Description

Detailed Description of the Invention (Industrial Application Field) The present invention is mainly directed to a manufacturing device for a laminate-type undercarpet tape-like electric roll, in particular, a manufacturing device for manufacturing a tape-like electric roll for a laminate type undercarpet. The present invention relates to an apparatus for producing a tape-shaped electric wire by crimping and bonding the tape-shaped electric wire between both rolls.

(Prior Art and its Problems) As an apparatus for crimping and forming a tape-shaped electric wire using a pair of crimping rolls, it is preferable to use a device in which a metal roll and a heat-resistant rubber roll are arranged facing each other as described above.

In other words, from the electrical characteristics point of view, the problem when crimp-molding wires in a laminate type tape shape is the adhesiveness of both ends E of each core wire group (sheath core) 1' in FIG. If, for example, a crimping device for metal rolls is used, the adhesion between both ends E of the core wire group 1' shown in FIG. 7 will be incomplete, and a gap will be formed at the end E. In addition, in a crimping device for rubber rolls, a large circumferential speed difference occurs between the rubber roll portion corresponding to the core wire storage convex portion 7 and the bonding portion 8, wrinkles occur in the appearance, and sufficient manufacturing conditions cannot be obtained.

Furthermore, it is difficult to keep the rubber roll in a high temperature state for a long period of time.

For the reasons mentioned above, it is preferable to use a combination of a metal roll and a rubber roll.

However, even when a metal roll and a rubber roll are combined, conventional crimping equipment has a flat surface for both rolls, and is often equipped with only one set of rolls. The following problems may occur.

That is, since the tape is crimped between flat rolls when supplying the tape, it is not possible to absorb the deformation of the tape that occurs when the uneven parts such as the core wire storage convex part 7 shown in Fig. 7 are clamped. , there still remains a problem with the adhesion of the core wire group end E. This does not pose a particular problem when the pitch between the wire groups, that is, the width of the adhesive 18 between the laminated tapes, is larger than the core wire group 1'. When the distance is less than 3 m+, the adhesiveness is extremely deteriorated. As a result, the relationship between the conductors becomes unstable, causing problems in terms of electrical properties (mainly capacitive coupling).
Telephone wires can also cause crosstalk.

It also provides support for perforation processing and terminal construction after pressure bonding. Furthermore, the phenomenon of breakage of the aluminum layer A shown in FIG. 6 may also be a cause.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a plurality of crimping roll sets including a metal roll and a rubber roll in order from the tape-shaped electric wire supply source side, and a plurality of crimping roll sets including metal rolls and rubber rolls are provided in order from the tape-shaped electric wire supply source side, and the crimping roll sets between adjacent crimping roll sets are , the positional relationship of the metal 1 coil and the rubber roll with respect to both sides of the tape-shaped electric wire is arranged in reverse to each other, and one roll of the crimping roll set closest to the tape-shaped electric wire supply source is

Each core wire storage convex portion 7 contains five core wires C. For such a tape-shaped electric wire (1), a wide annular groove corresponding to the width of the convex portion 7 of the electric wire shown in FIG. 10 is formed, for example, as the groove of the metal roll of the first crimping 10-ru set. Further, the width of the projection 91 of the presser foot 26 is also formed to match the annular groove.

(4) Is it tape-like with an almost flat top surface as shown in Figure 9?
l! The present invention can also be applied to wire manufacturing.

(Effects of the Invention) As described above, the present invention includes a plurality of crimping roll sets 11.12 each consisting of a metal roll and a rubber roll in order from the tape-shaped electric wire supply source side, and between adjacent crimping roll sets 11.12. , Gold jil o-ru 2 on both sides of the tape down type line.
The rubber rolls 7.43 and 28.42 are configured so that the positional relationship is opposite to each other, and a plurality of core wires are guided to one of the rollers of the crimping rollers 11 closest to the tape-like electric wire supply source. Since the annular groove 40 is provided and the preform presser roll 26 is provided having a plurality of annular protrusions 91 that engage with the annular groove 40, there are the following advantages.

(1) Crimp 0 composed of a gold roll and a rubber roll
- In addition to providing multiple roll sets, each pressure roll set 11.1
2 rubber roll 28.42 into tape form 1! Since they are arranged alternately when viewed from the wire side, it is possible to completely bond both sides of the wire, and the circumferential speed of the roll can be kept constant, without wrinkles in the appearance. It is also possible to maintain high temperatures over time, further improving adhesive performance.

(2) Before the crimping process, between the crimping roll 27 having a plurality of annular grooves 40 and the preform pressing roll 26 having a plurality of annular protrusions 91, the laminate tape 5' is attached to the core wire group 1'. Since the tape is preformed into an uneven shape that follows the shape of the tape, unreasonable deformation and distortion of the tape during crimping can be eliminated, and both ends of the core wire group 1' can be reliably bonded. Therefore, it is possible to provide a tape-shaped electric wire of good quality. Moreover, phenomena such as breakage of the aluminum layer of the tape T can be prevented.

(3) By completely adhering both ends of the core wire group 1', the conductors are stabilized, and it is possible to prevent 1ld12 of the telephone line due to electrostatic coupling or the like.
