This invention relates to a winding machine, and in particular to a winding machine for corrugated paper, and to packaging pieces produced by the machine. There is provided a winding machine for corrugated paper which includes a mandrel (30) having a rotation axis and an ejector (50) movable substantially parallel to the said rotation axis characterised in that the ejector has an ejector arm (52), and in that means are provided to move the ejector arm (52) along a first path in one direction and along a second path spaced from the first path in the opposite direction. There is also provided a method of preparing a corrugated paper roll ready for pressing into a packaging piece which includes the steps of rotating a mandrel (30) about an axis, guiding corrugated paper (10) to be wound around the mandrel into a roll, stopping the mandrel rotation, moving an ejector arm (52) along a first axial path in one direction to remove the wound roll from the mandrel, and moving the ejector arm along a second axial path spaced from the first path in the opposite direction concurrent with the guiding of fresh corrugated paper for winding about the mandrel. |
