Abstract

The invention concerns a profiling arrangement for the flow in the head box of a paper machine and/or board machine, which consists of a profiling plate 30 which is connected to the upper lip wall 14b and/or the lower lip wall 14a of the head box's lip canal(s) 24, and of a series of profiling devices 31 which are coupled to same. The series of profiling devices comprises a large group of profiling devices 31-1, 31-2...31-N which are placed one after another in the transverse direction, the devices being ideally identical to each other and placed ideally at equal intervals in the transverse direction over the whole width of the head box. The profiling devices are arranged to be regulated by a control system 35. With the series 31-1, 31-2...31-N of profiling devices in the profiling arrangement, it is possible to bring about a wave form in the profiling plate 30 in the paper machine's transverse direction, which will effect corresponding differences in the transverse velocity profile of the pulp-suspension flow in the lip canal 24. <IMAGE>
