An improved slotter wheel mechanism (30) de- signed for use in the formation of box blanks is pro vided which includes a rotatable wheel assembly (32) supporting one or more slotter blades (34); the blades (34) are coupled to the wheel by means (36) permitting shifting of the blades (34) during rotation of the wheel assembly (32) between an extended slotting position and a retracted blank-clearing position. In one embodi- ment, the blades (34) are supported on respective blade holders (70) each having a cam (84) secured thereto. A stationary yoke plate (88) adjacent the wheel assembly (32) supports a pair of inner and outer cam grooves (96, 98) adapted to receive the blade holder cams (84). A shiftable, grooved cam switch (100) is operatively inter posed in the cam arrangement for selectively directing the blade holder cams (84) into one or the other of the cam grooves (96, 98), thereby camming the associated blade holders (70) and blades (34) between their respec- tive positions.
