Abstract
In a rotary compacting machine using rolling-compressing techniques sheets of loose fibrous material rolled into a dense continuous cylindrical core in a compression channel, being confined by power driven boundary compression rollers. The circumferentially spaced plurality of compression rollers impart to the material of the core radial, tangential and axial forces. At the end of the compression channel the continuous core is cut to the desired length individual rolls. The skewing position of the compression rollers is automatically regulated and adjusted to obtain the desired density of the core and to provide means to cause the desired axial displacement of the formed core toward and away from the discharge end of the compression channel. To make this compacting process applicable to biologically active fibrous materials, such as agricultural forage crops at higher moisture contents, an applicator for chemical additives, such as preservatives, is incorporated into the system.
