| Beside the traditional pile/counter-pile procedures at the ratio 1:1 and the full felting procedure with only pile or counter-pile rollers, Xetma Vollenweider was the first manufacturer to develop raising technologies with different ratios of pile and counter-pile rollers. Depending on the number of raising rollers in the drum, pile/counter-pile ratios of 1:2, 1:3 or 1:4 are realized. | | The higher the number of counter-pile rollers, the shorter and denser the raising pile turns out. This brings decisive advantages in the working of woven and knitted wears of which the base is to be intensively raised and made denser. The optimal ratio of raising rollers, specifically designed for the individual article, provides the user with higher production quantities at shorter running times. |
