ABSTRACT:
A rotary compacting machine using rolling-compressing techniques in which loose fibrous material is rolled into a dense continuous cylindrical core in a compression channel. At the discharge end of the compression channel the continuous core is cut to the desired length individual rolls.
The improved cutting mechanism, subject to this invention is self-actuating, and it is capable to maintain the desired cut-length of the individual rolls without any supplementary metering or sensing elements. It overcomes the mechanical difficulties which were inherent in the cutting systems of prior art machines.
