Element rotating sieve, which is designed as a star sieve, wherein the star sieve flexible fingers resiliently have a radial extension and an axial extension, wherein in or on at least one finger (3; 30; 31; 41) is arranged one piece of reinforcement, the radial extent (c) of the piece of reinforcement (7; 32, 33; 37) greater than the axial extent (d) of the piece of reinforcement (7; 32, 33; 37), and presenting the piece of reinforcement (7; 32, 33; 37) a maximum width, which corresponds to the width of the finger (3; 30, 31; 45), and that the radial extent (f) of the finger (3; 30, 31; 45) is less than the radial extent (c) of the reinforcing part (7; 32, 33; 37)
