  • Patent number: 5320033
    Abstract: Apparatus for top and tailing vegetables, for example carrots, comprises an endless flexible plastics material belt formed of inter-linked transverse links between which a drive wheel may rest. The belt is divided into compartments by interspaced modified links having upstanding molded walls over most of the width of the belt. The belt tilts from side to side on a wide support surface to tilt vegetables first one way and then the other. Knives operate in margins of the belt free of upstanding walls on vegetables which have been tilted towards them. Sidewalls for the belt which stop vegetables falling off it are absent in the region of the knives to allow detritus to fall easily away.
