ABSTRACT:
A coating apparatus comprises a carrier movable in a to-and-aft direction, a swing frame having a portion pivotably supported by the carrier, three pairs of bearings mounted to the swing frame, and three rolls journaled by the three pair of bearings, respectively. A drive unit includes three variable speed motors which include respective output shafts connected to the corresponding rolls through offset shaft couplings. The three rolls have respective axes which are connected to form an imaginary triangle. That portion of the swing frame which is pivotably supported by the carrier is located outside of the imaginary triangle. The imaginary triangle is moved back and forth when the swing frame is swung back and forth. The carrier is reciprocated to accommodate the reciprocating movement of the imaginary triangle. Thus, the imaginary triangle can be rotated to a desired coating position so far as the amount of offset between the rolls and the output shafts is within the allowable offset range of the offset shaft couplings.
