Abstract
A rolling-compressing apparatus for forming loose fibrous material into continuous dense cylindrical core which is cut into individual rolls of desired length. The core forming channel is confined by a plurality of circumferentially arranged compression rollers. The improved suspension and drive mechanism of the compression rollers, subject to this invention allows the necessary angular movement of the compression rollers relative to the drive shafts of the main power drive train and utilizes effective means for the transfer of the driving torque.
