APPARATUS AND METHOD FOR TREATING PRODUCTS

摘要

An apparatus for treating products continuously fed to the apparatus includes a first roller rotatable around a first rotation axis and a second roller rotatable around a second rotation axis parallel to the first rotation axis. A treatment gap is formed between the first roller and the second roller. The apparatus further includes an adjusting means for in-line adjusting the nominal size of the treatment gap. The adjusting means includes at least one piezoelectric element for shifting the position of the first rotation axis and/or the second rotation axis.
