ABSTRACT:
Bales or portions of bales of relatively dry compressed tobacco leaf laminae or ribs are heated microwaves, or in an to a temperature not less than 50.degree. C., and are immediately admitted into a shredding machine without previous cooling and/or breaking up. The moisture content of the shreds is raised to between 12 and 13.5% for admission into a cigarette maker, or such moisture content is raised well above the optimum value for further processing in order to increase the filling power of the shreds. The shreds are thereupon dried to reduce their moisture content to between 12 and 13.5% prior to conversion into the filler of a cigarette rod. Two or more different types of shreds can be mixed prior to admission into the cigarette maker. The rate at which the shredding machine discharges a stream of shreds is kept constant by monitoring the density of successive bales or portions of bales and by regulating the speed at which the bales or portions of bales are delivered to the shredding station in dependency on the mass of the respective bales or portions of bales.
