The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

An apparatus and method for forming zig-zag folded logs of web material is provided. The apparatus and method allows for forming logs having different sheet lengths on a same machine. Logs of web material having weakened regions at different locations between folds in the zig-zag folded web are also provided.

A food product slicing apparatus is configured to slice food products into slices. A load assembly pivotally is mounted on a frame and a food product is positioned thereon. A drive assembly on the frame receives the food product from the load assembly and moves the food product relative to the frame. The load assembly can be positioned in at a first, lowered position relative to the drive assembly, a second, partially raised position relative to the drive assembly and a third, fully raised position relative to the drive assembly. The drive assembly engages the food product when the load assembly is in the third, fully raised position.

A food slicing system includes a hub fixedly secured to a drive shaft and configured to rotate with the drive shaft. The hub has a central pilot projection coaxial with the drive shaft, and flat, blade contacting surface surrounding the pilot projection. A counterweight is eccentrically mounted to the hub and rotatable between a first position and an second position relative to the hub. Wherein when the counterweight is in a first position, the counterweight is in axial alignment with pilot projection, and permits the blade to be attached to or removed from the hub via movement of the blade in the axial direction. When the counterweight is in the second position, the counterweight is eccentric to the pilot projection and is offset from the axis of rotation, to provide a predetermined amount of weight offset from the axis of rotation to counterbalance the weight of the blade.

A food product slicing apparatus is provided for slicing food products into slices. A frame mounts a drive assembly, a lower feed roller, a shear bar and a slicing blade. The drive assembly moves the food products onto the lower feed roller. The food product passes over the lower feed roller and through the shear bar for slicing by the slicing blade. At least one upper feed roller is mounted on the shear bar and is adjustable in position relative to the lower feed roller.

A food slicing system having a main frame includes a blade reciprocating assembly, which further includes a support frame, a rotating cutting blade mounted to the support frame, a motor mounted on the support frame, and a support shaft operatively coupled to the main frame at opposite ends thereof. The support shaft is coupled to an upper portion of the support frame and is configured to support the support frame and permit pivotal movement of the support frame. A drive shaft is operatively coupled to the main frame and is rotationally driven by an actuator. A plurality of linkage elements are configured to operatively couple the drive shaft to a lower portion of the support frame, where the linkage elements reciprocally move the blade reciprocating assembly between a slicing position and a clearance position, and where the support frame pivots about the support shaft during the reciprocal movement.

A food product slicing apparatus for slicing food products into slices is provided. A frame mounts a drive assembly which is configured to move the food products relative to the frame, a side strapping assembly which side straps a side of the food product, and a slicing blade configured to slice the food products into slices. The side strapping assembly is mounted to the frame proximate to the drive assembly. The side strapping assembly includes a releasable clamp which couples a blade of the side strapping assembly to the frame. The clamp can be released without the use of tools.

A food slicing includes a forward conveyor assembly located proximal to the blade assembly and a rearward conveyor assembly configured to transport the food product to the forward conveyor assembly. The rearward conveyor assembly is located immediately upstream from the forward conveyor assembly and gap is formed laterally between the forward conveyor assembly and the rearward conveyor assembly, in the longitudinal direction. An upper scanner unit proximal the gap scans an upper surface of the food product while a lower scanner unit located below the forward and rearward conveyor assemblies scans a lower surface of the food product as the food product passes across the gap, to obtain contour information of the lower surface of the food product.
