The machine includes a feeding path for the logs to be cut and a cutting head arranged along the feeding path. 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 at least a grinding unit, including at least one grinding wheel mounted onto a rotation shaft and co-acting with a side of the disc-shaped cutting blade to grind the cutting edge of the same disc-shaped cutting blade. A controlled approach system is also provided to move the grinding wheel towards the disc-shaped cutting blade.

An electronic pipe cutting system and methods of use are described herein. A drive cutting assembly contains one or more cutting wheels that rotate around a pipe. A drill is used to connect to a main shaft and one or more gears transfer and transform the energy of the drill into optimal motion of the cutting wheels. The present invention provides a low cost, compact and lightweight pipe cutting system in comparison to other electronic pipe cutting system.

The invention relates to a device for slicing food products, in particular a high-performance slicer, comprising a rotor shaft which rotates about a rotational axis during operation and which can be adjusted in an axial manner, in particular in order to carry out blank cuts and/or to adjust cutting gaps; a rotor which is driven by the rotor shaft; a cutting blade which is supported by the rotor, in particular a circular blade which rotates about the rotational axis in a planetary manner and additionally rotates relative to the rotor about a blade axis that runs parallel to the rotational axis in an offset manner; and a rotary drive for the rotor shaft.

A method involves conveying tissue logs in a saw conveyor. The conveyor has independent lane control cutting and variable conveyor flight length. In one aspect of the method a first tissue log is received in a lane of a conveyor. With a first log advancement member, the first tissue log is advanced in the lane of the conveyor for cutting with a tissue log saw. A second tissue log is received in the lane of the conveyor when the first tissue log has advanced sufficiently in the lane to accommodate the second tissue log in the lane. With a second log advancement member, the second tissue log is advanced in the lane of the conveyor for cutting with the tissue log saw independently of the step of advancing the first tissue log in the lane. The conveyor may also have multiple lanes.

A slicing machine for foodstuffs in block form has a slicing blade for the foodstuff in block form and a shaft for receiving the foodstuff. The longitudinal direction of the shaft corresponds to the feed direction of the foodstuff in block form. The shaft has a first shaft region and a second shaft region which are at least partially separated from one another by a slot. At least one offset lies between the two shaft regions. The two shaft regions can be moved relative to one another such that the offset can be reduced by the movement.
