Open the CIPO recordAbstract From the Canadian patent
This invention pertains to a method to batch-weigh a continuous flow of material. The material flows into a holding container which cyclically drops a load into a weighing container and then continues to receive the flow of material. Before the holding container is again filled, the load in the weighing container is weighed, emptied and, if necessary again weighed to, measure tare weight. The weighing container is then ready to receive another load from the holding container. The material emptied from the weighing container drops into a hopper from whence it continues to flow, as upon a conveyor belt.
