Abstract:
A printing-cylinder bearing device for causing a supporting member to rotating support a printing cylinder in such a manner that the printing cylinder can be moved between a printing position and a non-printing position, the improvement comprisingradial-load supporting means having between the supporting member and a shaft of the printing cylinder at least an eccentric part that can be rotated around the centerline of a hole provided on the supporting member and has a hole whose centerline is misaligned with the hole provided on the supporting member, a housing that is provided interlocked with the eccentric part and in such a manner as to inhibit the axial movement of the printing cylinder with respect to the supporting member, thrust-loading supporting means provided between the housing and the shaft of the printing cylinder and separately buttressing said printing cylinder with said radial-load supporting means, and eccentric part rotating means for causing the eccentric part to rotate around the centerline of the hole on the supporting member and can hold the rotated position of the eccentric part.
