The market launch of Voith s UniFilm and UniSize, two rubber roll covers for film and size presses, is the start of a new product series.
Voith developed the UniFilm rubber roll cover for use in film presses, while UniSize was specially optimized for the requirements of puddle size presses.
The UniSize roll cover has better mechanical properties than standard roll covers and therefore offers greater resistance in the event of web breaks.
i) Unisize rain (uniform drop sizes) was produced using the CSIRO Canberra rain tower, consisting of drop forming modules positioned 12.
s) for natural, unisize, and multisize rains (Table 2) were calculated in the following ways:
Unisize rain had consistently lower drop impact frequencies than either multisize or natural rain, particularly 2.
For the Sodosol there was a significant trend towards greater suction under seals formed by unisize rain (Table 5), particularly at lower rainfall intensities.
For Vertosols 1 there was a slight non-significant trend towards higher conductivity under multisize rain than unisize rain, within each intensity.
6 mm unisize at 120 mm/h), likely to have the highest rate of seal erosion, had moderate rather than highest infiltration rates.
