A belt drive device for driving these endless belts and a pressing means for pressing these endless belts toward the joint part are moved in the joint passing direction of the joint part. is there.

The second means adopted by the present invention is for finishing a plurality of joints, which are stretched above the tile panel carry-in space with a space between adjacent joints so as to come into contact with a joint part of the tile panel carry-in space. The endless belt, the belt drive device that drives these endless belts, the pressing means that presses these endless belts toward the joint portion, and the tile panel transfer device that is attached to the tile panel carry-in space are provided. is there.

The first and second means may be provided with a belt cleaning device that comes into contact with the endless belt. Further, the cross-sectional shape of the endless belt may be circular or elliptical.

[0007]

In the first means, when the apparatus body is moved in the joint passing direction of the joint portion in the state where the tile panel is carried into the tile panel carrying-in space, the device is pressed by the pressing means and the belt driving device. The jointless endless belt driven by moves in the joint passing direction while contacting the joint surface of the tile panel. During this movement, the joint finishing endless belt removes excess joint material on the joint surface and smoothes the joint surface.

In the second means, when the tile panel is moved in the tile panel carry-in space by the tile panel transfer device, the joint endless belt pressed by the pressing device and driven by the belt drive device is moving. While moving in contact with the joint surface of the tile panel, it moves relatively in the joint passing direction. The jointless endless belt removes excess joint material on the joint surface and smoothes the joint surface during this relative movement.

In the first or second means, when the belt cleaning device is provided, the joint material adhered to the joint finishing endless belt at the time of removing the joint material is removed by the belt cleaning device. Therefore, the joint endless belt comes into contact with the joint surface in a cleaned state. The cross-sectional shape of the joint surface can be changed by selecting the cross-sectional shape of the endless belt as a circle or an ellipse.
