The auxiliary film supply step (S150) is installed on one side of the reinforcing film supply unit 15, that is, the upper surface prevents the flat conductor wire 24 from being peeled from the lower film 11 and harmless to the environment (P) The lower film 11 is attached to the reinforcement film 16 on the bottom from the auxiliary film supply unit 20 which drives the auxiliary film 19 coated with the adhesive for flame retardant auxiliary film under the control of the controller. Supplying in the longitudinal direction on the upper surface of the.

Here, the phosphorus (P) -based flame retardant auxiliary film welding adhesive is harmless to the environment, but the phosphorus (P) -based flame retardant and the adhesive is mixed in a ratio of 3: 7-7: 3 so as to have an adhesive force with the flat conductor wire 24. It is composed.

The auxiliary film attaching step (S160), when the auxiliary film 19 is supplied in the longitudinal direction to the upper surface of the lower film 11 by the step (S150), the reinforcing film cutting unit 17 and the control of the controller The auxiliary film 19 is cut to correspond to the width of the lower film 11 through the auxiliary film cutting part 21 and the auxiliary film heating compression part 22 installed and driven on one side of the reinforcement film heating and pressing part 18. In addition, the auxiliary film 19 is attached to the upper surface of the lower film (11).

In this case, the auxiliary film 19 is attached to overlap the bottom portion of the upper film 10, including a hole formed in the upper film 10 when the lower film 11 is bonded to the upper film 10.

In order to manufacture the flexible multi-core cable through the flexible multi-core cable manufacturing method according to the present invention as described above, as shown in the accompanying drawings 1 and 2, first, the apparatus for manufacturing a flexible multi-core cable is driven by the control unit Corresponding to the above, from the upper film winding bobbin 12 and the lower film winding bobbin 13 installed on the left and right sides, phosphorus (P) flame retardant mixed with a phosphorus (P) flame retardant and an adhesive at a ratio of 6: 4 The upper film 10 and the lower film 11 to which the upper and lower adhesives are respectively applied are drawn out (S100 and S110).

When the upper film 10 is withdrawn from the upper film winding bobbin 12 as described above, the upper film 10 is installed on one side of the upper film winding bobbin 12, that is, as shown in FIG. A hole for exposing one surface of the flat conductor wire 24 at regular intervals is formed through the punching unit 14 driven by the control at regular intervals (S120).

On the other hand, when the lower film 11 is pulled out from the lower film winding bobbin 13 as described above, it is installed on one side of the lower film winding bobbin 13, that is, the left side from the reinforcement film supply unit 15 driven by the control of the controller. The reinforcement film 16 coated with the adhesive on the upper surface is supplied to the bottom surface side of the lower film 11 (S130).

When the reinforcement film 16 is supplied to the bottom surface of the lower film 11 as described above, the reinforcement film cutting unit 17 and the reinforcement film heating and crimping unit 18 operate under the control of the control unit, whereby the reinforcement film 16 is operated. ) Is cut to correspond to the width of the lower film 11 and is fixedly attached to the bottom surface of the lower film 11 (S140).

When the lower film 11 having the reinforcement film 16 attached to the bottom surface is transferred as described above, the reinforcement film supply unit 15 is installed on one side of the reinforcement film supply unit 15 and is driven to the upper surface from the auxiliary film supply unit 20 driven by the control of the controller. The auxiliary film 19 coated with the P-based flame retardant auxiliary film adhesive, in which the (P) -based flame retardant and the adhesive are mixed at a ratio of 4: 6, is supplied to the upper surface side of the lower film 11 (S150).

When the auxiliary film 19 is supplied to the upper surface side of the lower film 11, the auxiliary film cutting unit 21 and the auxiliary film heating pressing unit installed on one side of the reinforcing film cutting unit 17 and the reinforcing film heating pressing unit 18 ( 22) is operated by the control of the control unit, and thereby the auxiliary film 19 is cut to correspond to the width of the lower film 11 on the upper surface of the lower film 11 and at the same time heat-compression is fixed and attached (S160).

Holes are formed in the upper film 10 by the punching portion 14 as described above, and the reinforcement film 16 and the auxiliary film 19 are fixedly attached to the bottom and the upper surface of the lower film 11 so that the upper film ( 10) and the lower film 11 is transported, while the flat conductor wires 24 are supplied at equal intervals through the alignment supply unit 25 (S170), between the punching unit 14 and the auxiliary film heating and pressing unit 22 It is installed in the lower portion of the heat-compression through a pair of heat compression roller 26 to be driven by the control of the control unit (S180).

Thereafter, the production is completed by winding each while cutting in the longitudinal direction through the cutting portion having a plurality of blades.

As described above, the flexible multicore cable manufactured by the flexible multicore cable according to the present invention is manufactured by using a phosphorous (P) -based flame retardant adhesive which is harmless to the environment, and thus does not pollute the environment when the flexible multicore cable is disposed.

In addition, even when using a phosphorous (P) -based flame-retardant adhesive that is less adhesive than bromine-based flame-retardant adhesives, it is possible to prevent the conductor portion exposed by the auxiliary film from peeling off from the lower film, thereby significantly reducing the defect rate due to the manufacture of a flexible multi-core cable.
