Abstract: The invention is embodied as a unit for grading produce and comprises a transporting device having parallel belts and receptacles which open downwardly and in which produce is arranged, and a weighing station comprising a weighing wheel driven in rotation by a gear motor and a section of which projects into the receptacles so as to carry the produce as it passes through the weighing station. The weighing wheel and the gear motor are supported by a device for weighing the produce. The unit also includes a grading station comprising several stations for ejecting the produce from the transporting device into a device for removing the produce as a function of the weight of the produce.

Abstract: A film of liquid plastic material is formed by surface tension on supports. By a relative displacement, a product and the film are brought into contact with each other, the film deforming under action of the product so as to be progressively applied on and closing onto the product and completely wrapping the product after the product has passed through the supports.
