摘要： An apparatus and method for tensioning a fabric in a paper machine, such as a press felt, a drying wire, or an equivalent fabric, including a tensioning roll arranged inside a loop of the fabric. Bearing supports of the roll are fixed, at the driving side and at the operating side of the machine, to sledges. These sledges are displaced by a motor, synchronously in relation to one another, so as to tighten the fabric that runs over the tensioning roll to a certain tension. The sledges are arranged in connection with the frame part of the machine on linear guides, which can be loaded in different directions transverse to the direction of movement of the sledges. In view of displacing the sledges, shafts operated by a motor are journalled on the sledges. The shafts are interconnected by a synchronization shaft between the driving side and the operating side.

摘要： A paper machine dryer group has a plurality of rolls, including a guide roll and a tension roll, and a carrier belt traveling over the rolls and forming a continuous loop. The guide roll can be displaced to a location parallel to its axis as well as at an angle to the direction of movement of the carrier belt. The guide roll and the tension roll are coupled to each other in such a way that, when the guide roll is displaced, the tension roll is simultaneously displaced in such a direction and to such an extent that the carrier belt tension remains at least approximately constant.

摘要： A dryer felt tension indicator apparatus is disclosed for indicating a value which is proportional to a tension applied between a frame and a stretcher roll for guiding a dryer felt. The value is proportional to a tension of the dryer felt. The apparatus includes a carriage for rotatably supporting the stretcher roll. A wheel is rotatably secured to the carriage and a tensioner having a first and a second extremity cooperates with and extends around the wheel such that the wheel is disposed between the first and the second extremity of the tensioner. A tension indicator has a first and a second end. The first end of the tension indicator is anchored to the frame. The second end of the tension indicator is secured to the first extremity of the tensioner such that in use of the apparatus, when the tension is applied to the tensioner between the wheel and the second extremity of the tensioner, the carriage and the stretcher roll rotatably supported thereon is moved relative to the frame for tensioning the dryer felt. The tension indicator indicates the value which is proportional to the tension of the dryer felt.

摘要： A paper or board machine has a fabric (10) that is adapted mobile as well as rolls (11, 11′) arranged to support the fabric (10). The fabric (10) is tensioned by changing the position of one roll (11′) of the rolls (11, 11′). Correspondingly, the fabric (10) is guided by changing the alignment of one roll (11′) of the said rolls (11, 11′). Surprisingly the fabric (10) is both tensioned and guided by changing the alignment and position of only one and the same roll (11′). In addition, the wrap angle of the fabric (10) at this roll (11′) is set higher than 30°.

摘要： A device (1) serves to regulate the tension of a running web (2). The Web (2) is deflected on rollers (6, 7, 8, 9, 15) of which one is designed as a force measuring roller (15) and tension regulating roller (18). This roller (15, 18) is provided with at least one force sensor (16) that determines the bearing force (F). In addition, this roller (15, 18) is adjustably held by an actuating drive (13) in order to be able to adjust the tension of the web (2). The actuating drive (13) is in an operative connection with a regulating device (21) influenced by a correction device (17). This correction device (17) determines the web tension from the bearing force (F) measured by the force sensor (16) and from the looping, that changes with the position of the tension regulating roller (18), and transmits this web tension as an actual value to the regulating device (21).

摘要： In an apparatus wherein an endless band is trained over a stationary guide roll and a stretching roll, and a nut-and-spindle mechanism at the ends of the stretching roll can displace the stretching roll in a plane defined by the axes of the rolls when the band is centered on the rolls, the band is automatically centered by two hydraulic double-acting cylinder-piston units. The first unit displaces either end of the stretching roll in the plane and the second unit simultaneously displaces one end in a plane perpendicular thereto. This displacement is effected in response to a control signal from a sensor adjacent each side edge of the band and tripped when the side edge moves into contact therewith as the band moves out of its centered position. The control signal operates a three-way solenoid valve in a hydraulic control circuit for the cylinder-piston units.

摘要： A conveying installation has least one endless conveyor belt guided via a plurality of rollers along a leading belt run for conveying material or products and a returning belt run, particularly for manufacturing a paper web with a wire belt or felt belt. At least one of the rollers has an adjustable mounting for adjusting and correcting a direction of movement of the conveyor belt. A tensioning unit for detecting and controlling a tension of the conveyor belt has a pressure-measuring apparatus disposed at the adjustable mounting. A movement correction unit for detecting deviations of a direction of movement of the conveyor belt from a correct movement and for correcting the movement includes a sensor that is disposed to monitor a lateral periphery of the conveyor belt. A sensor output of the sensor is used for adjusting the adjustable mounting of the one of the rollers.
