A grinding- and polishing tool in combination, comprising a stave which has an edge-treatment side comprising a primary treatment area covering a part of its length, and which in the length direction of the stave is followed by an adjoining secondary treatment area covering another part of the length of the stave. The treatment areas are oriented at intersecting planes such that an intermediate angle between adjoining primary and secondary treatment areas is other than 180°. Also disclosed are a tool assembly, an attachment for a food slicer machine, and a method, all of which are unique implementations of the combined grinding- and polishing tool.

A whetting device for a slicer has a whetstone for sharpening a circular blade of the slicer; a hone for deburring the blade; a handle for moving the whetstone or hone toward the blade; a mount fastenable to a stop plate of the slicer, having an insertion apparatus for form-fittingly insertion into the stop plate, a U-shaped plate receptacle which has a gap for introducing the stop plate into the gap when the whetting device is pushed onto the stop plate; a receptacle for engaging around an end of the blade guard ring when the stop plate is a predetermined distance from the circular in the direction of rotation of the blade, and not to engage when shorter than that distance between; and a frame covering a cutting edge of the circular blade and for pivoting the whetting device into a working position.

The pizza cutter cleaning, storage, and isolation device disclosed herein may allow a user to store and clean pizza cutters between uses, while also isolating each pizza cutter intended for specific consumers. Such a device may implement a cartridge system, one or more of which may be installed in a main body, into which a single pizza cutter may be placed. The cartridge may be designed to isolate and clean the pizza cutter installed therein, and the pizza cutters themselves may be color-coded, or the cartridges may be color-coded, so as to prevent cross-contamination of the cutters, the pizzas, or the debris picked up when cutting a pizza. The cartridges may further implement a sanitizing bath into which a pizza cutter head may be suspended, or may implement a catch tank for waste debris. The device may further comprise a blade sharpener for additional functionality.

A cutting machine for the transversal cutting of logs of paper material, including a cutting unit, at least one sharpening unit with two grinding wheels and a device for positioning the grinding wheels. The device includes a primary carriage and two secondary carriages. The primary carriage has a surface arranged at a predetermined distance from the plane of the blade and forming a surface for controlling the run of the secondary carriages. In a first step of positioning the grinding wheels, the secondary carriages bring the abrasive side of the grinding wheels into contact with the surface. In a second step, the secondary carriages bring the abrasive side of the grinding wheels to the plane. In a third step, the primary actuators move the primary carriage until the abrasive side of the grinding wheels contacts the blade.

“A system controls the quality of products in output from a cutting machine, for instance, a log saw that has at least one cutting disc and a sharpening wheel. The control system comprises a PLC controller suitable for controlling the cutting and sharpening process and an inspection system suitable for scanning at a specific time instant, a set of quality values of a roll in output from the cutting machine. A processing unit receives the set of quality values and sends to the PLC controller a command aimed at performing an action consisting of increasing or decreasing one of the following parameters: sharpening time, sharpening frequency, and differential speed between the wheel and the disc, based on the comparison between the set of quality values and a reference quality value, and the action carried out at the previous time instant”.

A tool for steeling a knife includes a frame and first and second steeling components. Each of the components is shiftably mounted relative to the frame for movement between a first position and a second position. The steeling components cooperatively define a knife interface configured to engage and thereby steel the knife. The steeling components are resiliently biased into the first position, with the knife interface moving as the steeling components shift between the first and second positions.
