ABSTRACT:
A disk to be coated on both sides in rotatively supported within an annular housing of a larger internal diameter. Means traverse and coat each side of the rotating disk. The inner housing wall is disposed transversely to the disk and has an annular slot operatively associated with the disk whereby excess coating material is spun off the disk and into the housing. The housing is radially of a triangular cross-section, the apex offset from said disk whereby said spun off material strikes an inclined internal wall surface of the housing. Means orbit a plurality of such disks about a central axis and through a plurality of movable treating stations.
