There is a distinct directional anisotropy in microwave backscatter from the surface of the East Antarctic ice sheet as measured by the C-band wind scatterometer carried by the ERS-1 satellite.

It is estimated that about 80% of existing vats are of the counterflow type.... In this type of vat, the slurry flows opposite to the direction of cylinder rotation, causing sheet formation to begin at the point of highest consistency. Although relatively thick plies can be formed(i. e., up to 0. 010 inch or 10 mils caliper, referred to as 10 "points" in the trade), a number of problems are associated with this method. Because the mold rotates opposite to the direction of stock flow, a portion of deposited stock is continuously washed off the mold, resulting in flocced fiber bundles that contribute to "blotchy" formation.

The principle of web formation on a cylinder former is virtually identical to that of a gravity decker.... A horizontal cylinder with a wire or plastic cloth surface rotates in a vat of dilute paper stock. Water associated with the stock drains through the mold and a layer of fibers is deposited on the cloth.... Because the mold rotates opposite to the direction of stock flow, a portion of deposited stock is continuously washed off the mold, resulting in flocced fiber bundles that contribute to "blotchy" formation. The sheet also has extreme directionality(fiber orientation) caused by the method of fiber deposition.(N. B. Directionality is usually measured by the ratio of tensile values obtained on machine-direction and cross-direction samples. Values of 5. 0 are typical for vat cylinder board, as compared to values below 2. 0 for fourdrinier papers.)

On estime qu'environ 80 % des formes rondes existantes sont du type à contre-courant, [...] Comme la forme tourne en sens inverse de l'écoulement de la pâte, une partie de la suspension déjà déposée est détachée de la forme par chasse d'eau; on retrouve dans la suspension de petits amas de fibres floculées qui contribuent à la formation d'un épair nuageux. Cette méthode de dépôt des fibres donne des feuilles extrêmement orientées. (Nota : On mesure, d'ordinaire, l'orientation des papiers par le rapport des longueurs de rupture dans le sens marche et le sens travers. Pour les machines à forme ronde, on obtient des valeurs supérieures à 5,0, alors qu'elles sont inférieures à 2,0 sur les machines à table plate.)

On-Top Formers. A feature common to all the formers discussed thus far is that the sheet plies are picked up and carried on the underside of the felt. This transfer method restricts operating speeds and sheet dryness levels. Another problem is that the sheet must be righted before it enters the press section; the usual procedure is to run the forming section in the opposite direction to the rest of the machine, and turn the felt over with a long carryback section. Less often, the delicate sheet is transferred from one felt to another entering the press section. The remaining formers to be discussed place the sheet on top of the felt or fabric. This approach eliminates the speed and dewatering limitations. But, housekeeping and maintenance aspects must be stressed since the sheet is more vulnerable to drips and spills.

French

Domaine(s)
  • Machines à papier
OBS

Les formeurs superposés. Les formeurs dont il a jusqu'ici été question ont pour caractéristique commune que les différentes couches de la feuille sont levées et transportées sous un feutre. La méthode de transfert qui prévaut alors limite la vitesse des machines et la siccité des feuilles. Un autre problème rencontré est qu'il faut aligner la feuille avant qu'elle n'entre dans la section des presses; la technique couramment utilisée consiste à installer la section de formation de sorte que le sens du trajet de la feuille y soit à l'opposé du reste de la machine et de faire tourner le feutre autour d'une longue section de renvoi. Plus rarement, la feuille, qui est fragile, est transférée du feutre à un autre feutre à l'entrée des presses. Pour ce qui est des formeurs dont il sera ici question, la feuille est placée sur le dessus d'un feutre ou d'une toile synthétique. Cette façon de procéder permet d'éliminer les limites de vitesse et d'extraction de l'eau. Mais elle impose davantage de travail de surveillance et de maintenance parce que la feuille est alors plus vulnérable aux ruissellements ou projections d'eau.

The principle of the rod coater is illustrated in Figure 18-12. Again, the sheet picks up the coating mixture from an applicator roll. Here, the doctoring and smoothing function is performed by a small-diameter roll or wire-wound rod which rotates in the opposite direction to the travel of the web. Since web tension is used to maintain pressure against the rod, this coating method is generally limited to heavier weight products that can withstand the tensile loading.

Geotextile grids are manufactured from polymer sheets using the production sequence illustrated in Figure 2. 16. The first stage involves precise punching of a regular pattern of holes into the sheet. This is followed by carefully controlled stretching of the sheet in one direction while it is gently heated.... If no further processing is carried out a uniaxial grid with narrow rectangular apertures is formed.... The term "uniaxial" arises from the alignment of the stretched polymer ribs and the greatest strength properties in one direction. An alternative form of geotextile grid may be produced by incorporating a second stretching stage where the uniaxial grid is pulled in the transverse direction to give a biaxial grid with a squarer aperture shape.... In this case the term "biaxial" refers to the fact that both the stretched ribs and the strength properties are aligned in two directions.

The direction of the [induced magnetic] field [of buried conducting bodies] is most generally measured by the dip-angle method(...). The source loop is in the vertical plane, and the receiving loop is linked to an inclinometer which is used to measure the angle with the horizontal of the plane in which it lies when the voltage induced in it is a maximum.(...) Dip angle measurements when properly interpreted can yield information on horizontal location, strike, dip, length and conductivity of a buried conducting sheet.
