き、切断作業の能率を向上させることができる。Now, it is assumed that the first and second conveyors operate together and the belt-shaped member is conveyed in the longitudinal direction by the first and second conveyors. When the cutting line of the belt-shaped member intersects the space between the first and second conveyors, the cutting blade is moved in the space in the width direction of the belt-shaped member while conveying the belt-shaped member to move the belt-shaped member. Disconnect, but at this time
At least one of the transport speed of the first and second conveyors or the moving speed of the cutting blade is controlled by the control means, and the cutting direction by the cutting blade and the extending direction of the cord are substantially matched. As a result, the strip-shaped member is cut along the cord by the cutting blade on the cutting line, and the strip-shaped piece is cut out on the second conveyor. At this time, since the cutting blade extends substantially along the cord of the strip-shaped member as described above, there is little mutual interference between the cutting blade and the cord of the strip-shaped member at the time of cutting, and as a result, the cutting work of the strip-shaped member is smooth. To be done. Further, since the cutting blade cuts the strip-shaped member stretched over the space between the first and second conveyors, a special anvil for separating the strip-shaped member from the conveyor and a means associated with the anvil are not required. The structure is simple and the manufacturing cost can be low. Next, the second conveyor is operated to convey the cut strip, at this time,
Since the remaining strip-shaped members following the strip-shaped pieces are placed on the first conveyor that is inactive, it is not necessary to lift the strip-shaped member, and as a result, the structure is simple and the manufacturing cost is low. it can. In addition, when there is a slight change in the inclination angle of the cord in the belt-shaped member, the cutting blade can be operated by changing at least one of the conveying speed of the first and second conveyors or the moving speed of the cutting blade. The cutting direction can be easily made to follow the extending direction of the cord after the change, and the efficiency of the cutting work can be improved.

Cutting edge for cutting because it extends almost along 28
Mutual interference between 53 and the cord 28 of the strip-shaped member 27 is small, and as a result, the cutting operation of the strip-shaped member 27 is smoothly performed. Also,
Since the cutting blade 53 cuts the strip-shaped member 27 stretched over the space 19 between the first and second conveyors 11 and 18, it is a special anvil for separating the strip-shaped member from the conventional conveyor. Also, the air jetting means associated with the anvil is not required, the structure is simple and the manufacturing cost can be reduced. Further, the cutting of the strip-shaped member 27 is started from the middle in the width direction to the one (left) side end, and then it is reversed so as to be cut from the middle to the other (right) side end. When the cutting is started from, the winding of the belt-shaped member 27 that occurs at the cutting start portion is prevented. When the strip-shaped member 27 is cut along the cutting line D as described above, the operations of the first and second motors 16 and 24 and the motor 56 are stopped. A parallelogram-shaped strip 67 whose length is the same as the cutting length L and whose start and end are inclined at the same angle as the cord 28 is cut out.
