Abstract: An apparatus for removing flexible material from rotating equipment includes a cutter assembly integrated into the rotating equipment. The cutter assembly includes a cutter shaft, a cutter blade coupled to the cutter shaft, and a movement mechanism configured to move the cutter assembly along an axis of the rotating equipment to cut accumulated material from the rotating equipment.

Abstract: A system for perforating containers may have a first rotor assembly with a first set of rotors arranged at least partway along a first shaft, and a second rotor assembly with a second set of rotors arranged along a second shaft. The system may further have a frame that rotatably supports the first rotor assembly and the second rotor assembly in a parallel arrangement such that the first set of rotors interdigitates with the second set of rotors. Each rotor of the first set of rotors and the second set of rotors may have a hub, and one or more lobes extending outward from the hub, each of which is shaped such that, during rotation of the first rotor assembly and the second rotor assembly, the lobes perforate the containers as the containers pass between the first rotor assembly and the second rotor assembly.
