摘要：
An improved slotter wheel mechanism (30) designed for use in the formation of box blanks is provided 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. A cam assembly (406) presents a shiftable cam portion (424) that can be shifted to select a blade extended or retracted position for blade sections (304, 306, and 326) which are interconnected by a respective pivot couplings (332 and 334). The assembly (406) further includes a locking link assembly (448) for locking the blade holder (438) and thereby the blades (442 and 448a, 440b) in the selected position during rotation through the bottom portion of the arc of travel.
