Patent number: 7614182Abstract: A method for separating a lump piece of rosette plants. The method includes the steps of gripping a rosette plant and positioning it parallel to a longitudinal axis of an elongated holder which has a longitudinal opening at least along the longitudinal axis; introducing a part of the lump piece of the rosette plant into the holder via the mentioned longitudinal opening; cutting off the lump piece along a cutting plane parallel to the longitudinal axis, while closing the longitudinal opening, such that the introduced part of the lump piece is enclosed in the holder; and removing the enclosed cut-off part of the lump piece from the holder. The method includes the further step of cutting off a part of the rosette plant enclosed in the holder along a second cutting plane.Type: GrantFiled: September 15, 2003Date of Patent: November 10, 2009Assignee: Nederlandse Organisatie voor toegeast- Natuurwetenschappelijk Onderzoek TNOInventors: Michiel Peter Oderwald, Justus Laurens Herder, Roland André Pieter Higler
