Counterweight for reciprocating conditioning roll

摘要

A counterweight mechanism for use in conjunction with a conditioning apparatus having a reciprocating conditioning roll is disclosed wherein the counterweight is mounted within the hollow core of the reciprocating conditioning roll and connected to an ocillating mechanism to effect a transverse reciprocating movement thereof in opposition to the reciprocating movement of the conditiioning roll. The ocillating mechanism can include a cam mechanism operatively associated with the counterweight and housed internally of the conditioning roll to effect a linearly reciprocal movement of the counterweight in response to the rotation of the reciprocating conditioning roll. The counterweight can be slidably mounted on a non-circular shaft corresponding to the reciprocating conditioning roll so that the counterweight is rotatable with the conditioning roll yet is linearly moveable relative thereto.
