A belt assembly for moving a web from a press section (1) of a paper- or board-making machine to a dryer section (3) of the machine, comprises a combination of a first press roll (11) adapted to be arranged at the press section (1), and a stretcher/guiding roll (51) which is arranged between the press section (1) and the dryer section (3). A heat conductive metal belt (5) that forms an endless loop and that is impervious to fluids goes over the first press roll (11) and the stretcher/guiding roll (51), so as to take over a web at the press section (1) and to move the web to the dryer section (3). A guide roll proportional position control is adapted to control the position of the metal belt (5) between the edges of the stretcher/guiding roll (51).

| The invention relates to an arrangement for handling a paper, cardboard, tissue or other fibrous-material web (1) in a machine for producing and/or finishing the same, with an endlessly circulating belt (2) of high flexural rigidity, which wraps around a rotatably mounted control roller (3) with an angle of wrap (5), wherein at least one end of the control roller (3) is displaceably mounted along an adjusting zone (7) for setting the belt tension. In this case, the running of the belt is to be improved and the lateral stress of the belt (2) is to be minimized by the angle of wrap (5) lying between 90 and 180° and the adjusting direction of the control roller (3) lying approximately perpendicular to the bisector (4) of the angle of wrap (5). | ||||||

Eine Vorrichtung (1) dient zum Regeln der Spannkraft einer laufenden Bahn (2). Die Bahn (2) wird dabei an Walzen (6, 7, 8 , 9, 15) umgelenkt, von denen eine als Kraftmeßwalze (15) und Spannkraftregelwalze (18) ausgebildet ist. Diese Walze (15, 18) ist mit mindestens einem Kraftsensor (16) ausgerüstet, der die Lagerkraft (F) ermittelt. Außerdem ist diese Walze (15, 18) durch einen Stellantrieb (13) verstellbar gehalten, um die Spannkraft der Bahn (2) einstellen zu können. Der Stellantrieb (13) steht mit einer Regeleinrichtung (21) in Wirkverbindung, die von einer Korrekturvorrichtung (17) beeinflußt ist. Diese Korrekturvorrichtung (17) ermittelt aus der vom Kraftsensor (16) gemessenen Lagerkraft (F) und der sich mit der Lage der Spannkraftregelwalze (18) ändernden Umschlingung die Bahnspannung und gibt diese als Ist-Wert an die Regeleinrichtung (21) weiter. |

The tensioning apparatus comprises a tensioning roll (30) fitted inside the loop of the fabric, the bearing supports (35a,35b) of said roll (30) being fixed, at the driving side and at the operating side of the machine, to sledges (40a,40b). These sledges (40a, 40b) are arranged to be displaceable by means of a motor (37), synchronously in relation to one another, so as to tighten the fabric (10,20) that runs over the tensioning roll (30) to a certain tension (T). Said sledges (40a,40b) are fitted in connection with the frame part (24;130) of the machine on linear guides (42,44), which can be loaded in different directions transverse to the direction (B) of movement of the sledges (40a,40b). In view of displacing the sledges (40a,40b), shafts (51a,51b) operated by a motor (37) are journalled on the sledges, said shafts (51a,51b) being interconnected by means of a synchronization shaft (36) between the driving side (KP) and the operating side (HP). |
