Abstract
In apparatus for conditioning filter tow for subsequent production of cigarette filter rod a stream of filter tow is conveyed from a source by a first drive unit which delivers the tow into a conditioning station. A second drive unit delivers the conditioned tow to a rod-forming unit. A variable speed transmission is provided to allow independent control of the first and second drive units. The transmission may be replaced by an electronic speed control arrangement.
