Abstract: An assembly of a pellet press and a pellet breaking device mounted on the pellet press, the pellet press being equipped with a cylindrical outer wall that is provided with a series of radial through holes for radially and outwardly pressing the pellets from within the press towards and away from an outer circumferential contour of the pellet press, wherein the breaking device encircles the pellet press at a predefined distance from the outer circumferential contour of the pellet press, and that the plate is equipped with a series of slits providing to the pellets a release-way away from the pellet press, wherein the slits span at least a part of the outer circumferential contour of the pellet press along an area that is provided with the through holes, and wherein the slits are provided in two series with mirror image orientations that are pointing towards each other.

Abstract: A method for use in a sheet feeder having a sheet stacking unit with a bottom plate to support a sheet bundle in which air is blown against a side edge of the sheet bundle near the topmost sheets of the bundle, thereby lifting these sheets from the bundle, and separating the uppermost sheet from the bundle, and conveying this sheet away from the bundle, wherein the lifting of the sheets when the bundle is nearly depleted is assisted by forcing an element situated underneath the bundle to push against the bundle solely when air is blown against the side edge of the bundle. A sheet feeder suitable for applying the present method and an imaging apparatus for incorporating the sheet feeder is also provided.
