In a machine for topping and tailling onions, onions 7 are carried on a slowly rotating plate 1, having perforations 2, along a spiral path defined by a wall 8 suspended from a supporting structure 9, the onions 7 being held on the plate 1 and retarded in relation thereto by flexible holding members 9, preferably rubber sheets, suspended from the supporting structure 9, the holding members 9 being provided with projections 13 extending substantially horizontally towards the advancing onions 7, and the protruding parts of the onions being removed by high speed rotary knives 4 beneath the plate 1 when these protruding parts extend through the slit-like perforations 2. An eccentric 16 mounted on the drive shaft 6 for the knives 4 causes a circular vibratory movement of the supporting structure 9, means being provided to prevent rotation of this structure 9. The rubber holding members 9 have an enlarged upper edge 14 which is releasably engaged by sliding in a channel 15 carried by the supporting structure.
