A blade assembly includes a blade support frame, and a plurality of V-shaped blades removably fastened to the blade support frame. The blade support frame has a food flow path extending downstream, and a plurality of blade mounts distributed around the food flow path. Each V-shaped blade has a first end portion connected to one of the blade mounts, a second end portion connected to another of the blade mounts, and an intermediate portion extending from the first end portion to the second end portion into the food flow path. At the first and second end portions of each V-shaped blade, a respective one of the blade mounts overlies both the upstream edge and the downstream edge of the V-shaped blade to inhibit the V-shaped blade from rotating when impacted by food.

The present invention is a cast iron pipe cutter. The cast iron pipe cutter includes a movable upper cutting tool and a rigid lower cutting tool. The upper cutting tool and lower cutting tool includes multiple cutting disc spaced an arc length apart. As the upper cutting tool is advanced downward by a hydraulic press, the cutting discs apply increasing pressure to the outer surface of a cast iron pipe until each cutting discs in the upper cutting tool and the lower cutting tool creates a fracture in the cast iron pipe. The multiple fractures created by the cutting discs amalgamate into a single fracture and the cast iron pipe is cut almost instantaneously.

A food product cutting system can include a food product carrier for carrying food product circumferentially around an axis of rotation, where the food product carrier includes food cutters each having a knife and a corresponding pusher. Each knife is for receiving and engaging with food product, and each pusher is slidably coupled with a knife and movable for pushing food product out of engagement with the food cutter. The food product cutting system can also include a track oriented generally circularly with respect to the food product carrier. The track can be arranged at varying radial distances from the axis of rotation and coupled with followers. Each follower can be connected to a corresponding pusher. In operation, food product moved into the knife of a food cutter and carried around the axis of rotation is incrementally pushed out of engagement with the food cutter by the corresponding pusher.

Knife assemblies adapted for use in slicing machines includes a knife holder having a support surface that defines an outer upper surface of the knife holder and a leading edge of the knife holder. An insert is supported by the knife holder and has leading and trailing ends that each extends along a longitudinal extent of the knife holder, and a longitudinal end between the leading and trailing ends. A knife is at least partly supported by the insert and has a cutting edge that projects beyond the leading end of the insert. The knife is clamped to the knife holder and the insert is secured to the knife holder by at least a first slot defined in the trailing end and/or longitudinal end of the insert, and at least a first locking post that engages the first slot and secures the insert to the knife holder.

An apparatus for emptying bags includes a cutting mechanism, wherein cut bags are separated from the contents therein on a bag support, a bag disposal mechanism including a vacuum unit to deliver the bags to a disposal unit. The cutting mechanism includes first and second cutting devices arranged to cut the bags along at least two cut directions, in relation to a longitudinal direction along which the bags are conveyed from the cutting mechanism, to cut a foldable flap in the material from which the bags are formed so that the flap can fold into openings of the bag support to empty the content through the openings. A related method for emptying bags is also disclosed.
