<p>An apparatus and method is claimed with a with receiving zone, for receiving solid material, a transferring zone, for transferring said solid material and optionally a releasing zone for releasing said solid material, e.g. to another moving surface and with a moving endless surface moving in and through said zones, said a moving endless surface has thereto a multitude of primary cavities and secondary cavities receiving said solid material, whereby said primary cavities are connectable/connected to said vacuum system of said transferring zone, and said secondary cavities are not connectable/connected to said vacuum system of said transferring zone, and whereby thus only said primary cavities transfer said solid material e.g. to said further moving surface; and whereby typically both primary and secondary cavities are connectable/ connected to a vacuum system in said receiving zone.</p> |
