The wet paper (or paper stock) 1 carried while being dehydrated by the wire 4 is cut into a tail portion 2 and a portion 3 other than the tail by a water jet from a nozzle (not shown) provided in the wire part. You. The wet paper web 1 that is not adsorbed by the roll 6 is dropped into a pit (in the direction of arrow B) by the wire 4 and is recovered and reused. When the roll 6 is rotated to the position where the roll 6 is attracted, the felt 5 traveling in the direction of rotation of the roll 6 in the high vacuum chamber 7 partitioned by the partition wall of the roll 6.
The wet paper web 1 is strongly adsorbed via the wire 4, is peeled off from the wire 4, and is adsorbed in the low vacuum chamber 8 partitioned by the partition of the roll 6, while being directed in the direction of a first-stage press roll (not shown) (arrow A). However, the portion 3 other than the tail is dropped into the pit (arrow B) by the wire 4 until the tail portion 2 passes through the first-stage press roll. The passage d in the roll 6 communicating with the vacuum device, the high vacuum chamber 7 and the low vacuum chamber 8 are respectively provided with a plurality of large diameter holes 10 and small diameter holes 11.
And maintain the predetermined high and low vacuum levels.

The high and low vacuum chambers 7 and 8 provided in the vacuum suction section of the suction pickup roll 6 so as to cope with the maximum paper width. Since the length in the paper width direction is set, when the paper has a paper width other than the maximum paper width, in particular, when the paper has the minimum paper width, the two vacuum chambers are felt by the felt 5.
7, 8 are covered, but the degree of vacuum in both vacuum chambers is low due to the air permeability of the felt 5. Therefore, the wet paper 1 from the wire 4
In some cases, the tail portion 2 was not smoothly guided to the press part, and the paper passing was unsuccessful. Further, even with the largest paper width, the wet paper web 1 is peeled off from the wire 4 in the high vacuum chamber 7 and the wet paper web 1 is guided in the low vacuum chamber 8. In some cases, the tail portion 2 could not be reliably guided due to the weakness.

In order to adsorb the tail portion, which is a part of the wet paper, which is guided to the wet paper, regardless of the paper width of the wet paper, the passage leading from the vacuum device to the vacuum suction portion of the suction pickup roll is a vacuum for adsorbing the tail portion. A passage leading to the chamber and a passage leading to the high and low vacuum chambers for adsorbing wet paper portions other than the tail portion, and a rotary on-off valve provided in a passage leading to the wet paper portion other than the tail portion. Thus, this is a means for solving the problem.

が出来る。(Operation) By dividing the passage leading to the vacuum suction part into two parts, a tail part and a path other than the tail part, the degree of vacuum of each path can be controlled separately, and a rotary type provided in a path other than the tail part is provided. By adjusting the degree of blockage of the on-off valve, the degree of vacuum in the passage of the tail portion can be increased. Also, the width of the tail part varies slightly depending on the quality of the paper to be formed, but if the paper quality is the same, the width is constant regardless of the width of the paper to be formed, so the vacuum chamber partitioned by a partition having a predetermined constant width. It can be. Therefore, since this vacuum chamber can be moved according to the paper width, there is no reduction in the degree of vacuum that occurs in a vacuum chamber having an extra width that can be expected when movement is impossible, and a high degree of vacuum is maintained regardless of the paper width. I can do it.

A saddle 22 is fitted to 24. Therefore, the vacuum chamber 32 formed by the partition wall 25 that adsorbs the tail portion 2 passes through the passage a of the slide base 26, the passage b of the inner cylinder 24, the passage c of the saddle 22, and the passage h of the duct 31, and a vacuum device (FIG. (Not shown). Further, the passage d of the inner cylinder 23 is connected to the vacuum device via the passage g in which the rotary on-off valve 28 is installed, the passage e of the inner cylinder 24 and the passage f of the saddle 22, and the passage h of the duct 31. . The rotary on-off valve 28 is operated by a cylinder 29 via a lever 30 to adjust the opening degree of the passage g. When the opening degree of the passage g is reduced by the rotary on-off valve 28, the degree of vacuum in the passage f decreases, and the degree of vacuum in the vacuum chamber increases in accordance with the degree of vacuum in the passage c. Note that the vacuum chamber 32 at the time of the maximum and minimum paper widths according to the present invention is used.

Guidance is reliably performed. Also, the degree of vacuum in the vacuum chamber at the tail can be freely controlled by a rotary on-off valve provided in a passage to the high and low vacuum chambers that adsorbs parts other than the tail. Further, since the width of the tail portion is substantially constant, the degree of vacuum in the vacuum chamber of the tail portion can always be kept high by moving the vacuum chamber having the constant width regardless of the width of the paper to be formed.
