 In the automatic wallpaper gluing machine according to the present invention, while the sheet-shaped wall covering is moved along a predetermined path by a plurality of rolls which are rotationally driven in conjunction with the motor, the glue in the glue tub is moved by the gluing rolls. In an automatic wallpaper gluing machine that continuously transfers and coats on the back surface of wall coverings, the lower roll of the entrance side pinch roll is supported by a vertical slot or U-shaped hole provided in the frame side plate. ..

[0008]

[Action]

 In the present invention, since the lower roll of the pinch roll is supported by the vertically elongated hole or U-shaped hole provided in the frame side plate, the bearing of the lower roll is moved upward in the elongated hole during cleaning. By moving the lower roll and the doctor roll, the gap between the lower roll and the doctor roll can be widened, and at the same time, the lower roll rotation transmission gear can be isolated and stopped rotating, or the bearing of the lower roll can be removed from the U-shaped hole. By removing the lower roll completely, it is possible to eliminate the dangerous roll interval itself. Therefore, the gluing roll and the doctor roll, which require the most washing, can be safely washed with rotation by the motor.
