Further, the sensor 154 is configured such that the cutting device 16 can detect the outer diameter of the blade product Br immediately after the cutter 141. Thereby, the outer diameter of the braid product Br can be detected in the vicinity of the position where the braid product Br is cut. That is, since the mandrel M is cut immediately after the rear end thereof, the blade product Br can be cut without the cutter 141 of the cutting device 16 coming into contact with the mandrel M.

In the above structure, the sensor 161 and the sensor 154 sandwich the braided product Br near the rear end of the mandrel M included in the braided product Br. The sensors 161 and 154 are controlled by a controller (not shown), and the detection values of the sensors 161 and 154 are input to the controller. Further, an encoder pulse of a drawer conveyor for sending the braid product Br (not shown) is input to the controller. The amount of movement of the braided product Br can be recognized from the encoder pulse of the drawing conveyor, and the sensor 16 before the rear end of the mandrel M reaches the wrapping unit 4.

When the rear end of the mandrel M passes through the sensor 161 of the wrapping unit 4 by being pinched and detecting a rapid decrease after the distance between the contact rollers 163 and 163 increases.

In the controller, the encoder pulse of the pull-out conveyor is stored when the sensor 161 of the wrapping unit 4 recognizes the passage of the rear end of the mandrel M. That is, the timing of cutting the braided product Br is calculated by the interval at which the encoder pulse of the drawer conveyor is detected. Further, the contact rollers 163, 163 of the sensors 161, 161 are opened again after recognizing the rear end of the mandrel M so that unnecessary resistance is not applied to the braid product Br.

When the front end of the braided product Br is sent backward and reaches the cutter portion 5, the holding device 121
The front end of the braided product Br is clamped by the chuck 122. The holding device 121 moves according to the delivery speed of the braid product Br. When the position considered to be the rear end of the mandrel M contained in the braided product Br reaches the position of the cutting device 16, the arm 149 pivots downward to move the braided product Br to the rollers 154 of the sensors 154 and 154.
It is clamped by a.154a. The roller 154a-1
54a changes the detection diameter of the rollers 154a and 154a according to the feeding of the braid product Br as described above, and the large diameter portion is nipped by the rollers 154a and 154a, and the feeding reaches the inner and smaller diameter portions of the mandrel, and the nipping interval is The reduced position is detected by the proximity switch of the sensor 154, and the encoder pulse of the feed conveyor at the time of detection is stored in the controller (not shown).

As described above, in the controller (not shown), from the encoder pulse of the feed conveyor,
The length of the braided product Br including one mandrel is calculated. The length of the mandrel M is constant, and the front end of the mandrel M is located on the delivery side by the unit length of the mandrel M from the rear end position of the mandrel M detected by the sensor 161. In this way, the positional relationship between the mandrel M that has passed the sensor 161 and the mandrel M that has passed the sensor 154 is calculated, and it is recognized whether or not the mandrel M exists at the cutting position of the blade product Br by the cutter 141.

That is, in the controller, if the calculated length of the braid product Br is a specified value, it is determined that the braid product Br can be cut, and the blade product Br is cut by the cutter 141. If the length of the blade product Br is out of the specified value, an error message is displayed on the display device (not shown) connected to the controller and the machine stops.

As shown in FIG. 17, when the braid product Br is sent out and the portion considered to be the rear end of the mandrel Mb reaches the position of the sensor 161, the braid product Br is nipped by the roller 163, and the sensor 161 detects the mandrel Mb of the mandrel Mb. Recognize the rear end. Further, when a portion of the mandrel Ma which seems to be the rear end of the mandrel Ma reaches the position of the sensor 154, the roller 154a clamps the braided product Br and recognizes the rear end of the mandrel Ma. In FIG. 17, the mandrel M
