A combination weighing machine structure including a feed hopper and an underlying weigh hopper, in which the weigh hopper has two chambers laterally partitioned side by side and the feed hopper is adapted to move laterally and selectively to above either chamber. The weigh hopper is provided with a weighing unit for producing an electric signal indicative of the weight of product in both chambers and the weighing unit is arranged to provide the weight of product in each chamber for storage by measuring first the weight of product in one chamber when only this chamber is filled, measuring the total weight of product in both chambers when the other chamber is also filled and calculating the difference of both weights.
