ABSTRACT:
A lay-down bar structure having one or more resilient polyurethane flaps supported by a rigid bar so that the edges of the flaps are offset slightly from the periphery of the primary cleaning drum of a cotton cleaner. The flaps are slotted and can be adjusted relative to the drum periphery. The flaps can also be stacked, and the number of flaps can be increased or decreased for a corresponding change in cleaner aggressiveness. The resilient flaps flex to allow large foreign objects to pass between the lay-down bar and the drum to thereby reduce drum damage, shock loads and plugging problems.
