A cleaning mechanism for use with a closed loop conveyor belt supported in continuous traversing fashion. The mechanism includes a housing for supporting the belt, a frame mounted to the housing proximate to the belt. A drive shaft extends between spaced apart locations of the frame and includes a pair of head sprockets adapted for supporting the belt at a selected location. A motor is engaged to an input end of the drive shaft. A counter weighted comb element is pivotally secured to the frame, an upper angled combed edge of the comb element arrayed in spatial non-contacting fashion with a traversing exterior of the belt for capturing elongated shaving debris suspended from the belt. A slave shaft extends between additional spaced apart location of the frame and which is rotated via a linkage with the drive shaft. Pluralities of bristles extend from the slave shaft in a cylindrical arrangement such that selected width extending portions of the bristles are arranged in successive contact with the belt upon rotation of the slave shaft in order to scrub the belt.
