Abstract

A product metering apparatus (10) includes a first product conveyance mechanism (12) conveying product in a continuous stream. A platform (42) supports product and is movable along a closed path between a loading position adjacent to the first product conveyance mechanism (12) and a transfer position adjacent to an output in the form of a second product conveyance mechanism (22) spaced from the first product conveyance mechanism (12) in the conveying direction. The platform (42) in the loading position receives the product in the continuous stream from the first product conveyance mechanism (12) and is then accelerated to a speed greater than the first product conveyance mechanism (12) creating a gap between the product supported on the platform (42) and the product remaining in the continuous stream on the first product conveyance mechanism (12). A sweep bar (52ba) is inserted into the gap and abuts with the product on the platform (42) for assisting transfer of the product on the platform (42) to the output.
