Transport cylinder gripper pad height adjustment device

A transport cylinder gripper pad height adjustment device includes a first notch (4) formed in the outer peripheral portion of a transport cylinder (1) in the cylinder axial direction, a gripper pad (6) which is equipped in the first notch and grips a sheet in cooperation with a gripper (5), a gripper pad bar (20) which has a bottom surface (20a) inclined with respect to the cylinder axial direction, has the gripper pad (6) fixed on it, is restricted in movement in the cylinder axial direction, and is supported to be movable in the cylinder radial direction, a first adjusting bar (16) which has an inclined, upper surface (16a) in contact with the bottom surface (20a) of the gripper pad bar (20), and is supported to be movable in the cylinder axial direction in the first notch (4), a biasing member (26) which biases the bottom surface (20a) of the gripper pad bar (20) against the upper surface (16a) of the first adjusting bar (16) in the direction to bring them into press contact with each other, a drive shaft (55) which is supported to be movable in the cylinder axial direction at the center of rotation of the transport cylinder (1), a driving unit (72) which moves the drive shaft (55) in the cylinder axial direction, and a first connecting portion (71) which is interposed between the drive shaft (55) and the first adjusting bar (16), and moves the first adjusting bar (16) in the cylinder axial direction as the drive shaft (55) moves.
