DEVICE FOR SHARPENING BLADES Russian patent published in 2018 - IPC B24B3/36 B24B3/46 B24D15/08 B26D7/12 

FIELD: machine building.

SUBSTANCE: invention relates to mechanical engineering and can be used for sharpening blades mounted on cutting machines, in particular for the paper rolls production. Device comprises two grinding wheels supported by respective movable supports, adapted to move grinding wheels from a standby or rest configuration in which the grinding wheels are positioned to an active configuration along a predetermined trajectory. Movable supports are adapted to move said grinding wheels along respective arcuate trajectories, such that the contact of each grinding wheel with a respective side of the cutting edge of the blade is progressive when the device passes from the standby rest configuration to the active configuration.

EFFECT: as a result, effective sharpening of the blades during cutting of the products is ensured.
