摘要： Aspects of the present disclosure provide systems, methods, and computer-readable storage media that leverage image processing to determine fibrillation within pulp. Size and shape analysis, such as adaptive thresholding and binarization, may be performed on an image of pulp to determine a fiber area of fibers included in the image. Edge detection and morphological image processing may be performed on a plurality of sub-images of the pulp to determine a count of edges of fibrils included in the image and a sum of grey levels associated with the fibrils, respectively. A degree of fibrillation of the pulp may be determined based at least partially on the fiber area, the count of edges, and the sum of grey levels. Local statistical analysis and a Hough transform may be used to improve accuracy of the degree of fibrillation or to distinguish fibers from fibril clusters and fibrils within the image.

摘要： A sensor signal is generated from a plurality of sensors located on a sensing roll, wherein each signal is generated when each sensor enters a first nip between the sensing roll and a rotating component during each rotation of the sensing roll. A rotating applicator rod forms forming a second nip with the sensing roll such that each sensor enters the second nip during each rotation of the sensing roll. A periodically occurring starting reference is generated associated with each rotation of the applicator rod and the signal generated by each sensor is received so that a particular one of the sensors which generated the signal is determined and one of a plurality of tracking segments is identified. The signal is stored to associate the sensor signal with the identified one tracking segment.

摘要： A method and apparatus are described for controlling a coating head, which exerts a nip pressure to a fibrous web to be coated while the fibrous web is supported by a backing roll. An output signal of a sensor integrated within the backing roll is read, thus producing a measured indication of the nip pressure. A number of actuator control values are derived at least partly from said measured indication of the nip pressure. Said actuator control values are delivered as commands to a number of respective actuators that contribute to creating the nip pressure, to control an amount of a coating substance on the fibrous web in the coating head.

摘要： A method and apparatus for incorporating feature substances into a still moist but already sufficiently consolidated paper web provides for directing a feature substance suspension onto the surface of the paper web as a laminar jet with low jet pressure. A special pressure control circuit ensures that the jet pressure is always constant regardless of the number of parallel feature substance suspension jets directed onto the paper web. This makes it possible to incorporate a great variety of line codings in paper under the same process conditions without any visible changes in fiber structure occurring in the paper.

摘要： An ultraviolet beam from an ultraviolet radiation source is projected to an object having a fluorescent substance such as an adhesive-applied position on a continuous sheet of paper which is being transported and the luminous emission from the fluorescent substance is detected by light reception elements in a detection unit. In this case, at least more than two light reception elements are provided and the arithmetic process of the value of the output from each of the light reception elements is executed by a control computer disposed in a device main body. The value thus obtained is compared with a comparison value stored in storage means, thereby detecting the failure or the degree of adhesive application. When the failure of adhesive application is detected, an alarm buzzer is actuated while a lamp is turned on.The invention is therefore utilized for the inspection of portions to which an adhesive is applied in the adhesive application step carried out by collators, box-making machines, book-binding machines or the like.

摘要： A method includes forming an aqueous fibre suspension including cellulosic fibres from one or more raw material flows, and applying at least one chemical and/or physical control measure to the aqueous fibre suspension or at least one of its raw material flows for control of microbial activity in the aqueous fibre suspension or the raw material flow before an inlet of an intermediate residence entity. In this manner a starting ORP value for the aqueous fibre suspension is obtained. The aqueous fibre suspension is in the intermediate residence entity at least a minimum delay time. A final ORP value is measured for the aqueous fibre suspension after an outlet of the intermediate residence entity before the formation of the fibrous web. An ORP difference value between the starting ORP and final ORP values is calculated. Finally, the aqueous fibre suspension is formed into a fibrous web and dried.
