whether mutually coincident or not, cause the yarn to have a mutual position. Or should the yarn Vc's be placed in such a position that the untorn tract 'kd' of the yarn is emitted? The position is such that two gradually decreasing tail ends or intermediate values occur.

The device has a lever or a means for extracting and expelling the spliced yarn, if the means is not included in the equipment in use to which the device is attached and if the splicer device is used as part of normal use. It can be coupled if it is not on the same axis as the yarn processing during the phase.

In accordance with the present invention, the resulting device can be made to cooperate with an electronic slab catcher, in which case the device is located substantially below the slab catcher (tVc). Dew.

A mutually side-by-side positioning or a mutually in-line positioning can be envisaged.

If the device of the invention is an electronic slab catcher of the ordinary type used to control yarn (and thus not the specific type used to control knots)
The resulting sedge rice that can be applied to the yarn is immediately effectively controlled if it is possible to co-operate with the IC (IC).

According to the invention, a lever suitable for controlling the swinging of the yarn can cooperate with the splicer device and the slab catcher and can completely prevent the swing of the yarn in the slab catcher. possible, thus preventing bad intervention of the slab catcher.

According to the invention, the reburning means are flat reburning means or one single center or staggered along the diameter.
ggered) from specially designed and specified reburning means with two central acoustic sectors or eccentric disks or double helices or combinations thereof.
Yes.

One reburner stage can co-operate with others of the same specification or with others having different specification, which can lie at least partially flat.

The specialized reburning means comprises a suitable cylinder constituting a processing means capable of acting on the yarn.

For example, in a processing means included in a reburning arm having a double helix, after rotation of the reburning means through a predetermined angle, a part of the tar 7 previously rc@ by the processing means is freed and between the processing means It has a width of W that allows it to be worn. This liberalization can be carried out in stages or gradually.

The action of the processing means is applied along the axis of the yarn on itself by a substantially longitudinal action coming uniformly and progressively from the middle of the ring, i.e. from the substantial center of the joint towards its outer edge. This allows for a continuous gradual re-rolling action that takes place gradually.

The pressure exerted on the yarn by the nuclear rekindling means causes mechanical concentration of the fibers and the formation of yarn fuzz (hαC de1n).
eaa) to fuse with the fibers and thus provide inter alia better bonding properties.

Plain rekindling means may be included in place of or in conjunction with the specialized rekindling means as described above.

According to the invention, in possible combinations of said reburning means:
It is contemplated that said means Fi may be paired to include flat or partially flat retwisting means in cooperation with the unwinding/rerolling action of one.

According to the invention, the method of one linder means and one reburning means acting on -1i411 can be the same or different in the dimensions of the other ring means and the other reburning means acting on a@.

It is possible to envisage suitable auxiliary co-operative means for stabilizing the joined tracts, in which case said means can be provided in various ways, for example by microwave, electrolytic or fi-ferment. Electric charge, heated or radiant grates, electric discharge heating effect. Hand II used to generate the desired heating effect! is not appropriate regarding the contiguity of the present invention.

Depending on the yarn, the heated Fi-wire fibers, which can be heated in the range 60°C to 13G/150°C, ensure that the tension in the body of the sedge rice is relieved and their mutual position is fixed. possible.

As mentioned above, the rekindling means can be specified in any number of ways and can be equipped with the necessary auxiliary elements to perform the functions required by the method described above.

Thus, one reburning means may consist, for example, of a suitable modification of the processing means or the like, or of intermediate clamping means consisting of a material which at least partially deflects in a similar manner due to the pressure exerted between the reburning means itself. It can also be equipped.

According to the variant, the intermediate clanbinda means are from the linda in the outer ring means! 75! and is axially movable relative to the outer ring and the reburning means.

The auxiliary common means can also be included in the rekindling means.

Furthermore, the processing means of the reburning means can be of different types and of different shapes and dimensions and can therefore be specified differently.

The processing means of the reburning means advantageously have a VC of a considerable amount on the yarn itself so as to avoid undesired slipping or displacement when one means is sliding and pressed against the other. However, it is advantageous to be made of a material suitable for imparting a low mutual friction II.

For example, the effect of mutual suppression between the ring means or between the reburning means or of the retardation of said means is in any case provided in such a way that the intermediate clamping means are provided in succession or in cooperation with the processing means of the reburning means. When the possible larger height t of the intermediate clamping means is an effect that is overcome by the resulting discontinuous elasticity.

The dimensions and characteristics of the ring means and reburning means can be varied to suit the characteristics of the fibers comprising the tar 7 to be sliced.

In accordance with the invention, the intermediate crank/pi/da means may be movable independently of the rest of the reburning means, and may be operated, for example, by an auxiliary lever or lever means, as described above. It can consist of a pin, or it can consist of a different elastic tension or other means that can be used for that purpose.

According to the invention, the mutual motions between the cylinder means and between the ring means and the reburn means can be the same (i.e. have the same angular velocity if they are circular) or different. can be or can be distinguished.

In the same way, according to the invention, the speed f of the cylinder means and the reburning means can be constant or different phase pulsation speeds f can be envisaged, which makes it possible for the method to be achieved. is within the spirit of the invention.

The invention therefore provides a method for mechanically splicing textile tiles 7, which comprises first untwisting two yarns, which are arranged crosswise, threaded or parallel to each other, audibly and optically;
The two ring means are then mutually retwisted by means of two rinder means or mechanical equivalents thereof acting on the yarns facing each other and located between the two rings. - remove the tail ends of and untwist the yarns in mutually non-interfering positions, then bring them together together at 1 where they are pressed substantially against the phase ff1K and the core In co-operation with the cylinder means, the desired chi 9- of each remaining tail end is

As shown in FIG. 8, substantially ring means 39-40
only operates during the untwisting phase.

At the end of the untwisting phase the stud 43 pulls the yarn.
The untwisted yarns are joined together at an intermediate time, thus allowing the bond to be crunged (51) and plucked or torn and supplemented and sequentially made.

During the plucking and tearing phase, containers 133-134i1
Although combined, the outlets 141 and 234 each allow the yarn to be flanged only in the tract against the intermediate clamping means 51.

The means 53 of flanging the twist to the lever is Yong! ':.

134 (see Figure 8b).
By pressing the ring means 3
that the negative twist of the yarn in the tract between the circumference of 9-40 and the intermediate clamping means 51 is lost by spreading along the yarn outside the ring means and that the positive twist present on the outside Prevent being removed by existence.

Clamping by the means 51 begins at a location of greater thickness at approximately the edge of the intermediate clamping means 51 and tapers to a zero point approximately at the outside of the container 133-134 at the tail end of the paper. It has the effect that it has.

Ring means 39-40 and respective red twist means 41-4
The two riPJTs work together during the plying phase to meet the desired rekindle value.

As mentioned above, the shape and size of the ring or ring means 39-40 and the rekindling disk means or anion means 41-4
The shape and dimensions of 2 and the specific form will vary to suit the average properties of the fibers comprised of Tar 735-36 to be riced.

Obtaining differentiated speeds of rotation between one grate means and another grate means or between a ring means and a plying means is within the yoke of cross-pushing and capabilities of the present invention.

Reciprocal velocity (raaiprocaa apggda) throughout the entire phase or in each phase or pulsation
