Description

The present invention relates to a portable auxiliary device of

  fitting for the manual sending of the threads of a vertical row considered of coils of one. center in the entredents, associated with this row, the comb of a warper, consisting of a support which, receiving the son of the individual coils in notches, can be transported

to the warper.

  During warping, the re-entry into the war

  In the evening, the wires of the coils nested on the center

  time and requires very skilled and precise work,

  because each wire must be sent individually in the

  associated tooth of the warping comb. In this case, when two wires are erroneously skewed into a comb, or when an entry is skipped, it is usually necessary to

  remedy this error, repeat at least part of the

  ration, which leads to further losses of

  time and increase the idle time of the installation in question.

  As a result, a range of measures have been proposed to provide the operator with

  which, on the one hand, reduce the number of aisles and

  necessary to comb the creel and, on the other hand,

  read an orderly correct tuck into the warping comb.

  The patent application DE-OS-1,535,181 and the document DE-PS-

  For example, 1,710,173 have proposed devices in

  which, to reduce the time of tucking, the row threads

  of a center may be at least aligned and

  in one or more supports that can be transported together to the warper, and by which they are then engaged one after the other in the warping combs. The wire support then consists of a device having a notched edge. In the slots separating the teeth of this support, the son of a vertical row of coils can then be stuck, if necessary glued on the creel, in the successive order in which they must be engaged in the comb. As a result, twisting of the yarns is avoided when these yarns are then pulled on the path from the center to the comb. Then, near the warbler,

  the wire support is brought to the top of the comb and lowered, so that the ordered yarns on this support slide

  in a correct order in the intercepts of said comb, when

  that their distribution on the support corresponds to that of this comb.

  In this known device, to enable the commitment

  As safe as possible by the operator of the threads in the individual notches of the support, it is convenient to maintain a relatively large distance from notch to notch. The wire support is therefore difficult to handle and that is why, in the documents mentioned first, but also in the patent application DE-OS-1 535 181, it has been proposed an improvement according to which a means transporting the wire support (s), movable along the creel to the warper, is conveniently mounted on rolling wheels

  on rails. It is clear that, particularly when the

  tition of the wires on the support corresponds to that of the comb, the engagement of these wires in the notches of a support of the type

  known is extremely painful and subject to many errors.

  In addition, it is not possible to transport to the comb the

  son housed in the notches (without these wires being disengaged

  shallow entredents) that when all

  the wires are firmly held on the creel by brakes.

  However, even when all threads are trans-

  carried in order by means of the support towards the comb, of new

  difficulties arise when the distribution of these son on the support does not match that which is provided on the comb. This is always the case when the support is designed

  so that the wires are easily engaged near the can-

  which requires the presence of the largest possible entredents. In this case, to send the yarns into the warping comb, the operator must try to match the distribution of the yarns imposed by the support with that of the comb, by maintaining said support inclined and / or by varying the distance which separates it from said comb, which requires great skill unless said operator prefers to release the son one after the other of their support and introduce them

in the comb.

  The utility model OE-Gm-7 726 618 describes a

  auxiliary retractor device for overcoming

  ficulty resulting from a faulty coincidence between the distributions of the yarns on the support and on the comb, respectively. For this purpose, a comb-shaped element is used, the ends of the teeth of which are more distant from one another.

  others the bases of the latter. Compared to

  positive advantages, this known device has the advantage of better retaining the wires that are engaged and that, to allow

  the operations carried out on the creel, we have

  teeth larger than with a wire support whose distribution corresponds to that of the warping comb. To transfer the wires of this support to the comb, the distribution

  of these threads must be modified, by a rotation or

  said support, so that this distribution corresponds to that of the comb. This alone indicates that the operation requires great skill and

a fair look.

  The present invention therefore relates to an auxiliary retractor device of the aforementioned type, designed so that, regardless of where the son are taken on the creel and the distribution of these son considered on the comb, it allows to obtain in all

  an optimal distribution of the wires simplifying the most

  each manual intervention considered, and that this

  can be achieved in the form of a device capable of

  to be held with one hand and having a low weight so that the operator using this device keeps a free hand allowing him to seize

and guide the threads.

  According to the essential characteristics of the

  With the aid of such a device, it is thus possible

This provides a handy auxiliary means which can be handled in a particularly simple manner both the left hand and the right hand, can be held in service as a deck of cards and does not exert any troublesome or tiring action. The manufacture of such a device is simple and inexpensive, to the point that it is easy to keep in stock devices

  equipped with different numbers of blades corresponding to different

  possible characteristics of the installation.

  On the other hand, according to another type of embodiment, it is possible to conform the pivot axis of the blades in a.vis associated with a nut, which allows to separate the

  The invention will now be described more in

  FIGS. 1 to 3 illustrate a typical type of warping installation, comprising a V-shaped creel 1 and a warper 2. Tubes 3 of the reel plate of a frame 4 support coils 5 and, in the illustrated example, the creel 1 supports six respective rows of superimposed coils 5. The wires which, when the installation is in use, are drawn from the coils 5 of the creel 1, are individually guided by a wire breaker secured to a bar 6 associated with each of the Vertical rows of coils of said creel (this bar is not illustrated in Figure 2), then they come freely to a comb 7 of the hemming machine 2, each wire passing through an entrance. or interstice of said comb before being returned by a detour roll 8 (not illustrated

  in FIG. 1) on a beam 9, on which it is

rolled.

  Correct warping requires that the yarns

  In this case, as shown for example in FIGS. 1 and 2, the threads of the reels 5 of each of the vertical rows of the creel are spanned up and down in the comb from front to back for each of the vertical rows of succeeding reels. outwardly from the center of said comb 7, thereby starting with a wire F1 of the upper coil of the first vertical row, then continuing with a

  It follows from the description above that the

  A fast but reliable sending of the yarns in the comb 7 in the desired order, have a decisive influence on the profitability of the installation by reducing downtime. In practice, a reliable and rapid process, which has taken precedence over the others, is characterized by the fact that, as shown in FIG. 3, the operator knots together the wires coming from the coils considered Cen starting with the vertical row. previous), seizes them with one hand and, while pulling these threads behind him, goes to comb 7 for

  to engage a thread in each interstice of this comb,

  through the middle and continuing outward. Because of the distance separating the coils, the result is a fan-shaped web, which allows a good discrimination of the son between the upper wire Fi and the lower wire F4. After having done the jigging of the yarns of a vertical row of bobbins, the operator returns to the creel and proceeds in the same manner with each vertical row, until all the yarns are spanned into the warping comb. The illustrated auxiliary feeding device

  in FIGS. 4 to 7, whereby these operations are considered

  accelerated and can be carried out with a minimum of

  dre risk of error, consists of a portable wire support 10. A handle 11, whose configuration ensures a good grip, supports a pack of blades 12 that can

  siderated, in which the creel 1 supports six coils 5, so in which six son must be returned for each series

  vertical coil, it is necessary to provide seven blades 12.

  The blade in the middle of the pack has a shank 13, by which it is fixed to the handle 11. The pack of blades is held together by a screw 14 and a nut 15, but

  can be deployed while remaining at the chosen spacing. The screw 14

  pours aligned orifices of the blades. It serves as a pivotal axis

  This allows the blades to be deployed and grouped and, moreover, it makes it possible to increase or decrease the number of blades 12, or even to replace them, so as to adapt the wire support to any installation of warping. Naturally, we would obtain a cheaper manufacture if the blades of the package were solidariéses by a rivet, in which case it would then be necessary to use

  different media suitable for different numbers of

  no longer possible to change the number of riveted blades.

  The individual blades 12 of the illustrated support.

  are pierced with curvilinear buttonholes 16 which limit the deployment

  said blades 12 cooperating with abutment surfaces not shown. In addition, beyond the free end of each blade 12 protrudes a rod 17 which, in the manner described below, facilitates the seizure of the son of the creel and their

laying on the warping comb.

  The auxiliary retractor device.

  before operates as follows: the operator deemed right-handed and standing in front of the creel (Figure 3) grasps with his left hand, in the usual way the son of a vertical row of bobbins of the creel 1, these son is gathering in his hand in the shape of a fan. In his right hand, the operator holds the support 10 by his handle 11 and, without having to use his other hand, he unfolds the blades 12 to the position shown in Figure 6. The spacing

  T yarns in this deployed position, determined by the

  17, is such that the operator can easily and surely introduce the support 10 into the deployed web, so that

  that a respective thread F slides in the correct order in each

  that interstice separating the rods 17.

  Then, the operator tightens the blade pack 12 and rotates it to the position of Figs. 4 and 5, resulting in a reduction of the gap T (Fig. 6), which becomes t (Fig. 5). The spacing of the son then allows the operator to carry to the comb 7 the whole of the ply engaged in the support lU and from a vertical row of bobbins of the creel, then to send the son in said comb 7 of the manner described above and illustrated in Figure 7. As a rule, said comb consists of a comb "zig-zag", which allows to change, depending on the

  desired density of yarns (number of yarns per cm), spacing-

z that it determines.

  In the illustration of Figure 7, it will be assumed that the six son of a first vertical row 18 of bobbins of the creel 1 (Figure 2) have already been engaged in the comb 7 in which case the upper wire F1 of this first row of coils was introduced at the center of said comb, while the lower row F2 of the first row, which is shifted towards the

  left, is the last thread of this first layer.

  Then the operator moves in the direction of one.

  arrow 19, from the creel 1, with the son of a second vertical row 20 of coils (FIG. 2) ordered in the g

  support 10, then this operator moves said support 10 to

  above the comb 7, so that the first thread of a web 21 is directly placed in the first free interstice of the comb 7 next to the last thread of the tablecloth 19 lastly shifted, as illustrated in FIG. Once this wire is thus oriented, the entire ply 21 of the second vertical row 20 of coils can be lowered and introduced into the corresponding interstices of said comb 7. In this case, the lower thread of the second row of coils again occupies the most extreme position and, during the next work phase, the upper thread of the third row of reels is placed next to this thread. It is therefore obvious that, in this way, the threads of a web can be engaged in the warping comb in a fast, rational and error-free manner. The operator must only make sure that the distance t
