- the adjustment of the bonding position between the core and the liner is left to the manual adjustment by the operator, and the operator checks the bonding state of the liner and the core, and checks the bonding state between the liner and the core. If the paper ends are misaligned, move at least one of the mill roll stand supporting the core base paper roll or the minorole stand supporting the liner base paper roll in the width direction. The position of the core and the liner was adjusted.
- Glue is used for bonding the core and the liner, and the single facer is provided with a gluing device as a device for supplying this glue.

Is being solved. To be more specific, the right and left paper edge positions of the two web materials are compared with each other, and the inner paper edge is compared. The positions of the left and right glue dams are adjusted to match the position. Since the gluing position is determined by the positions of the glue dams on the left and right sides, by adjusting the position of each glue dam to the inner edge of the paper in this way, the area where the core glue adheres may protrude from the bonding surface. This eliminates wasteful consumption of glue and prevents the generation of dirt and defective products due to excess glue adhesion. .

- the paper width of the web material shrinks due to the heating by the heating roll,
- the position in the machine width direction changes before and after heating by the roll. Therefore, by detecting the position on the heating roll in the immediate vicinity of the bonding location or on the downstream side of the heating roll, it becomes possible to accurately detect the position in the machine width direction of each web material at the time of bonding. . More preferably, the position of the web material on the heating roll is detected. The flapping of the web material on the heating roll is suppressed, so that more accurate detection is possible.
- the displacing means may be configured to move a web roll of web material in the machine width direction, or may be configured to rotate in a plane parallel to the axis of the roll.
- the running position of the web material is also linked and slides in the moving direction of the base paper roll.
- the running position of the web material gradually changes in the machine width direction by rotating the web roll to provide an angle between the direction in which the web material is fed from the web roll and the line traveling direction.
- Data relating to the position in the machine width direction of each web material (for example, paper width data, data of expansion ratio with respect to moisture content and temperature, etc.) is obtained in advance, and based on the data, one of the web materials is controlled by the control means.
- the displacement means is controlled so as to fit inside the web material, and the running position of each web material is preset. According to this, in the feedback control after the start of the operation, the traveling position of the web material can be adjusted to an appropriate traveling position at an early stage, and the waste of paper consumption and glue consumption can be further reduced. it can.

This makes it possible to accurately adjust the position of the glue dam in accordance with the paper end position of the core, and to suppress the generation of dirt and defective products due to excess glue sticking out of the core, and to reduce paper consumption and glue consumption. Waste of quantity can be reduced.

For example, when a motor is used as a driving source of the moving means, it can be easily realized by applying the inverter control. By performing such variable speed control, it is possible to move the glue dam to a desired position with high accuracy. It is also conceivable that the running position of the center is shifted in the machine width direction.
- the position of the glue dam may be adjusted according to the position of the shifted core, but preferably, the position of the glue dam is adjusted after adjusting the position of the core to a predetermined reference position.
- the center position detecting means detects the center position in the width direction of the core on the heating roll immediately adjacent to the gluing roll or on the downstream side of the heating roll.
- the control means calculates the deviation between the center position detected by the center position detection means and the reference position, and controls the displacement means for changing the running position of the center in a direction to eliminate the deviation.
