The proposed multilayer head box for a paper machine or similar is constructed so that it can produce a wide jet consisting of at least three individual jets (5, 5', 5'') The individual jets are fed through separate channels (3, 3'', 3'') and emitted out of the head box and subsequently combine to form a single wide jet. The individual channels are so constructed that further outer lying jets can be diverted sufficiently after having been emitted out of their respective channel, so that they meet the respective further inner lying partial stream at a very slight angle. The problem of separation when the partial streams are diverted as well as that of undesired lateral mixing when the partial streams are combined are thereby prevented.
