However, the conventional suction / disposal device sucks regardless of the web transport speed, and when the transport speed becomes high, the ears of the slitted edge portion increase and the suction is insufficient, and the ears are ducted. If the trouble of clogging inside occurs and the conveying speed becomes slower, not only the energy of suction is wasted, but also the sucked edge portion is easily cut off, and the suction of the edge portion becomes unstable. This tendency is more likely to occur as the thickness of the web becomes thinner, and becomes a problem particularly with paper having a basis weight of 50 g / m 2 or less.

In order to achieve the above object, the present invention slits the edge portion 6 of the continuously running web 1 and then sucks and discards the ear 8 of the slitted edge portion 6. The ear feeding fan 9 for feeding, the feeding speed detector 12 for detecting the feeding speed of the web, and the ear feeding fan 9 for sucking and discarding the sucking speed increases as the feeding speed of the web 1 increases. The edge suction / disposal device is provided with the controller 13 for controlling as described above, and the conveyance speed of the web 1 is detected. As the detected web conveyance speed becomes faster, the suction speed of air at the time of suction / disposal becomes faster. The edge suction and disposal method is characterized in that the ears are discarded stably regardless of the change in the web transport speed.

The relationship between the transport speed of the web 1 and the suction speed in the duct of the ear feeding fan 9 is as follows. The suction speed should also be slowed. Therefore, in the present invention, the suction speed is varied according to the transport speed of the web 1 to stably realize the suction and discard of the ears 8 of the slitted edge portion 6. The suction speed varies depending on the width of the edge 8 of the edge portion 6 and the thickness of the web, but is preferably controlled within a range of 1 to 2 times the transport speed of the web 1, and more preferably 1 to.
It is necessary to control within the range of 1.5 times. The present invention is particularly effective for paper having a basis weight of 50 g / m 2 or less.
