The invention relates to a cutting blade, in particular to a scythe-like blade or to a spiral blade, for an apparatus for slicing food products, in particular for a high-speed slicer, the cutting blade rotating about an axis of rotation during a cutting operation, having a radially outer peripheral edge which acts as a blade edge and which has a curved extent about the axis of rotation; and having a plurality of cutting teeth which are arranged distributed following one another along the peripheral edge, wherein each cutting tooth has a blade edge which comprises a cutting surface and a cutting edge radially outwardly bounding the cutting surface; wherein each cutting surface extends inclined with respect to a spanned plane perpendicular to the axis of rotation and/or with respect to a cutting plane; and wherein the inclination of the cutting surfaces varies along the peripheral edge.

A slicing machine for slicing at least one product caliber into slices and for producing portions from the slices, includes a cutting unit with a blade, in particular a rotatable blade that is movable in a cutting plane, for cutting slices from the at least one product caliber, a feed unit for feeding the product calibers to the cutting unit along a feed direction, and a gripper unit with at least one gripper which is movable along the feed direction. The gripper unit comprises a claw drive unit by which gripper claws of the at least one gripper are displaceable between an engagement position in which the gripper claws hold the product caliber and a release position in which the gripper claws do not hold the product caliber. Furthermore, the claw drive unit is configured as an electromagnetically actuated claw drive unit.

There is provided a cutting blade apparatus including: cutting blade units including a plurality of cutting blades arranged on a flat surface; and a base unit configured to support the plurality of cutting blade units overlapping one another, the cutting blade apparatus being configured to perform cutting operation by driving at least one of the cutting blade units. A cutting space formed for each of the cutting blades of one cutting blade unit is opened/closed by a cutting blade of the other cutting blade unit to perform the cutting operation. A timing at which one cutting space is opened/closed is different from a timing at which another cutting space is opened/closed.
