Example 1. Electrical wires 1 (Fig. 1) are arranged in a row and, if necessary, are wound synchronously from one coil to another (not shown) with positioning when rewinding to the positions of performing insulation trimming 2 to conductive wires 3 along the perimeter (Figs. 1 and 2) of making the cassette 4 and cutting the wiring wire into jumpers (Figs. 3 and 4).

The operation of cutting the insulation along the perimeter to the conductive veins is performed by clamping a portion 5 of the electrical installation wire 1 according to arrow 6 between

;; by the planes of parts 7 and 8, reciprocating by moving parts 7 and 8 relative to each other along arrow 9, rotating the wire to twist around the longitudinal axes along

10 to arrows 10, rolling along parallel cutting edges 11, which in this case are performed. an annular undercut of insulation 2 along the perimeter at the same time on all wires of the 15th row along lines 12 and 13 at a distance of 1 from each other.

After synchronous movement of the sections 5 to the next position, the manufacture of the cassette 4 is performed.

20 (FIG. 3), by pressing a hardening material in the forming cavity 15 of two parts 17 and 18 that move oppositely along the arrows 16. At the same time, the sections 5 between the lines of the circular sub25 insulation 03 are automatically fixed in the cassette by reinforcement into the material and there is no need laying electrical wiring in the cassette. Collected in this way in a single

30 whole cassettes 4 wiring wires 1 in the row are fed to the subsequent milling position in the cassette of the technological groove 19, which separates the wires into separate jumpers ... j. ki 20 (Fig. 4).

The schematic diagram of the organization of operations allows you to simply change the time of synchronous rewinding of an electrical wire to control the length of the jumpers formed between two adjacent cassettes and continue the method by repeating the described operations several times to match the required length range and the number of jumpers for installation to the number of cassettes produced.

The final operation of the method consists in storing the manufactured cassettes 4 without disturbing their sequence according to the combination of the sections 5 insulated in them of the insulation 2 of the jumpers 20 of the electrical installation wire 55, i.e. assembling the cassettes into block-packs with the adjacent arrangement of the cassettes with the beginning and the end of jumpers of one row (Fig. 6 and 7).

in order to eliminate the entanglement of the jumpers in the block package between the cassettes, parts 21 are installed with a length of 22, equal to half the length of the jumpers in a row.

The block package (Fig. 6) with cassettes 4 and rows of jumpers 20 of various lengths with visually observable inscriptions, for example, on parts 21 provides long-term storage with protection of conductive surfaces. The core is oxidized to be electrically connected to the contacts and convenient to be dispensed jumpers, if necessary, for installation (Fig. 5).

The issuing operation is carried out already at the stage of performing the electrical interconnection of the radioelements when mounting the electronic product and consists in finding the address of the location of the desired jumper length in the block package by visual reading of the engraving on the details 21, grabbing the jumper and applying force twisting along arrow 23.

Example 2. The method is implemented by winding an electrical wire with 1 turn to a coil on a mandrel 24 (Fig. 8-15), cutting the insulation around the perimeter by synchronous firing along lines .25-28 with a torch 29 (Fig. 9 and 10) by forming turns of the electrical wire. in the grooves 30 of the mandrel and forming the cassette 4 under the shape of the groove of the mandrel by pouring hardening material (Fig. 12), dividing the turns of the wiring wire into the jumpers 20 by milling the groove 31 in the cassette 4 on the mandrel 24 (Fig. 13), by inserting the cassettes with jumpers from the mandrel and assembly into block-packs of storing and dispensing jumpers for mounting as in Example 1 (Fig. 11).

In contrast to the implementation of the method of example 1, the principal scheme is op266994

the execution of operations involves ensuring that the required range of lengths and the number of jumpers for installation are consistent with

5 sets of individual, under a certain length, unregulated (Fig. 8), adjustable (Fig. 9, 14) or individually under the program of mandrels 24 (Fig. 15, 16).

10 Example 3. The method is carried out analogously to example 2, but with a modification of the winding of the wire on a flat mandrel (not shown) and the fabrication of a cartridge reinforced with electrical wiring with a pre-processed and folded wire in a loop 32 by gluing two sheet linings 33 and 34 (Fig. 17 , 18) with the subsequent separation of electrical installation wire 20 into jumpers by cutting loops, for example, with scissors (not shown).
