<p>PROBLEM TO BE SOLVED: To enable an upper roller and a lower roller that treat a treatment workpiece to be simply repaired and exchanged by separating these rollers in the vertical direction and moving them to a take-out position.SOLUTION: When an upper roller 10 and a lower roller 20 that treat a treatment workpiece W are moved in a direction crossing a feed direction of the treatment workpiece as these rollers remain separated in the vertical direction to be guided from a position where the treatment workpiece is treated to a take-out position, an upper rail 12 is made to hold an upper roller holding part 11 that holds the upper roller rotatably to couple a lower roller holding part 21 that holds the lower roller rotatably to be separable from the upper roller holding part with a telescopically movable coupling member 30. At a position to which the upper rail is raised by a first hoist unit 14, a holding member 40 provided by separating from the upper rail is made to hold one end of the upper roller holding part guided to the take-out position.</p> |
