Abstract

Abstract A brush cleaning apparatus which includes at least one brush cleaning means having a pair of rotary brushes that are arranged in parallel one above the other. Disk-shaped objects are transported one at a time between the brushes so as to be cleaned thereby. A stopper is provided in front of the disk-shaped objects. The stopper selectively blocks movement of the disk-shaped objects and releases the disk-shaped objects for controlled movement of the disk-shaped objects through the cleaning apparatus.
