The clearance (transfer pattern) of the transfer roll 40 is applied to the surface of the plate 45 by adjusting the clearance between the transfer roll 40 and the plate 45 by a clearance adjusting device 43 that adjusts the clearance.
Can be transferred very beautifully.

As the clearance adjusting device, for example, a configuration using a ball screw 46 and a ball nut 47 can be employed. The ball screw 46 is fixed at both ends so that it cannot move in the vertical direction, but has a mechanism that can freely rotate in the rotation direction. On the other hand, a ball nut 47 that fits into the ball screw 46 is attached to a bracket (not shown) that supports the transfer roll 40 and the paint supply roll 41, and further has a slide bar 48 that can move up and down. . In this state, the ball screw 4
When the ball screw 6 is rotated, the ball nut 47 fitting with the ball screw 46 moves upward or downward according to the rotation direction of the ball screw 46. Accordingly, a bracket (not shown) supporting the transfer roll 40 and the paint supply roll 41 integrated with the ball nut can move up or down, and as a result, the clearance between the transport conveyor 44 and the transfer roll 40 can be increased. Adjustments can be made easily. Furthermore, if a scale is cut on a bracket (not shown) that supports the transfer roll 40 and the paint supply roll 41 so that the movement amount of the ball nut 47 can be known, it is convenient to adjust the clearance.
