摘要： An apparatus is provided for conditioning a fabric being advanced in a machine direction in a papermaking machine. The fabric has an outer side adapted to engage a paper web and an opposing inner side. Such an apparatus comprises a fluid-emitting device configured to wet the fabric with a fluid so as to clean the fabric. An arcuate member disposed downstream of the fluid-emitting device is configured to engage the outer side of the fabric. More particularly, the arcuate member is configured to have the fabric wrapped at least partially thereabout such that the advancing fabric is centrifugally dewatered. Associated systems and methods are also provided.

摘要： A multi-reel apparatus for use in a drying section of a papermaking machine allows a web to be continuously wound without interruption. The apparatus includes a web support and a pair of vertically stacked reeling stations located along an inclined portion of the web support. Each reeling station has at least one reeling device operable to hold and rotatably drive a core onto which the web can wound to form a roll. Each reeling device is further operable to move the core into engagement with the web on the web support to initiate winding of the web onto the core, and to move the core away from the web support when the roll is fully wound. Winding is alternated between reeling devices, allowing the completed roll to be removed and a new core to be loaded at one reeling station while the other reeling station continues in full winding operation.

摘要： A winding apparatus for winding a paper web (1), comprising a reel spool (3) onto which the web is wound to form a paper roll (4), a support member (2) forming a nip (5) with the paper roll, and an actuator (24) mounted at the support member or reel spool to control the distance therebetween. According to the invention the apparatus has a measuring and controlling equipment comprising a light-emitting member (6) to illuminate the paper roll by light providing a line (7) on the cylindrical surface (8) of the paper roll, a receptive system arranged to depict the line, and a control unit (10) connected to the receptive system and arranged to analyse the depicted line in order to calculate the distance between the paper roll and the support member and send a position-correcting signal to the actuator when the distance calculated deviates from a predetermined distance. The invention also relates to such a measuring and controlling equipment and a method for controlling the distance between the paper roll and the support member.

摘要： A device is provided for dewatering a fabric in which the fabric is used in a papermaking process that exposes it to water before it is directed to the fabric dewatering device. The fabric dewatering device includes leading and trailing guide rolls about which the fabric is partially wrapped to form a loop portion. The loop portion is suspended between the leading and trailing guide rolls and includes a trough portion with a relatively small diameter that is positioned below the axes of the guide rolls. Running the fabric through the trough portion at high speeds exposes the water trapped therein to high centrifugal forces. The centrifugal forces expel the water from the fabric. The geometry and positioning of the trough portion is maintained either through a difference in fabric speed maintained by the leading and trailing nips or by the use of a rider roll positioned within the loop. A non-contact sensor in proximity to the trough portion senses the position of the trough portion and provides feedback to a controller which controls the motion of the rolls.

摘要： The inventive idea is to make the rotating elements or rolls in a tissue papermaking machine with a reduced weight comparing to the conventional rolls made of steel. In this manner the rolls create less vibrations and allow sufficiently increase of the operation speed and productivity of the entire machine, or reduce the machine dimension for a given operation speed comparing to the conventional solutions. The invention is applicable to rebuilds of the existing machines and for new high-speed installations.

摘要： A device for protecting a spraying equipment (8) and its surroundings in a paper or board machine, for applying a treatment medium onto a moving surface (3), comprises a protecting cover (11) having a space (12), which forms a single chamber in which the spraying equipment is located and which is open towards the moving surface in connection with an application zone, and two wall elements (13, 14) which extend cross to the machine direction on either side of the application zone, and define machine-wide gaps (24; 40 and 25; 26; 41, respectively) between themselves and the moving surface. According to the invention, the protecting cover has a sealing arrangement arranged in connection with said gaps for restricting passage of air and contaminations through the gaps in a controlled manner; a system for a controlled supply of capture air for capturing contaminations occurring within the space; and an evacuating system for a controlled, continuous evacuation of the capture air with contaminations from the chamber. The invention also relates to a method of protecting such a spraying equipment and its surroundings while using such a device.

摘要： A property of a paper web is measured using one or more reflectance measurement sensors emitting measuring beams onto the web and receiving the beams reflected from the web, from which the web property is deduced. The web is supported on a web support during the measurement, such as on a passive or active airfoil or fabric. One or more measurement sensor(s) can be integrated within an active airfoil, and can comprise a plurality of optical fibers having sensing ends arranged in the airfoil such that the sensing ends of the fibers face the moving paper web through one or more apertures in a web-supporting panel of the airfoil. Alternatively, a traversing sensor can be mounted within the airfoil. Other embodiments include a reflectance sensor mounted adjacent an airfoil or other web support such as a through-air drying fabric or a support belt for the web.
