Abstract (en)
The invention concerns an adjusting device for the top lip beam of the headbox of a paper machine, board machine, or wet-lap pulp machine, by whose means the position of the top lip beam (13) is changed for regulation of the height (h) and position (s) of the discharge opening (15). The top lip beam (13) is included in a headbox in whose discharge duct (16) there is a perforated roll (14) as an equalizing member, and between which perforated roll (14) and the top lip beam (13) of the headbox there is a gap (C). The adjusting device comprises adjusting members (54,56) for changing the position of the top lip beam (13) and adjusting members for regulating the gap (C) between the top lip beam (13) and the perforated roll (14). The members for adjusting the gap (C) between the top lip beam (13) and the perforated roll (14) consist of a mobile, rigid partition wall (30), which is by one end linked (32) with the top lip beam (13) and by the other end linked (31) with a part (43) which is arranged mobile in the vertical direction (V) in relation to the stationary front wall (40). The partition wall (30) closes the opening between the stationary front wall (40) and the top lip beam (13). <IMAGE>
