ABSTRACT:
Apparatus is disclosed by which a number of thin, disc-like wafers are moved in a linear path and fed into such path on a discrete basis from a supply or feeding station. The individual or discrete wafers are moved into engagement with a pair of endless belts which, in effect, define the linear path and are arranged one over the other with the facing portions of the belts being spaced apart by at least the diameter of the wafers to be interposed therebetween. As the wafers are moved through the linear path by the belts, they are moved between pairs of brushes, each of a pair being rotatably mounted on a respective side of the path for engaging and cleaning the surfaces of the wafer, the pairs of brushes extending in the direction of movement of the wafers. The belts and the brushes are coupled to drive means such that the rotary forces applied to the surfaces of the wafers by each pair of brushes is nullified to the extent that rotation of the wafers in one direction and movement along the path by the belts is not inhibited.
