The invention relates to a method for positioning a shoe of a shoe press / shoe clender in a paper machine. In the method, the position of the shoe (11) of the shoe calender / shoe press is measured and, based on the results of the measurement, the position of the shoe is controlled so as to be as desired in the direction of nip compression. The invention also relates to an arrangment for positioning a shoe of a shoe press / shoe calender in a paper machine, which arrangment comprises a shoe roll (10) or equivalent which includes a shoe (11) and hydraulic cylinders (12) connected thereto for moving the shoe (11). The arrangement comprises further at least two measuring devices (15) for measuring the position of the shoe (11) and means (12) for controlling the position of the shoe (11) based the results obtained by means of the measuring devices so as to be as desired in the direction of nip compression.
L'invention concerne un procédé permettant de positionner le sabot d'une presse à sabot/calandre à sabot dans une machine à papier. Ce procédé consiste à mesurer la position du sabot (11) de la presse à sabot/calandre à sabot et, sur la base des résultats de la mesure, on règle la position du sabot de manière qu'il se trouve, comme prévu, dans la direction de compression dans l'espacement. L'invention concerne également un dispositif permettant de positionner le sabot d'une presse à sabot/calandre à sabot dans une machine à papier. Ce dispositif comporte un rouleau à sabot (10) ou un dispositif analogue qui est constitué d'un sabot (11) et de cylindres hydrauliques (12) reliés au sabot afin de le déplacer. Ce dispositif comporte en outre au moins deux dispositifs de mesure (15) permettant de mesurer la position du sabot (11) et un dispositif (12) permettant de régler la position du sabot (11) sur la base des résultats obtenus à l'aide des dispositifs de mesure, de manière qu'il se trouve, comme prévu, dans la direction de compression dans l'espacement.
