摘要： A method and apparatus for identifying a moving web in a paper making machine are disclosed. The method includes of the steps of illuminating the web with the light from a transmitter, reflecting the transmitted light off the web, receiving the reflected light with a light transducer to produce an electrical signal corresponding to the intensity of the received light, and identifying the moving web based on the received signal. The intensity of the transmitted light is adjusted so that the received light signal from the transducer is normalized with respect to an optimum value. The apparatus includes a light transmitter, a light receiver, and a control and identification circuit which identifies the web based on a signal from the light receiver, and which adjusts the intensity of the light transmitter to optimize the reception of the signal from the light receiver in order to minimize the effects of environmental interference.

摘要： A system for control and monitoring of the circulation lubrication of the bearings of the revolving cylinders and rolls in a paper machine or equivalent in which lubrication oil is fed from an oil-lubrication center or centers through a system of pipes into lubrication points. From these lubrication points, the lubrication oil is passed back through a system of return pipes into the oil-lubrication center or centers. The system includes actuator panels placed and grouped in the vicinity of the lubrication points primarily above the floor level of the paper machine hall or equivalent. From the actuator panels, lubricant feed pipes are passed to several lubrication points placed in the vicinity. The actuator panels have a feed-back connected regulation loop for lubricant flow quantity provided for each lubrication point, which regulation loop includes an oil-flow regulation valve, an actuator motor for same, as well as an oil-flow measurement device and a regulation circuit.

摘要： Method and device for monitoring a moving web, such as a wire in a paper machine, a felt, or a material web, such as a board or paper web. A bar of radiation beams is directed at the face of the web to be monitored by a series of transmitters in a direction transverse to the direction of movement of the web. Radiation reflected from the web and the background is detected by a series of receivers. The measurement signals obtained in this way are passed to an electronic unit in which a quantity that characterizes the monitoring of the web is determined from the measurement signals. The approximate location of the edge, the edges, or of corresponding discontinuities of the web is detected "digitally" on the basis of the radiation beam of the radiation transmitter in whose area the greatest change takes place in the received radiation. The precise location of the edge or equivalent of the web to be monitored is determined analogously by comparing the amplitudes of the signals of the adjacent receivers placed closest to the last-mentioned radiation transmitter with one another.
