Abstract
Method for changing the pitch between discrete entities conveyed in succession between a device for feeding the entities at an initial spacing pitch provided between two entities fed in succession and a device for receiving the entities at a final pitch substantially greater than the initial pitch. The method including transporting the discrete entities by a variable pitch feed screw device configured to receive the entities downstream of the device for feeding the entities, the screw including a groove in which the entities are capable of being housed and displaced, so that the pitch between two entities received by the screw is increased downstream of the screw as far as an intermediate pitch; and transferring and gripping the entities at the intermediate pitch by a wheel for changing the pitch, configured to transfer the entities into the receiving device at the final pitch.
