ABSTRACT:
A composite tobacco stream is built at the underside of the lower reach of an air-permeable belt conveyor below a suction chamber by showering tobacco particles of a first type into the corner between one marginal portion of the lower reach and a first sidewall bounding a tobacco channel at the underside of the lower reach, by thereupon showering tobacco particles of the first type into the corner between the other marginal portion of the lower reach and a second sidewall so that the particles form a first tobacco layer having a concave underside, by thereupon depositing a relatively narrow core consisting of tobacco particles of a different second type on the underside of the first layer midway between and spaced apart from the two marginal portions of the lower reach, and by thereupon showering tobacco particles of the first type over the core as well as over the marginal portions of the first layer. The core can be formed by showering tobacco particles of the second type directly against the central zone of the concave underside of the first layer, or by building the core on a separate conveyor and transferring the thus formed core onto the first layer.
