Abstract

For a weight controlled building up of batches of foodstuff pieces, the pieces are supplied serially with mutual spacing and are weighed-in on a dynamic weigher using a 'single weighing algorithm'. Quite similar weighers are known operating for 'summation or flow weighing', which does not require the supplied pieces to be supplied one by one while making use of a special algorithm. With the invention these technics are combined with the aim of handling an unorderly supply flow, in which there are both separated and non-separated pieces, in that by means of a detector it is determined whether the pieces are sufficiently separated for being 'single weighed' for batching purposes, while the pieces will otherwise be flow weighed e.g. for the formation of large batches. One and same weigher may be used in both instances, inasfar as based on the said detection it is currently decided whether the weighing signal should be processed in accordance with one algorithm or the other, all according to what is most suitable in the actual operational situations.
