ずることがない。According to the present invention, the transport length of each cut strip from the cut portion to the cut portion is adjusted so that the positional phase of each cut strip is the same at the cut portion. Therefore, in the conveyance process after each slit band material is cut, the positional phase in the transport direction is deviated from each other due to synergies such as thickness unevenness and extension of the band material itself, or a slight difference in applied tension. Even in such a case, the deviation amount is offset by the conveyance length adjustment amount given to each slit band member. Therefore, the respective band-shaped members are simultaneously cut by a single cutting machine in a state where the positional phases of the respective band-shaped members are in the same phase, and no error occurs in the cutting position.

The position of the mark a detected by the mark detector 31A is displaced from the position of the mark b detected by the mark detector 31B by Δa in the forward direction. If the positional phase of the cut strip 1C is delayed from the center cut strip 1B by Δc,
The position of the mark c detected by the mark detector 31C deviates from the position of the mark b detected by the mark detector 31B by Δc in the delay direction.

In order that the deviation amounts Δa and Δc between the phases of the marks a to c of the respective cut strip-shaped materials 1A to 1C detected by A to 31C become zero,
The transport length adjusting devices 32A and 32C are controlled. The amount of advance deviation Δ of the above-mentioned cut strip 1A with respect to the cut strip 1B
The a is zero-adjusted by lowering the mark alignment roll 33A by a predetermined amount by the transport length adjusting device 32A to increase the transport length of the strip 1A from the cutting portion to the cutting portion. In addition, the cut strip 1B of the cut strip 1C described above
The delay deviation amount Δc with respect to is obtained by raising the mark alignment roll 33C by a predetermined amount by the transport length adjusting device 32C.
Zero adjustment is performed by reducing the transport length of the strip 1C from the cutting portion to the cutting portion. As a result, the conveyance length of each of the cut strips 1A to 1C from the cut portion to the cutting portion is adjusted, and all the three strips 1 at the entrance of the double cutting machine 20 are adjusted.
The position phases of A to 1C are matched.

According to the present invention, the transport length from the cut portion to the cut portion of each cut strip material 1A to 1C is adjusted so that the positional phase of each cut strip material 1A to 1C is the same at the cut portion. Therefore, in the conveyance process after cutting each of the cut strips 1A to 1C, the positional phases in the conveyance direction are deviated from each other due to synergies such as thickness unevenness and elongation of the strip itself or a slight difference in applied tension. Even in the case of performing such adjustment, the deviation amount is offset by the conveyance length adjustment amount applied to each of the slit-shaped strip materials 1A to 1C. Therefore, the band-shaped members 1A to 1C are simultaneously cut by the single cutting machine 20 in a state where the positional phases of the band-shaped members 1A to 1C are in the same phase, and no error occurs in the cutting position.
