That is, a plurality of strand bobbins in the strand feeding part A,
For example, each of bl, b2, b3, and b4 is connected to the twisting device B.
After twisting each of the strands W1, W2, and W3W4 in the same direction, they are collected and sent to the tape winding device T.
The tape is applied by the wire twister B, and the wire is twisted by the wire twisting device B and wound onto the take-up bobbin B1.In this way, when the wire is fed out while being twisted at the stage of feeding, the wire is not twisted. Of course, compared to the case of simple sending, multiple devices are more expensive, high-speed operation is impossible, and power consumption is high.
In addition, large-diameter wire bobbins cannot be used, and they must be replaced frequently, resulting in overall inefficiency, and many other drawbacks. The present invention eliminates these conventional drawbacks, and utilizes a novel intermediate twisting device developed and patented by the applicant, which allows the strands to be fed out without simple twisting. This communication cable manufacturing equipment has a simple configuration that allows for an integrated process in which the wires are untwisted individually in an intermediate process, converted into two, and wound with tape, and has extremely low power consumption and high-speed performance. It provides:

As is clear from the figure, the strand w fed out from the strand feeding wheel is not twisted, but is passed through the dancer roller 15 for tension adjustment by the next intermediate twisting device 2. Each strand is individually twisted. The intermediate twist applying device 2 has a twist roller 23 attached to a hollow shaft 21 rotatably provided on a base and having a number of wires equal to the number of wires, and a twist roller 23 attached so that the bottom of the groove is in contact with the center axis of the shaft. It is rotatable, and furthermore, guide rollers 22 and 24 sufficient to prevent twisting of the strands are arranged upstream or downstream of the twisting rollers, respectively. (In the illustrated example, both are provided.) 27 is a pulley attached to the hollow shaft 21, 28 is an endless transmission belt such as a V belt or a timing belt, and 29 is a drive shaft driven by a variable speed motor 26. The drive pulley 25 is attached to the drive pulley 25, and in order to twist the wire w, the variable speed motor 26 must be operated to have a periodically varying rotation speed. The reason why twisting is imparted to the wire w by doing this will be described later. 3 is a twisting die, and the wires gathered here enter a tape winding device 4.

The tape winding device 4 may be of a known type; briefly, 41 is a tape pad coaxially attached around a hollow shaft 46, from which a tape 43 is drawn out and wrapped around the stranded wire. The stranded wire S is wound around the stranded wire S by a tape hanging arm 42 which is rotationally driven. Note that 45 is a drive shaft that drives the hollow shaft 46;
4 is a transmission. Immediately downstream of the tape winding device 4 is a pre-twisting device 5, which will be described in the next two steps.
It rotates in the same direction as the multi-twist type winding device 6 at a rotation speed approximately twice that of the twisting type winding device 6, and twists the wires gathered together by the twisting die 3 as a twisted wire S. In this device, 51 is a rotating frame, and pulleys 52 and 5 are wound around this rotating frame.
3 is mounted rotatably about its own axis. As is clear from the figure, the rotating frame 51 is connected to the drive shaft 65 of the twice-twist type winding device 6, and the drive shaft 73, which is doubled in speed via gear trains 71 and 72, is connected to the twice-twist type winding device. It is driven and rotated to have the above-mentioned rotation ratio. 6
is a double-twist type winding device and is of a well-known type, so to briefly explain it, 61, 61 are arranged facing each other,
A rotary flyer is integrally rotated by a drive shaft 65 driven by the main motor 7, 62 is a floating frame, 63 is a take-up bobbin provided on the floating frame 62, and 64 is a take-up capstan.

以上が本発明装置の構成であるが、さきに述べたように
予備撚り装置5の回転数は2度撚型巻取装置6のそれと
同方向に約2倍である。
The above is the configuration of the apparatus of the present invention, and as mentioned earlier, the rotation speed of the pre-twisting device 5 is about twice that of the twice-twist type winding device 6 in the same direction.

Therefore, the twisted wires S twisted in the twisting die 3
has already become the finished pitch, that is, the twisting pitch of the final product stranded wire, and the tape 43 is wound and fixed here. This tape-wrapped strand is then 2
The winding device 6 enters the twisting type winding device 6, but since this device 6 is rotated in the same direction as the pre-twisting device 5 and at approximately 1/2 the rotation speed of the pre-twisting device 5, the twisting device 6 enters the twisting device 6. minutes, i.e. device 6
The twist is once untwisted by the number of rotations, but the original finished pitch is restored again at the stage of second twisting before winding. The reason for using the pre-twisting device 5 in the device of the present invention and the effects associated therewith were previously disclosed in the patent application filed by the present applicant (1976-594).

That is, by such pre-twisting, each strand is first given the required amount of twisting, so that uneven twisting and untwisting are completely prevented. Note that the tape winding device 4 is provided upstream of the pre-twisting device 5, but at this position the stranded wire S has already been given the final twist, so there is no particular problem.

However, since the rotation speed of the pre-twisting device 5 is approximately twice the rotation speed of the rotary flyer 61 of the twice-twist type winding device 6 downstream thereof, the stranded wire S wrapped with the tape 43 is 5 and the double twist type winding device 6.
Since the twist is once untwisted by the number of rotations of , and the same twist b is applied again when going to the take-up capstan 64 on the floating frame 62, the de-pu 43 should be suitably elastic. Paper tape, etc., may break. Here, a brief explanation will be given of why twist is imparted to the wire by the intermediate twist imparting device 2 (see Japanese Patent Application No. 48-7120181 of the present applicant for details).

In Fig. 2, the twisting is inhibited between the point P1 and the point P2 where the twisting roller 23 is wound, and the point P
1 upstream of the first twisting prevention point F1 (guide roller 22
) and point P1 (the length is t1), the strand is twisted at the number of revolutions n(t), and the wire is twisted at the number of revolutions n(t).
In the downstream side twisting section (length T2) between this point and the second twisting suppression point F2'4 (guide roller 24) located downstream of this point, the rotation speed -n( It is twisted at t). Now, if the linear speed is v (constant) and the circumference of the groove of the twisting roller is t (=πD), then the part of the wire that passes through the starting point F1 of the upstream twisting section at a certain time t is this twisting section. The degree of twist experienced by T1 (this is the reciprocal of the pitch, that is, the number of twists per unit length) After the same wire portion has traveled a distance (T, +t), that is, (t1 + t)
After /v time has passed, the train passes the starting point P2 of the downstream twist section, and in this twist section, twist turns of T2 given by the following equation are overlapped. Calculating this algebraic sum is easy using a geometric method using a graph.For simplicity, the function n(t) is assumed to be a periodic function with a triangular waveform, and the above equation T1 is calculated using the solid line graph in Figure 3a. Suppose it is expressed.

(Explanation) Tape wrapping is performed on the stranded wires twisted at the finished pitch, so there is no tape loosening or cutting, and the appearance is good.
←The stranded wire is first finished and twisted using a shuttle twisting device, so there is no uneven twisting or untwisting. This eliminates the hassle of replacement, and together with the high-speed performance, the overall efficiency is extremely high. (e) Since a large number of wire bobbins are not rotated, power consumption is reduced.
