The roll compaction behaviour of feed powders is primarily governed by two parameters: the maximum pressure and the nip angle. Although the maximum pressure can be measured directly using pressure sensors fitted in the rolls, it is not a trivial task to determine the nip angle, which is a measure of the size of the compaction zone and hence the ...

Pure center winders (Figure 2) use web tension or, when combined with a pressure roll, can use nip and web tension to control roll hardness. Note that on this type of winder, torque produces web tension. A pure center winder may be a single-position or continuous-operation turret winder and may be a shafted or shaftless operation.

For the roller wedge technique, an infrared pyrometer is installed to view into the roller nip where the strip and roll meet. This alignment technique serves two purposes. First, this technique prevents the pyrometer from viewing a reflected image of the hot furnace wall, as the pyrometer views a reflected image of the roll instead.

In this application the purpose of the nip roller may either be to (1) drive the winding roll or (2) to exclude air which is attempting to enter the winding roll as shown in Figure 1.2.
