Record 9 1994-06-23

English

Subject field(s)
  • Papermaking Machines
CONT

The unique results achieved with supercalendering are due to the intermediate fibrous rolls(sometimes referred to as bowls or filled rolls) which possess elastic or plastic properties. With the application of load on the nips, the metal rolls cause a depression or deformation on the fibrous rolls at the point of contact, and the deformation spreads out on either side of the nip(Figure 18-28). When rotated, this spread area will creep because of the constant effort of the material to return to its normal shape. This flow causes a relative motion of the filled roll surface against the metal roll surface, thus producing rolling friction, which helps to give the polishing and smoothing effects. The intensity of action is governed by the amount of plastic flow and by the nip contact pressure.

French

Domaine(s)
  • Machines à papier
CONT

Satinage. La calandre à satiner, ou supercalandre (gloss calender, supercalender), et la calandre à friction (friction calender, friction glazing calender) sont des dispositifs hors machine (off-machine) qui donnent au papier un aspect satiné ou surglacé par polissage énergique entre des rouleaux de métal et des rouleaux de fibres comprimées (filled roll, compressed fibre roll, paper roll), de coton ou de papier, et rectifiés au tour.

Subject field(s)
  • Placement of Concrete
  • Concrete Construction
OBS

Concrete cover shall be measured from the concrete surface(see also Clause 12. 8. 2) to the nearest deformation(or surface for smooth bars or wires) of the reinforcement. For textured architectural surfaces it shall be measured from the deepest point of the textured surface.

French

Domaine(s)
  • Mise en place du béton

OBS

L'épaisseur d'enrobage de béton est la distance qui sépare la surface du béton de la saillie la plus rapprochée (ou du point le plus près de la surface d'une barre ou d'un fil sans saillie) de l'armature. Dans le cas d'un béton architectural dont la surface présente une texture, c'est à partir de la partie la plus creuse de la surface qu'on doit mesurer l'épaisseur.
