ABSTRACT:
A holder for rotating cutting knives includes a cylindrical holder including a longitudinal groove and a blade having a cutting edge and an opposed edge separated from the cutting edge by a first contact face. A gib assembly is provided for holding the blade in the groove of the holder, and includes a gib movable within the groove between a blade insertion position and a blade securing position. The gib has a second contact face that engages the first contact face of the blade when the gib is moved to the second position, and one of the first and second contact faces is provided with at least one longitudinal groove and the other of the first and second contact faces includes at least one longitudinal ridge which mates with the groove when the gib is in the second position in order to prevent the blade from slipping out of engagement with the gib means.
