The twisted pair wire (W3) having passed through the second twist imparting and guiding roller (15) is drawn out of the hollow portion of the fourth hollow horizontal main shaft (13).

FIGS. 2 and 3 show an apparatus for twisting four twisted pair wires (W3) obtained as described above on the same line. In the figure, "front" means the left side, "rear" means the right side, "left" means the left side from the rear to the front, and "right" means the right side in the same manner.

In the front and rear casings (32) and (33), a pair of twisted pair devices (D) are arranged side by side.
In front of the front casing (32), one take-up side twisting machine (shown in the drawing) twists four twisted pair wires (W3) unwound from the four twisted pair devices (D) to form a product twisted wire. (Not shown), and a take-up means (E) for taking out the four twisted pair wires (W3) in parallel is disposed between the twisted holes (not shown). A take-off means (E) comprising a drive wheel (34) having a polyurethane non-slip layer on the peripheral surface and being diverted to the peripheral surface such that four parallel twisted pairs (W3) are pulled; (34)
Arc-shaped portion (35) that contacts the twisted pair wire (W3)
a) and a driven endless belt (35) to which the power of the drive wheel (34) is transmitted via a twisted pair wire (W3).

In the upper part of the front wall of the front casing (32) and slightly above the front wall of the rear casing (33), guide rollers (36) and (37) for feeding out twisted pair wires are provided as a pair of left and right twisted wire devices ( In correspondence with (D), two are provided so as to protrude forward. The twisted pair wire (W3) drawn out from the pair of twisted pair wire devices (D) in the front casing (32) is drawn out from an opening formed in the front wall of the front casing (32) and is guided by guide rollers (36). ) It is designed to be lowered from below to above. Rear casing
Twisted wire unreeled from a pair of twisted wire devices (D) in (33)
(W3) is drawn out from an opening formed in the front wall of the rear casing (33), and from under the guide roller (37), the front casing (33).
The guide roller (32) is guided on a guide roller (38) provided to project rearward and upward from the rear end. By the way, two guide rollers (36) on the front wall of the front casing (32) and two guide rollers (36) on the front wall of the rear casing (33).
The feeding position of the twisted pair wire (W3) is separated from the two guide rollers (37) in the front and rear directions. As a result, in this state, the tips of the four twisted pair wires (W3) are not aligned at the twist opening.
In order to eliminate this problem, disposed on the front casing (32) are an upper guide roller for adjustment (39) and a lower guide roller for adjustment (40), each of which is two. The two upper guide rollers for adjustment (39) are provided at a large distance from each other so as to protrude forward and upward at the upper end of the front wall of the front casing (32). The two adjusting lower guide rollers (40) are provided on a front wall of the front casing (32) so as to protrude forward and vertically at intervals from a bracket (4).
It is supported by a vertical support bar (42) that is stopped by 1). Then, the twisted pair wire (W3) fed from the twisted pair wire device (D) in the front casing (32) is fed from the guide roller (36) for feeding through the lower guide roller (40) for adjustment and used for adjustment. It is diverted in a U-shape to reach the upper guide roller (39). Similarly, between the two upper guide rollers (39) for adjustment, the guide is fed out of a pair of twisted pair devices (D) in the rear casing (32) so as to be at the same height position. Two guide rollers (43) for guiding the twisted pair wire (W3) passing through the roller (38) to the take-up means (E) are arranged. The twisted pair wire (W3) fed from the pair of twisted pair devices (D) in the front casing (32) and reaching the adjustment upper guide roller (39) is U
The amount of detour is determined so that all the tips of the four twisted pairs (W3) coincide when passing through the four guide rollers (39) and (43).

At the front of the front casing (32), a partition-like vertical wall (44) for taking-up means is set up so as to extend in the front-rear direction. At the front end of the vertical wall (44), an upward protrusion (44a)
A guide roller (39) (4
Drive wheel (34) with four twisted pairs (W3) passing through 3)
A guide roller (45) for lowering from the upper front to the lower side is disposed. Directly below the guide roller (45) at the front end of the vertical wall (44), a twisted pair wire (W3) descending downward is driven by the drive wheel (3).
A guide roller (46) is provided at the upper end of the drive wheel (34) from above in front of 4) to be directed horizontally. Vertical wall
At the front end of (44), a front protruding portion (47) is provided substantially at the center of the height, and guide rollers (48), (49) are arranged before and after this. And the front and rear guide rollers (48) (49)
The horizontal arm (51) attached to the front end and the rear end of the horizontal arm (51) are rotatably attached to the lower end so that the dancer roller (50) is located below the middle of the horizontal arm. A vertical lever (52) and a bracket (53) which is rotatably mounted on the upper end of the lever (52) and is provided on the vertical wall (44) are arranged. In the middle of the length of the horizontal arm (51), the tip of the piston rod of the downward hydraulic cylinder (54), whose base end is rotatably mounted on the vertical wall (44), is rotatably mounted. Have been. Then, the rear guide roller (49) guides the twisted pair wire (W3) surrounding the second half circumference of the drive wheel (34) horizontally forward and then toward the dancer roller (50). Front guide roller (48)
Is a twisted pair wire (W3) around the lower half of the dancer roller (50)
To the twister. Guide roller (45) (4
6), (48), (49) and the dancer rollers (50) are each four, and are arranged in parallel at close intervals.

The four twisted pair wires (W3) are connected to a drive wheel (34),
When the driving wheel (34) is rotated clockwise in FIG. 2 with the driven endless belt (35) sandwiched between the arc-shaped portions (35a), the driving wheel (34) is rotated through the twisted pair wire (W3). Is transmitted to the driven endless belt (35), and the driven endless belt (35) rotates counterclockwise. As a result, in combination with the presence of the non-slip layer of the drive wheel (34), the four twisted pair wires (W3) are reliably and uniformly pulled without slipping on the peripheral surface of the drive wheel (34).
