Proposed are a method and a device for consolidation of a number n of items, whose weight varies within predefined limits, in a container to a single unit with a predefined target weight. For this purpose, n−1 portions are combined and the weight of all of the n−1 portions is determined. Then the difference between the target weight of the n portions on the one hand and the weight of the n−1 portions on the other is determined. Ultimately, an nth portion with a precise weight is cut-off from a piece, where the weight equals the weight of the nth portion of the difference. For this purpose, the device is provided with a first and a second insertion station, a scale, a computer, and a portioning and cutting device.
