Abstract
The detaching roller aggregate comprises two pairs of cylinders each consisting of a detaching roller and a printing cylinder which are pressed against each other by means of a contact pressure device. The contact pressure device is arranged in such a way as to press the two cylinders of the second pair against each other with a larger force than the force pressing the two cylinders of the first pair together. The ratio of the two forces may be approximately 1.2:1 to 2:1. Due to the larger force with which the cylinders of the second pair are pressed against each other, a more even top fleece is produced, in particular during the combing of relatively long fibers and/or at high processing speeds.
