Apparatus (10) for trimming a blow molding (12) includes a rotary trimming assembly (16) rotatively mounted and driven on a trimmer head (14). The trimming assembly (16) includes a tube (18) of a rotary member (46) aligned with the blow molding such that operation of an actuating mechanism (20) provides cam actuated movement of a knife holder (48) to perform the trimming which allows the trimmed off blow molding portion to move through the tube (18) away from the trimmed blow molding in preparation for the next trimming cycle. A vacuum source (36) draws a vacuum within a conduit (34) connected to the tube (18) to provide the movement of the trimmed off blow molding portion away from the trimmer head.
