ABSTRACT:
An apparatus fixedly attaching transformer to a rotary drum is provided with a pressing means. The pressing means includes a holder driven by a driving means; a rod-shaped supporting member, whose one end is attached to the bottom of the holder, and the other end is removably provided with a portion having a larger diameter than that of the supporting member; a cap movably fitting around the circumferential surface of the supporting member at the end proximal to the holder in such a way that its vertical position is allowed to be adjusted; a ring provided with a groove for accommodating a part of the larger diameter portion of the supporting member, wherein the ring is used for applying a uniform pressure to the rotary transformer and fits around the circumferential surface of the supporting member at the end distal to the holder; and a resilient member for providing an elastic force to the ring located between the cap and the ring in such a way that the ring is allowed to apply a uniform pressure on the upper surface of the rotary transformer during the pressing operation thereof, thereby fixedly attaching the rotary transformer to the drum.
