However, as described above, the lower pinch roll 27b of the main body of the gluing machine has a crown shape in which the diameter of the central portion is continuously larger than the diameters of both end sides, In order to move the cloth to be inserted to the center of the roll, if the original cloth pull-in position is attached at a position displaced from the center, the cloth will meander and pull in the initial pull-in state. As a result, the slitter cuts the cross edge of the cloth, which is not a straight line, resulting in a meandering thing.

Further, even when the cloth is attached at a position displaced from the center with respect to the cloth core rod, the cloth to be drawn in is to be moved to the center portion of the roll, so that the drawing port and the cloth core rod are inserted. Are shifted to each other, the cloth itself is bent in the lateral direction, wrinkles are easily generated, and unevenness in gluing is easily generated. Further, this positional deviation is a force that tries to prevent the retracted cloth from moving toward the center of the roll, and there is a problem that the meandering of the cloth becomes difficult to converge.

Therefore, in preparation for the gluing work, the mounting position of the cross core rod of the wound cloth and the drawing position of the cloth are positioned with great care. Note that the overstay of the slitter is provided with a scale for aligning the upper and lower rotary blades, but it is far from the lead-in port of the cross core rod or slitter and the alignment should be sufficiently accurate. I couldn't.

The present invention makes it easy to set the wall covering at a predetermined position of the slitter, and to prevent the meandering of the cut side of the side end of the wall covering by cutting the wall covering while retracting. To aim. In addition, it facilitates the alignment of the wound wall covering material with respect to the wall covering material core rod at the time of mounting, makes it difficult to generate wrinkles, and makes it difficult to cause unevenness in gluing.
The purpose is to facilitate the convergence of the meandering of the cross.
