The invention relates to an apparatus for separating grain, kernel or cereal from crop having a separating rotor operatively mounted in a rotor housing and having a rotor axis, a separating grate located between the separating rotor and the rotor housing, a plurality of frame portions operatively mounted to the separating grate, profiles operatively connected to the plurality of frame portions, and extending parallel to the rotor axis, and webs are repeatedly bent in a step-like shape and operatively mounted between the profiles and the plurality of frame portions and transverse to the rotor axis forming a sieve area for separating the grain from the crop mat. The separating grate is utilized in a combine harvester, preferably a self-propelled combine harvester. The separating grate has a plurality of frame portions operatively connected to profiles. Webs are operatively mounted between the plurality of frame portions and the profiles. The webs have apertures therein, are repeatedly bent in steps and are inserted and operatively mounted in notches of the profiles forming a sieve area. The sieve area is used to sift, separate or loosen grain, kernel or cereal from the crop with reduced fragmentation and clogging.
