  • Unit for feeding an ordered succession of products to an unloading station
    Patent number: 6640961
    Abstract: A unit for feeding an ordered succession of products to an unloading station comprises: an arranging device including a first and a second conveyor, each constituting a first and a second conveyor portion on a feed path whose total length is the sum of the two portions that complementarily vary in length relative to each other; a device for feeding the products to the first conveyor in sets; a transfer device located between the conveyor portions, coupled to the conveyors and designed to complementarily vary the lengths of the portions. The transfer device comprises two resilient belts that transfer the products from the first to the second portion. The feed device is cyclically mobile and, consequently, the first conveyor and the transfer device are cyclically mobile according to a law of motion and timing dependent upon the cyclic motion of the feed device.
