The length of the shuttle 40 is set to be at least twice the maximum distance between the distance between the end wall of the recess 84 and the core wire 6 and the distance between the core wires 6. For example, the maximum distance between the distance between the end wall of the concave portion 84 and the core wire 6 and the distance between the core wires 6 is the concave portion 84.
The length L2 of the shuttle 40 is set so as to satisfy the relationship of L2 ≧ 2L1, where L1 is the distance L1 between the one end wall 84a and the leftmost core wire 6 in FIG. In FIG. 1, illustration of the warp yarn 7 and the weft yarn 8 is omitted.

Although not shown, the lead 38 has a large number of vertical steel partition plates, and the core wire 6 and the warp yarn 7
In the weaving flat cable 1, the cables pass one by one between the partition plates adjacent to each other in a state of being arranged in the actual arrangement. The interval between the adjacent partition plates is set to be substantially equal to the diameter of the core wire 6 or the warp 7 passing therethrough. That is, a large number of partition plates are arranged at irregular pitches in accordance with the diameter and arrangement of the core wires 6 and the warp yarns 7.

Next, the operation will be described. The multiple cores 6 supplied by the core supply device 10 and the multiple warps 7 supplied by the warp supply device 11 are guided by the distribution guide device 12,
It is guided between the upper pressing roll 43 and the lower pressing roll 44 through the heald 37 and the lead 38 of the weaving machine 13. Now, assuming that the weaving machine 13 forms the weaving section 2, the control device
82 sets the electromagnetic brake device 53 to the brake non-operation state,
The toothed electromagnetic clutch device 66 is disconnected, the second electric motor 64, the actuator 79, and the vibration generating device 81 are not activated, and the first electric motor 47 is activated. The rotating power of the output shaft 48 of the first electric motor 47 is transmitted to the first crankshaft 55 via the pulley 49, the belt 52, the pulley 51, the shaft 50, the pulley 54, the V-belt 57, and the pulley 56, 1 crankshaft 55
Rotates around the axis. As a result, the connecting rod 41a reciprocates linearly at a predetermined cycle, the slay 41 reciprocates a predetermined angle around the lower end, and the pawl 78 intermittently moves the ratchet wheel 77 through the power transmission mechanism 78a. Rotate the angle. The rotating power of the first crankshaft 55 is the gear 58 and the gear
The second crankshaft 59 is transmitted to the second crankshaft 59 via 60 and the second crankshaft 59 rotates around the axis. The number of teeth of gear 60 is gear
This is twice the number of teeth of 59, and the second crankshaft 59 makes one rotation while the first crankshaft 55 makes two rotations. As a result, the connecting rod 37a performs a predetermined well-known reciprocating linear motion, and the heald 3
7 alternately moves up and down, the connecting rod 61a makes a reciprocating linear movement at a predetermined cycle, and the shuttle driving device 61 drives the shuttle holder 62 to cause the shuttle 40 to reciprocate linearly along the shuttle race 39. That is, one of the two healds 37 for the core wire 6 and one of the two healds 37 of the warp thread 7 rise, and the other heald 37 of each falls, and the slay 41 becomes the heald 37. Shut down to the shuttle
When the shuttle 40 is thrown out of one shuttle holder 62 and received by the other shuttle holder 62, the shuttle 40 traverses the opening 36 in a direction orthogonal to the core wire 6 and the warp 7, and the weft 8 accommodated in the shuttle 40 Is woven into the core wire 6 and the warp yarn 7. And the rotational power of the ratchet wheel 77 is the shaft 68, the gear 71, the gear 73, the shaft 72, the gear 74, and the gear 76.
Is transmitted to the lower press roll 44 via the shaft 75 and the lower press roll 44, and the lower press roll 44 rotates by a predetermined angle around the axis. As a result, the woven flat cable 1 sandwiched between the upper holding roll 43 and the lower holding roll 44 is taken up by a predetermined length.
Further, the other of the two healds 37 for the core wire 6 and the other of the two healds 37 for the warp 7 rise, one of the healds 37 descends, and the slay 41 becomes the heald 37. The shuttle 40 is thrown out of the other shuttle holder 62 and received by the one shuttle holder 62 in a state of swinging to the side, so that the shuttle 40 traverses the opening 36 in a direction orthogonal to the core wire 6 and the warp 7. The weft 8 accommodated in the shuttle 40 is woven into the cord 6 and the warp 7. Then, the woven flat cable 1 sandwiched between the upper pressing roll 43 and the lower pressing roll 44 is taken out by a predetermined length. When the slay 41 swings to the side opposite to the heald 37, the weft 8 is narrowed down to a predetermined pitch by the lead 38. Hereinafter, the same operation is repeated, and the weaving portion 2 is formed.

On the other hand, the rotation speed of the shaft 68 is detected by the rotary encoder 80, and the output signal of the rotary encoder 80 is supplied to the control device 82. Accordingly, the control device 82 calculates the take-up length of the weaving flat cable 1 by the upper holding roll 43 and the lower holding roll 44, and activates the actuator 79 when the weaving portion 2 is formed to the predetermined length. As a result, the engagement between the ratchet wheel 77 and the pawl 78 is released, and the lower pressing roll 44 does not rotate. Therefore, the weft yarn 8 is woven into the core wire 6 and the warp yarn 7 at the same position, and the densely woven portion 4 is formed.

After operating the actuator 79 for a predetermined time, the control device 82 puts the first electric motor 47 into a non-operation state and simultaneously puts the electromagnetic brake device 53 into a brake operation state,
At the same time, the toothed electromagnetic clutch device 66 is connected, and the actuator 79 and the vibrating device
Put 81 in operation. As a result, the rotational power of the output shaft 65 of the second electric motor 64 is changed by the toothed electromagnetic clutch device 66, the pulley 67, the belt 70, the pulley 69, the shaft 68, the gear 71, the gear 73, the shaft 72, and the gear.
It is transmitted to the lower presser roll 44 via the gear 74, the gear 76, and the shaft 75, and the lower presser roll 44 continuously rotates, and the weaving flat sandwiched between the upper presser roll 43 and the lower presser roll 44. The cable 1 is continuously taken. At this time, the first crankshaft 55 and the second crankshaft 59 do not rotate, and the weaving device 33 does not operate.
The non-woven portion 3 is formed without weft 8 being woven into the fabric. Also, at this time, the core wire 6 with the heald 37 stopped.
Is continuously taken, a large frictional force acts on the heald 37, and there is a possibility that the core wire 6, the heald 37, or the like may be damaged. Since vibration is applied to the core wire 6, frictional force is reduced, and damage to the core wire 6 and the heald 37 can be prevented well. On the other hand, the rotation speed of the shaft 68 is detected by the rotary encoder 80, and the output signal of the rotary encoder 80 is
Supplied to Thereby, the control device 82 calculates the take-up length of the weaving flat cable 1 by the upper pressing roll 43 and the lower pressing roll 44, and when the non-woven portion 3 is formed to the predetermined length, the second electric motor 64 is turned on. The first electric motor is set in the non-operating state and the toothed electromagnetic clutch device 66 is set in the non-connected state.
47 is activated, the electromagnetic brake device 53 is deactivated, and the vibration generator 81 is deactivated. Thereby, the densely woven portion 4 is formed.

Hereinafter, the same operation is repeated, and the woven flat cable 1 having the woven parts 2 and the non-woven parts 3 alternately and having the densely woven parts 4 at both ends of the woven part 2 is woven.

When the woven flat cable 1 is used, the woven flat cable 1 is cut at the non-woven portion 3 to obtain a woven flat cable 1 having a desired length, and an adhesive is applied to both ends to connect the connector. I do.
