Abstract
An axial-position adjustment apparatus is used to adjust the axial position of an arm shaft equipped with paper roll support arms. The arm shaft is supported rotatably and axially movably on a frame in a paper web feed unit and rotated by means of a shaft-rotating apparatus located at one end portion of the arm shaft. The axial-position adjustment apparatus has a moving member including a male screw and connected to the arm shaft in such a manner as to be rotatable and axially immovable in relation to the arm shaft; a guide member having a threaded hole formed therein, the male screw of the moving member being screwed in the threaded hole, and the guide member being provided in such a manner as to be nonrotatable and axially immovable in relation to the frame; and a drive unit for rotating the moving member. The moving member and the guide member are located adjacent to the shaft-rotating apparatus. The drive unit is provided on a support member axially immovably connected to the arm shaft.
