FIELD: measuring equipment. SUBSTANCE: data collection on the sensor shaft and the conjugated shaft forming the contact zone includes the generation of an appropriate sensor signal by each of the sensors, located in places spaced along the axis of the sensor shaft, with each corresponding sensor signal being generated, when each sensor enters the contact zone area between the sensor shaft and the conjugated shaft during each rotation of the sensor shaft, and receiving the generated signal. After receiving the signal, the processor: a) determines which specific sensor generates this signal, b) determines, on the basis of the angular position of the conjugated shaft relative to the reference position, which of a number of tracking segments associated with the conjugated shaft is encountered, in fact, simultaneously with the sensor entering the contact zone area, and c) stores the corresponding sensor signal to associate this signal with one specific tracking segment. EFFECT: device, allowing data collection on the sensor shaft and the conjugated shaft, is proposed. 26 cl, 17 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 654 676 C1 (51) МПК D21F 3/08 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК D21F 3/08 (2006.01) (21)(22) Заявка: 2016141839, 01.05.2015 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Интернэшнл Пэйпа Кампани (US) Дата регистрации: 21.05.2018 (56) Список документов, цитированных в отчете о поиске: US 9097595 B2, 04.08.2015.

MOLDING COVER FOR A PAPER MACHINE.

Press roll, in particular for paper machines

Press roll with a tubular cylinder, featuring on each of its two ends a roll cover with a journal, specifically for use in a roll press consisting of the press roll and a backing roll with controlled deflection, for the treatment of web type material such as a paper web or the like. The inside surface of the tubular cylinder is so shaped across the web width that the shape of the flex line of the tubular cylinder will approximate during operation the flex line of the roll shell of the backing roll. This yields a press roll having a relatively thin-walled tubular cylinder which is lightweight. Nonetheless, an extensively constant line force is achieved in the press gap of the roll press across the web width.

Improved roller construction forthe transport of film material

Patent JPS611558B2

Press section of a paper machine in which an extended-nip press is used

The invention concerns a press section of a paper machine, through which press section the paper web (W) is passed as a closed draw on support of a press fabric (11, 28) and of a smooth roll face (31). The first nip in the press section is an extended-nip press (NP 1 ) through whose press zone two opposite press fabrics (11, 28) that receive water have been passed. The upper press fabric in the extended-nip press (NP 1 ) is a pick-up fabric (11), which carries the paper web (W) from the forming wire (10). Downstream of the extended-nip press (NP 1 ), the paper web is directed between the two press fabrics (11, 28) onto a reversing suction roll (160) on whose suction zone (160a) the direction of the paper web is turned upwardly. In the press section, there are at least two other nips (N 1 , NP 2 ) that have been formed in connection with the smooth-faced (31) centre roll (30). The centre roll(30) is fitted at a level higher than the level of the extended-nip press (NP 1 ). The first of the other nips (N 1 ) is a roll nip and is formed by the reversing suction roll (160) and the centre roll (30). In this press roll nip, the press fabric consists of the pick-up fabric (11). The second other nip is formed by a second extended-nip press (NP 2 ) which has a press fabric (33) of its own that receives water.

Method of manufacturing a roll and a roll of the type used in a paper machine

ABSTRACT OF THE DISCLOSURE: A roll of the type which is used in paper machines has an inner roll body provided with an outer covering made up of a series of elongated strip portions which circumfer-entially surround the inner roll body while being distributed axially therealong and engaging each other. These strip portions are welded to each other and also may be welded to the inner roll body. The welding of the strip portions is carried out by way of an electron beam type of welding which can be oriented so as to achieve one or more of a number of different types of weld connections between the successive strip portions and, if desired between the strip portions and the inner roll body. Where the strip portions form part of an elongated strip which is helically wound onto the inner roll body, the welding by way of the electron beam can take place simmultaneously with the winding of the strip onto the roll body, and by suitable controls the welding can be con-tinuous welding or the welding may be applied at predetermined intervals to provide a discontinuous type of welding.

Method and system associated with a sensing roll including a first sensor array and a mating roll including a second sensor array for collecting roll data

Collecting roll data associated with a sensing roll and a mating roll forming a nip includes generating sensor signals from a first sensor array on the sensing roll and a second sensor array on the mating roll during rotations of the mating rolls and sensing rolls. A periodically occurring first time reference is associated with each rotation of the mating roll and a periodically occurring second time reference is associated with each rotation of the sensing roll. For a received sensor signal, based on whether the received signal is from the sensors of the mating roll or the sensing roll, a tracking segment on the other roll is detected that enters a region of the nip concurrent with the sensor that generated the received signal. The detection is made from either a most-recent-identified first time reference or second time reference. The received signal can then be stored using the detected tracking segment.

System and method for monitoring a band

Collecting data includes generating a sensor signal from each of a plurality of sensors (26A, 1302A) located on a sensing roll (918, 926), wherein each signal is generated when each sensor enters a region of a nip (212A, 1201) between the sensing roll (918, 926) and mating roll (940A, 942A) during each rotation of the sensing roll; wherein a web of material travels through the nip and a continuous band contacts a region of the web of material upstream from or at the nip (212A, 1201). A periodically occurring starting reference is generated associated with each rotation of the continuous band and the signal generated by each sensor is received so that the one of the plurality of sensors (26A, 1302A) which generated this signal is determined and one of a plurality of tracking segments associated with the continuous band is identified. The signal is stored to associate the respective sensor signal with the identified one tracking segment. (FIG. 10)
