Abstract: A check-weighing apparatus is provided wherein a conveyor feeds articles in a discrete manner onto a weighing device, the feeding of the articles being terminated, and the articles being removed from the weighing device, when a predetermined weight is attained. A receptacle receives a batch of articles from the conveyor and when a predetermined batch quantity is attained within the receptacle which is less than the predetermined weight referred to, the batch is released onto the weighing device. The conveyor then tops up the batch to the predetermined weight.
