NO800152L - AUTOMATIC MACHINE FOR MANUFACTURING SEGMENTS OF ELECTRIC conductors - Google Patents

Description

The present invention relates to a machine for

in a completely automatic way to produce a series of segments of jwires or electric conductors which are identical and different between themselves, in particular starting from a series of electric coils of wire, and to encapsulate in at least one box one one or two ends of each of these manufactured segments. j

Machines are known which automatically perform certain operations for the production of segments of wires or conductors and encapsulation machines where usually manual operations are necessary between several of these machines to perform all-manufacturing joints and the encapsulation. Furthermore, these machines can usually only perform certain operations on the electrical conductors or segments of such conductors which are mutually identical.

The machine according to the invention, on the other hand, makes it possible to carry out automatically and with great reliability all these operations with segments of conductors which can be different or the same with regard to type and length and makes it possible to reduce costs and increase the possibilities.

The invention thus relates to an automatic machine for the production of a series of segments of wires or electrical conductors and for encapsulating at least one end of each of these produced elements in at least one box, characterized in that it comprises in combination a number of workstations for producing from reels of electrical conductors or segments of electrical conductors which may be equal or different in terms of length and/or cross-section, a series of segments manufactured as required, of different electrical conductors and to encapsulate, at least one end of each of these manufactured elements in at least one box, devices for control to transfer orders to each of the mentioned items to produce each of the individual operations that they comprise and control devices to only, among the mentioned control devices, make effective those necessary for the elementary operations to be carried out on the items

In i

to efficiently process the segments of electrical conductors in a predetermined series at the moment when at least one conductor is on a post, in which said control devices jfurthermore determine the degree of'elementary operations which present different degrees according to the series of segments! during treatment.

These items may include all or a certain number of the following items:

a) on one side:

- post for disengaging wire or conductors from reels,

- post for checking the integrity of the conductors, this post shows thickening or a lack of insulating material,

- mail for correcting the threads or conductors,

mail for briemsing of these,

- post for the control of the entrance for these,

- post for marking these threads or conductors,

- post to select threads or conductors,

- post for cutting these into segments,

- post to modify the length of certain segments of wires or conductors,

- post for cutting in the middle of segments of conductors; and

b) on. on the other hand, posts that will process segments of wires or conductors of the same length or different lengths and in particular one or the other end of these segments: - posts for removing insulation on one or both ends of the segments of conductors, - posts for removal of insulation from the segments from an area other than the ends,

- control posts for insulation removal,

- posts for putting on end sleeves on one end of the segments of conductors, - posts for putting on contact elements on one or both ends of the conductor elements, - posts for putting on contact elements for connecting or welding wires, in ■

- items for soldering contact elements,

- posts for tinning the ends of the conductor elements,

- records for recalibration of the pre-drilled ends,

- posts for driving end sleeves,

- items for adjusting end sleeves,

- posts for marking the ends,

- posts for automatic fastening in a box,'

posts for regrouping the strands by means of fittings, ribbons or split rudders or spirals;.

and this list is not limiting and the order of the entries may be different.

Preferably, a machine according to the invention can process two threads at a time.

The jobs that process the leader segments can in certain cases be divided into two subsequent batches that are separated by! a transmission device.

The general synchronization of all movements in the machine according to the invention is carried out by means of impulses which constitute the control orders and which are delivered by a programmable automaton which constitutes the control device, the tempo in this automaton is determined by impulses coming from a time base or horology which makes it possible to provide different tempi according to the operations to be performed on a given series of electrical conductors.

The invention will in any way be better understood with reference to the following description and the attached drawings which are only given as an indication. Fig. 1 schematically shows the system of the machine according to the invention, seen from above. Fig. 2a, 2b and 2c, once assembled according to a-a and b-b, show an example of a matrix called a definition Fig. 3a, 3b and 3c, once assembled according to c-c and d-d, represent an example of a matrix which is called program, the matrices in fig. 2a, 2b, 2c and 3a, 3b and 3c are used to control the machine in fig. 1 to produce

in

in

a specific structure of electrical conductor bundles with one or more boxes.

According to the invention, and more specifically according to

one of the designs, and likewise according to the designs of the various parts that are preferred, one suggests e.g. to produce an automatic machine for producing wires or electrical conductors and encapsulating them in at least one box, and one proceeds as mentioned in the following or on a corresponding mate-.

In fig. 1 shows that the machine includes a certain number of work stations where the order is not critical, which act first on the electrical conductors, then on the segments, the length of which (possibly this may be different) is fixed, such as conductors and finally on these segments and 'boxes, and the machine is fed on one side by conductors from coils A held by a winding device B, and on the other side, by boxes by means of distribution devices C-^ and C^, e.g. of vibrating distributors.

One can process series comprising a large number of conductors;, e.g. up to 30 conductors, where the cross-section, type and color are the same and/or different, by dividing these into segments of equal and/or different length and connecting one end or both ends of these segments, single or multiple, in one or, several boxes in one or more rows of holes or in holes placed in some predetermined distribution.

The first record in the machine according to a. preferred embodiment according to the invention - after the spool holder B which feeds the rest of the machine from spools A (where eight are shown) of wire or electrical conductors which may be the same or different and which stand in the correct sequence in these spools - is a control post D for the integrity of the managers.

This control post D has the purpose of confirming that the wires or conductors to be processed by the machine do not have excessive thickness (especially ends), or local absence of insulating material (in addition to bare ends

in I

In i

to signal a .dielectric fault) which can break down the parts of the machine which are placed in front of this post D.

When an electrical conductor has one of these faults,

will the control post D command the stop of the machine and share this leader; to remove the part that is in bad condition. The internal device can be of a mechanical type, optical or pneumatic for example.-.

The device D can also have a roller which is placed on an articulated arm and which rests on the wire and displacement ajv this roller measures thicknesses or sub-in

thicknesses of the conductor; in these two cases, displacement of the roller past a certain position will cause a micro contact to close which can produce a reaction from a knife cutting across the wire.

The control post D is followed by a post for straightening the conductors or threads, this post is of a known type and comprises rollers which are placed one behind the other, but which work perpendicularly to each other. This record E can e.g. include two systems of five rolls for each of the leaders.

Then comes a brake post F for the leaders. In this post, each of them can, for example, go through two cities that serve as fixed control and where between them is located. a plate equipped with a brake foot. The post includes movable plates that are mounted on articulated shafts that can rotate and are equipped at the ends with a friction body that should rub against the wire or conductor. You can usually have several increasing clamping forces of the soft plates against the wires so that the desired braking is obtained. This braking is necessary, on the one hand, to reduce the inertia of the threads and, on the other hand, to ensure that the threads are well stretched (but not too stretched) for the stretching of the sheath post, which will be studied in the following.

Behind the brake post F is a post for input control G which must regroup and guide into a minimal volume the conductors or wires that are to reach the cut post.

The device can also include a marking post H which provides for a marking of the conductors, e.g.

a hot marker ring with a suitable band.. In the illustrated version, it has been assumed that the marking post only marks a single thread or conductor at the bundle, but you can of course have a design that marks several threads. You can also let... this device work on wire pairs.

At I, a record has been schematically shown which sor-

provides for the selection of threads or conductors. This record is e.g. of lawn type as described in the French patent application filed by the patent applicant on 28 September 1978 under national

in

national registration number 78 27855 with the title "Dispositif pour alimenter un poste de travail avec une série d'articles, notamente de jf ils électriques, dans un ordre prédéterminé"... and preferably of the type described in the requirement of the first addition to the said application 78 27855,

where the supplement was delivered on 18 January 1979 with the number 79 01287.

According to this reference, the device for feeding a work station with a series of articles, and in particular leaders or pairs of leaders in a predetermined sequence, is characterized by the fact that it comprises - together with n distributors of articles and a work post which is to receive a series of articles comprising up to n articles, and in particular n conductors or n pairs of conductors which between them come in a predetermined sequence, in combination n movable article carriers, n shifting devices which can shift each of the n article carriers between a collection. tilling where they can pick up an article from n distributors and a delivery position, the delivery positions are all located in the same restricted zone, control devices for influencing in a predetermined sequence each of the n displacement devices to move the associated article carriers article carriers from the collection position to

IN

a delivery position - and then, after a predetermined time, from a delivery position to a retrieval position and gripping means for picking up the articles successively located in the restricted zone and delivering them to the work station. According to the addendum, the displacement devices occupy a waiting position for their delivery position and the restricted zone consists of the common delivery position for all displacement devices.

This arrangement makes it possible to supply a large number of electrical wires g or pairs of electrical wires which may be the same or different, in a predetermined sequence to the final work stations.

Behind| in the selection item I there is a cover item J which includes cover devices, e.g. a pneumatically operated knife, and these devices cut only one thread or a pair of threads at a time, namely those just dealt with in item I for selection of threads.

Next comes post K which will vary the length of the segments: of wires or conductors.

In order to be able to give the threads or conductors different lengths, this item has been inserted which will lengthen certain of the threads and this regulation works on the shortest thread in the bundle to be produced; the post that varies the length K makes it possible to get several different lengths. It processes a single thread or a single pair of threads at a time, those or which are "offered" by the thread selector I to a pulling system located at L. The post K works by means of a pulley system, i.e. it buoys a S with greater or lesser length of the thread to be treated in such a way that it is lengthened more or less. The placement on the hoist takes place by bringing forward one or two guided carriages each with a roller, the degree of bending and thus extension of the thread is produced by varying the course of the carriage; to manage this course you use e.g. a pneumatic jack that acts on a lbper. This lbper can move in a drum with several bars

In i

in , .

to which you can attach a screw that acts as a stop cam for the runner so that you can regulate the extension.

Man| finally obtains segments of wires or conductors which are placed in a predetermined sequence, and these segments h can be checked for uniformity whether they are the same or different, by species, cross-section, color and finally by length (due to of the mail

K variation in length). These segments of conductors are taken up on a conveyor belt M which guides them in the direction of the arrow F and . allows them to page over a series of records positioned vertically and to the left of the conveyor belt; and these records have index 1 when they are to the left of and index 2 when they are to the right of the conveyor belt M. The Trånspor band actually consists of two conveyor belts. M-^ and IYL,, one to the left and the other to the right. There are preferably a number of items along the conveyor belt.

First, two posts N-^ and N 2 to remove insulation from one of the ends of the segments of the conductors h; these posts are equipped with a machine that can remove the insulation from the ends of the wires; one assumes the possibility of removing insulation from conductors or wires with different cross-sections using e.g. a pneumatic jack with different coaxial steps which determines the approach amplitude of the blades which carry out the removal of the insulation as a function of the cross-section of the wire in question.

The control of the removal of the insulation, i.e. the control of whether the insulation removal has been effectively carried out on the posts N-^ and N 2 is carried out in the posts P-^ and P2. This control is carried out using e.g. fblers which control the passage of an electric current through which the insulation shall be removed; if this removal is not carried out correctly in the posts N-^ and the measuring posts P-^ and ?2 will produce automatic removal of a wire whose end (according to the program) has not had the insulation removed in a correct way.

One can likewise produce posts for removing insulation from segments of conductors in an intermediate zone, cutting posts for the middle of the segments and certain or all of the other posts mentioned in the introduction.

You then have the records Q-^ and Q2 for automatic insertion! of end sleeves (insulating compressible sleeves). These two items must automatically apply end sleeves on the ends of the threads that will receive this. Each post is fed by a long length cover which is cut to the desired length to produce an end sleeve. The device for cutting up is optionally terminated with a device for shrinking and a positioning device, and the first

in

has the purpose of producing a limited deformation of

in

the sleeve by thermal shock to give it the necessary geometry to place it on the end of the wire, while the other device aims to place the sleeve on the crimped connection.

The folding post R^, R2 consists of presses that can receive special tools as a function of the connections to be folded.

One can also have records for tinning which make it possible to line certain ends or certain central parts of the conductors (which are determined in the program) under a stream of molten tin after a previous application of a suitable flux.

Subsequent posts for shrinking the sleeve have the purpose of attaching the sleeve to the folded connection and the shrinking effect is achieved, e.g. by means of hot air produced in a rudder line.

It is clear that the sequence of the various operations is not critical.

It is noted that the drawings have not shown the posts for pre-shrinking, placement, tinning and shrinking which can be placed along the conveyor belts M-^ and M2 or between these conveyor belts.

You can also distribute the subsequent items

'IN

in two series and provide a transmission system between these two series for the leader segments.

The final item along each conveyor belt

is a post fojr automatic fastening of the ends of the electrical . conductors, or wires in a box. These items which receive boxes of the distributors C-^ and C2 and which are represented by S£Ojg S2, preferably consist each as described in French patent application of October 25, 1978 with national registration number 78 30352 entitled "Dispositif pour enficher des Jéxtremités de conducteurs électriques our d'éléments analoguea dans un boltier".

On each post S-^ and S2, in this case, there is a device for guiding the ends of the electrical wires or similar elements into a box, characterized by the fact that the device includes, together with a fixed drainage chute, which brings forth a number of boxes that are oriented in a suitable manner, and a conveyor belt for conductors or wires capable of advancing in a predetermined sequence a number of conductors with at least one end free, with the free end of each conductor in a predetermined position, - on the one since a box holder comprising means for receiving a box from the feed chute and means for guiding this box through a predetermined sequence of fixed, determined positions, in each of these positions a recess or hole which is determined. in the box occupies a fixed position in the room, and devices for releasing the box when the conductors are connected to it, and - on the other hand, a system for supplying and fixing successive wires or conductors which comprises devices for gripping which can grip and release a conductor, devices for placing the gripping devices just opposite a conductor which has been brought into position by the said transport device, devices for controlling the gripping of the said conductor by the said gripping devices, devices for

in

fore them. said gripping devices together with the conductor which they have gripped in a position just opposite the fixed position in the space occupied by the said recess which is predetermined in the box, devices for displacing the said gripping devices and finally for attaching the said free ends of the conductor which are held firmly in the said recess and to secure the fixing of this wire in the hole and devices for releasing the said wire from the said gripping devices when these occupy a predetermined position.

Eighties this description of the mechanical system

in the machine one must describe, as a non-limiting example, devices that make it possible to get an automatic effect from this machine.

This electrical control is carried out from an electronic, programmable automaton of a known type.

You first need to produce a program, preferably on a disk, which gives a schematic representation of the various items in the machine, the necessary information for; to produce the program. One can thus (see fig. 2a, 2b, 2c placed next to each other): a) dope the threads in the relevant bundle with the numbers thread no. 1, thread no. 2...etc. (or pairs of threads No. 1, No. 2, etc.); b) select the order of fastenings in the threads of the box or boxes (a single box on the left or a single box on the right, or a box on the left and a box on the right, for example); c) indicate the specific tool city in relation to the fortress post; d) specify vertical spaces on each box in the case where the box has two rows of holes; e) specify the horizontal space between the holes (for d) and e) and it has been assumed that the box has one

or two rows of holes; in the case where the holes are placed unevenly or where the device for fastening includes

I ■ '■

■ ■ I

rotatable ion devices which in the embodiment mentioned in the aforementioned patent application no. 78 30352 specify the value for displacement in length and direction of rotation);

f) indicate whether variation in length should be used and in this case specify for each of the threads or

the wire pairs divided relate to the addition or additions to the length that must be given in relation to L. the minimal base- . the length where the base length can also be specified, either

BA, BB, BC... BK;

g) indicate the sequence in which the threads are presented to the thread selector of the type shown in the aforementioned

patent application no. 78.27855 and the supplement 79 01287 (remember that in the case from application no. 78 27855 the threads with different numbers - no. 1, no. 3 etc. were placed on the left and the threads with the same number, no. 2, no. 4 etc. to the right and that the last thread with different numbers is in the centre, e.g. AA, AB, AC, AD, AF to the left, AH, AJ, AK, 'AL, AM, AN' to the right and AG in the middle, this is necessary

in the voter according to the supplement);

h) indicate the active items placed under the conveyor belts, namely some or all of those mentioned below

items:

- the programmable insulation removers N-^and N2

and the detectors P-^ and P2 which are placed e.g. in positions 6CG, 7CG, 7CD and 8CD (the letter G corresponds to the left edge and the letter D to the right edge); in certain cases, you can have central items (jacking devices, devices for removing insulation etc); - the other items can be placed in all other positions at 1CD to 20CD and 1CG to 20CG (while of course one must take into account the technical requirements inherent in certain devices and in positions that are already occupied by programmable insulation removers and the detectors for this ); - a position such as that indicated by the shaded zones in fig. 2a, 2b, 2c comprising an outlet for electrical impulses;

i) specify whether to mark a thread.

When one has defined the operations to be carried out in different records for a series of bundles of segments of conductors or wires, a matrix called a definition is produced which includes for each line the number of wires in the bundle and in each column for each of the two conveyor belts! the different functions to be performed on each of the threads in the bundle. Such a matrix is shown in fig. 2a, 2b, |2c, placed edge-to-edge, and joined

j

along aa and bjb.

One can now examine a special example of

a bundle consisting of five wires or conductors with fastening in a single box located on the edge of the trans-

IN

the gate belt to the left M-^and with three end sleeves in the conveyor belt to the right M2:

In this example:

a) the last wire in the bundle is wire no. 5 which serves to automatically reset to 0 the programmable electronic automaton; b) in the case where the wire selector is according to the above-mentioned patent claim no. 78 27855, the five wires are operated in the following order: - wire no. 1 in the first board' on the left (AA),

- board no. 2 in the first board to the right (AH),

- thread no. 3 in the second board to the left (AB),

- thread no. 4 in the second steering wheel to the right (AJ), thread no. 5 which is the last with different numbers in the steering wheel in the middle (AG); this is not necessary in the case where one chooses according to the addendum to the patent application: c) thread no. 4 is marked; d) in the item for variation of the length are two stop cams that can be pushed regulated, namely one stop cam of 100 mm (for threads that are 1,100 mm, namely 100 mm more than thread no. 5 which is the shortest and which is only 1,000 mm) and a stop knot of 200 mm (for the threads which must have a length of 1,200 mm, namely 200 mm more than thread no. 5 of minimum length); and BA and BB are these two stop cams for 100 and 200 mm respectively: - thread no. 1 (1,100 mm) is extended using stop cam BA, - thread no'. 2 (1,100 mm) is extended using stop cam BA, - thread no. 3 (1,200 mm) is extended using stop cam BB, - thread no. 4 (1,200 mm) is extended using stop cam BB, - thread no. 5 ( 1,000 mm) is not extended at all

■ taken since it is the shortest of the five and corresponds to the basic mechanical draw length in the machine;

for the removal of insulation from the ends of the edge facing the conveyor belt M^, it is assumed that the cross-section of the wires is as follows:

- thread no. 1: 0.6^

- thread no. 2: 0.6<2>

- tjråd no..3: 1^

- thread no. 4: 0.6<2>

! 2

- thread No. 5: 1

e) the hiåleposten to demonstrate whether there has been a removal of ice insulation must be active for the fém_ threads on

same side as conveyor belt M-^;

f) cf or removal of insulation of the ends on the same side as the conveyor belt M2, only some items will be

active page:

r- thread No. 1: the insulation has not been removed since

the connection is false,

- wire no. 2: the cross section where the insulation is to be removed 0.6 - wire no. 3: the cross section for the part where the insulation is to be removed 1 - wire no. 4: cross section, for the part where the insulation is to be removed* al is removed 0.6<2> wire no. 5: the insulation is not removed because of the crimped connection g) the measuring post to detect if the insulation is removed on the same side as the conveyor belt M2 is only active for the wires hr. 2, 3 and 4, where the insulation must be removed; h) in position 8CG, for example, there is a folding post for the connections where end sleeves of type x are attached and each of the wires 1-5 can receive such a connection of type x, in contrast to the side where the conveyor belt M2 is located, there can be two folding posts, one located at 9CD for connections of the type y for the application of wire no. 3 and the other in position 12CD for folding a<y>connections of the type z for the wire no. 2 and 4;

i) on the same side as the conveyor belt M2 where there is no box for attachment, in this case the pliers transfer the insertion post located on this side, and which is found in the device for the automatic attachment according to the aforementioned patent application no. 78 30352 which only needs to take the threads after the displacement of the threads at the exit

j

of the conveyor belt M£ and M2 are correct and this gripping takes place last year each of the threads no. 1 - no. 5;

j) |on the opposite side of the conveyor belt M-^in addition to the gripping, placing in a box and in it! example chosen, the box has only one row of holes which can be considered to make up the lower row (in another example with a box with two rows you start with the lower row and end with the upper row), a fastening can take place in each hole in the selected example;.

k) to determine the lateral displacement of the box and the distance to a hole, one must give each thread a displacement direction forward or backward, likewise : the number of steps it must displace; and furthermore, one must specify which number is the last wire to be fixed so that after this, the fixing is reset to zero, and in the special case mentioned: - wire no. 1 is fixed in hole no. 1 with the box holder in position at the rear stop cam (no special indication is given);

- thread no. 2 is attached to hole no. 2, you must then give

one item (as an order) in the column "advancement of the box" and another in column No. 1 "Number of holes to be moved"

(since there is not just one hole's distance in the direction of progress between the first hole and the second);

- thread no. 3 must be fixed in hole no. 4 (this is only used to show the possibilities in the machine), you must therefore enter one point in the column "Advancement of the box" and another in column 2 "Number of holes to be moved" (because there is a distance of 2 holes in the forward direction between the second and fourth holes); - thread no. 4 is fixed in hole no. 3, one must then enter a point in the column "Return of the box" and another in column no. 1 "Number of holes to be shifted" (since there is a distance of one hole in the return direction between the fourth and third holes; - thread No. 5 must be fixed in hole No. 5, one must indicate one point; in the column "Advancement of the box" and_ another in column 2 "Number of holes to be moved" page there is a distance of two holes in the direction of travel between the third and fifth holes; it must also be specified that the fastening must take place for the five threads no. 1 to 5 on the same side as the conveyor belt M--, L.

1 the system in fig. 2a, 2b and 2c have been indicated

by means of ipoints the operations carried out on each of the threads No. lj, No. 2, No. 3, No. 4 and No. 5 in each of the posts (for the posts placed in the zone of the conveyor belts M-^ and M2, the position has been entered on these items). Manj will now explain what is called a matrix

in

which is easily referred to as "program", which can be placed on top of the definition matrix and sbm makes it possible to report the action points without difficulty, when preparing the matrix program on transparent paper..

An example of a matrix program corresponding to the definition matrix in fig. 2a, 2b and 2c are shown in the system of fig. 3a, 3b and 3c which are connected along the lines cc and dd.

In this figure system, 3a, 3b and 3c correspond

the horizontal lines to different conductors or wires. The first five lines have been numbered, which correspond to threads no. 1, no. 2, no. 3, no. 4 and no. 5. On these five lines, the points in the definition matrix in fig. 2a, 2b and 2c, as well as the various records or locations. In fig. 3a, 3b and 3c, the broken lines represent electrical impulses emitted by the electronic automaton during operation, the points which are reproduced in fig. 3a, 3b and 3c correspond to electrical signals which the thread (No. 1, No. 2, No. 3, No. 4 and No. 5) receives during processing on the corresponding record.

If you e.g. viewing thread no. 1 (first

line from above), you can see that at the post which is to vary the length K (at F-j^) you can use the stop cam BA and you must therefore ensure that you get a signal from the automation in order to

j

get an extension to a desired length.

Likewise, for wire no. 1, an electrical impulse can be obtained at the post that removes the insulation N-^ (at F2)

<p>g another impulse at the folding post R2 (at F^) to place a connection of type x on the same side as the conveyor belt M2 and an impulse at the automatic fastening device "S-jj (at F^) with a simple grip on the same side as the conveyor belt M2> You proceed in the same way for threads No. 2, No. 3, No. 4 and No. 5 in the bundle. For each of the items in the program, you examine one after the other of each of the vertical corresponding lines to a post or a location and for each of these points the necessary impulse is set up and marked below the vertical line. The automaton can then send out a series of impulses and the time interval corresponds to the distance between the two vertical lines and is a function of the general' rate of the machine.

When considering fig. 3a, 3b and 3c, one can notice the following: a) the vertical line 1 provides space for a last thread in the bundle (this introduces the number of threads into the program

which is covered by each bundle), in fig. 3a, a point has been marked on line 1 opposite thread no. 5;

b) the vertical lines 26 - 71 (inclusive), and likewise the lines 106 - 107 correspond to records which

stands in relation to threads in motion (posts at the level of the conveyor belts M-^ and M2 and mobile parts in the automatic attachment post);

c) each thread is actually baptized at the moment it is cut and the name it receives - in this case

a number - serves to initiate certain operations, namely those required by the passing of the threads in the various posts in the machine according to the invention;

d) the records in this machine just start to

act at the start of a series of identical knots when a thread

which produces a corresponding operation arrives at the

current post office; it.is not in operation, but "in idle_" when the machine is equipped with threads;

e) |in a similar way at the end of a series, when the machine jstarts processing the last bundle in a

series, the electrical pulses will not create the entire program and only the impulses corresponding to threads that are not. terminated will be produced. This leads to a stopping of the machine according to the invention so that no conductors are lost. The matrix program in the system in fig. 3a, 3b, and

3c is established by transferring the points for the definition matrix (figure system 2a, 2b and 2c) and by indicating the electrical pulses, one introduces these pulses through the control keyboard of the programmable automaton, into the memory of the automaton which includes all information relating to the impulses to be emitted in relative to a bundle in a series. Insertion of the impulses into the memory takes place from vertical line to vertical line (from line 1 - line 107), from left to right.

When the programming of the automaton for a given bundle has been determined, one can start processing a series on this bundle and make a registration that makes it possible to -save the program compared to the final series.

In connection with the programming, only the variables that are linked directly to the particular bundle to be produced in a series have been mentioned, but other information of a general nature is necessary for a normal operation of the machine, (e.g. those that concerns the termination of certain movements, the start and stop of certain brakes and safety micro-contacts).

One can thus see that the invention makes it possible

å. produce an automatic machine which can produce a series of bundles each consisting of segments of electrical conductors which are fixed in at least one box by using a programmable automaton of a known type available on the market, e.g. of the type AP-144 from SILEC, this machine enables a regular production with reduced costs

manufacture knjiip<p>e<r>of different types, the number of segments of wires can1 vary and likewise their nature, length, cross-section and color, furthermore, different types of boxes and connections can be used at the ends of the segments of the electrical conductors.

The invention is not limited to the uses, claims and embodiments described here, but includes all variants.
