The rotatable cylinder (1) is pushed over a surface which is partly covered with leaf-form material. It has pointed spikes (t) which in a rotation position penetrate a transport device (2) which runs around the cylinder. In this rotation position the leaf-form material is fastened onto the spike units and in another rotation position where the spike units are separated from the surface of the transport device the collected material is separated from the cylinder spike units for transport to a collecting container (4). |
