Abstract

In order to provide a suitable packaging system, mesh pieces are deposited across the width of a moving run of flexible wrapping material and are deposited in longitudinally overlapping relationship along the length of the wrapping material, by feeding the mesh pieces on a belt which moves more quickly than the wrapping material; the mesh pieces are ejected from the end of the belt onto the wrapping material. The direction of movement of the wrapping material is inclined downwards so that the trailing ends of the mesh pieces contact the wrapping material before the leading ends contact the preceding mesh piece. The wrapping material, with the mesh pieces on it, is then rolled up under tension into a spiral bale so that the overlapping edges curl down and prevent the mesh pieces slipping out.
