Abstract: Un signal de commande standard pour une machine à former des bandes continues est momentanément interrompu et remplacé par un signal ou plusieurs signaux perturbateurs appliqués à une, à un groupe ou à la totalité d'une série de cellules de commande de la machine à former des bandes. Une ou plusieurs cellules de commande sont activées par un ou des signaux perturbateurs alternants qui produisent une action correspondante dans la ou les cellules de commande. Le ou les signaux perturbateurs alternent à partir d'une position neutre de la cellule et sont sélectionnés pour réduire au minimum les effets moyens sur une période donnée. Les effets du signal ou des signaux alternants sur la bande apparaissent dans la région de la bande qui est affectée par la ou les cellules de comman, de sorte que la disposition et la réponse de la ou des cellules de commande peuvent être déterminées en surveillant la partie de la bande qui est formée alors que le ou les signaux alternants sont appliqués à la ou aux cellules de commande. La ou les dispositions et/ou la ou les réponses de la ou des cellules de commande sont obtenues en mettant en corrélation le ou les signaux perturbateurs et un signal de propriété de bandes ou un signal de profil obtenu surveillant la bande formée par la machine. Le ou les signaux perturbateurs sont définis par une séquence binaire pseudo-aléatoire avec des signaux multiples sélectionnés de manière à être statistiquement indépendants les uns des autres. Afin de s'assurer que la bande n'est pas perturbée au-delà des spécifications définies, l'amplitude du signal perturbateur est de préférence augmentée graduellement et ledit signal est arrêté individuellement pour chaque cellule de commande lorsqu'une amplitude utilisable est atteinte.

Abstract: Apparatus (10) and methods for measuring dark and bright reflectances of translucent sheet material (2) are disclosed. The apparatus (10) comprises first optical means for illuminating one side of the sheet material (2) with a source of electromagnetic radiation. A portion of the radiation is transmitted through the sheet material (2) and another portion of the radiation is reflected by the sheet material. The apparatus (10) also comprises optical gating means (30) that is positioned adjacent the other side of the sheet material (2) in a fixed position relative to the first optical means. The optical gating means (30) absorbs substantially all of the transmitted portion of the radiation when switched to a dark state and reflects substantially all of the transmitted portion of the radiation back through the sheet material (2) when switched to a bright state. The apparatus (10) further comprises second optical means for collecting the reflected portion of the radiation and the portion of the trasmitted portion of the radiation reflected by the optical gating means (30) and retransmitted through the sheet material (2) to provide a total reflectance. The total reflectance has a dark reflectance intensity when the optical gating means (30) is in the dark state and a bright reflectance intensity when the optical gating means is in the bright state. The apparatus also comprises sensing means (60), responsive to radiation collected by the second optical means, for providing a dark signal having a magnitude corresponding to the dark reflectance intensity and a bright signal having a magnitude corresponding the the bright reflectance intensity. The dark and bright signals can be incorporated in known formulae to compute values for quality attributes of the sheet material (2) including opacity and color.

Abstract: A sensor (2) for use in measuring the clay content of a sheet (8) of paper during its continuous manufacture. The sensor produces electrical indications of the intensity of radiation transmitted through or reflected from the sheet (8) for each of a plurality of selected narrow bands of infrared radiation. The selected bands include a measurement band having a center wavelength selected from a peak absorption range (46,48,50) for kaolin and a reference band having a center wavelength selected from outside a peak absorption range for kaolin. The radiation bands are selected to minimize error resulting from differences in sensitivity to absorption by water.

Abstract: A light source module 100 for use with a multi-camera array 130 in a video surface inspection system includes a first light emitter 104 which extends lengthwise across the entire width of a sheet 106 to be inspected. Light from the first light emitter 104, which preferably comprises one or more fluorescent lamps, is received by a light guide 110 and carried by the guide to uniformly illuminate a band extending entirely across the width of the moving sheet. The light guide comprises a transparent thermoplastic such that the light receiving end 118 of the guide can be bent to define a plurality of sections which can be axially aligned with a corresponding plurality of fluorescent lamps. The light source module can also assist the inspection system in overcoming redundant data processing problems by providing second light emitters 134 which illuminate the sheet in overlapping portions 132 of the fields of view of adjacent cameras of the multi-camera array 130 to define data dividing points. Accordingly, duplicated data generated by the video cameras can be divided among the cameras at the defined data dividing points such that duplicated data is only processed once by the video surface inspection system.

The latter aspect may be used to produce an indication of moisture weight per unit area, wherein the indication is substantially independent on changes in the average temperature, and enables accurate measurement of the moisture weight per unit area of heavy grades of paper having moisture weights of up to 450 grams per square meter. The former aspect may be employed in measuring the moisture content of heavy grades of paper having moisture weights of up to 90 grams per square meter.

Abstract: A contacting thickness gauge comprising a unique surface follower (46). The bottom surface (56) of the surface follower (46) has both contacting areas (64,66) and non-contacting areas (62). The surface follower (46) is in substantially continuous contact with a moving sheet (2) and embodies an electrically conductive target having a target surface that intersects a magnetic field but is substantially free from contact with the sheet during normal operation. The surface follower (46) is designed to minimize damage to the sheet (2) that would otherwise occur from contact between the surface follower and a protruberance of the sheet, and to preserve the characteristics of the target surface.
