A whetting device is for a slicer. The whetting device has: a whetstone that sharpens a circular blade of the slicer; a hone that deburrs the circular blade; a handle that moves the whetstone or the hone toward the circular blade; and a mount for fastening to a stop plate of the slicer. The mount has an insertion apparatus for being form-fittingly inserted into the stop plate. The mount having a U-shaped plate receptacle, which has a gap for introducing the stop plate into the gap in when the whetting device is pushed onto the stop plate. The insertion apparatus has a lug for engaging in an recess in the stop plate, or the stop plate has the lug for engaging in the recess in the insertion apparatus.

A cutting apparatus includes a chuck table for holding a workpiece thereon, and a cutting unit for cutting the workpiece held on the chuck table. The cutting unit includes a spindle, a mount base fixed to a distal end of the spindle and having an annular coupling face extending around an axis of the spindle and external threads on a distal end portion of the mount base, a ring-shaped ring mount coupled to the coupling face of the mount base and having an annular support surface supporting a surface of an annular base of a hub blade, a coupling mechanism coupling the ring mount to the coupling face of the mount base, and a nut threaded over the external threads of the mount base.

The machine includes a feed channel of a product to be cut and members for feeding the product along the feed channel. A cutting blade is provided to cut the products into articles according to cutting planes orthogonal to a longitudinal direction of the products and a sharpening unit is provided to sharpen the cutting blade. The machine further includes an adjustment system that receives in input at least one information on the operation of the cutting machine and provides, in response to the information, an adjustment command of the cutting machine.

A cutting machine for the transversal cutting of paper material logs, including: a structure on which are moved the logs; a cutting unit including a blade; at least one sharpening unit with two grinding wheels; a positioning device for positioning the grinding wheels with respect to the blade. The positioning device includes: a primary carriage and two secondary carriages supported by the primary carriage; a sensor for detecting the radius of the blade and configured to stop the primary carriage when the grinding wheels are arranged with the respective axes at a given distance from the axis of the blade. In a second phase of positioning the grinding wheels, the secondary carriages are controlled so as to bring the abrasive side of the wheels into contact with the blade.

A log saw for cutting convolutely wound logs of web material is disclosed. The log saw includes a cutting blade operating in a cutting plane, a log saw clamp for the retention of a convolutely wound log of web material such that the convolutely wound log of web material extends in a log advancing path through to the cutting plane, and controls connected to the clamping device.

A spatula edge trimming apparatus for re-edging a spatula includes a base housing with the front side having a spatula receptacle slot extending through to the cavity. The bottom side has a drop aperture extending through to the cavity. The spatula receptacle slot is configured to receive a spatula. A cutter is coupled to the base housing within the cavity and is configured to cut an edge of the spatula. A drive is coupled to the top side of the base housing and is in operational communication with the cutter. A plurality of controls is coupled to the base housing and is in operational communication with the drive. A power source is coupled to the housing. The power source is in operational communication with, and provides power to, each of the drive and the plurality of controls.

Dynamic regulation of contact pressures in a blade sharpening system is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply dynamic cushioning and processor-controlled contact pressure between the grinding wheels and the cutting blade during sharpening. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components.
