Method and apparatus for simultaneously assembling two or more tobacco layers (8) to produce two or more Continuous Cigarette rods. The aim of this invention is to eliminate any assistance of the presently used mechanical or additional pneumatic means for a division of the tobacco particles (3) into two or more equal amounts. The division is achieved exclusively by means of two or more conveying airflows (10). A flow of tobacco particles (3) is conveyed upwardly in a duct flow (4) through a rectangular suction duct (2) towards two or more bottom branches (5) of two or more parallel air-permeable suction bands (6) of a suction conveyor apparatus (1). The bottom branches (6) are separated by one or more partition members (7) for assembling two or more tobacco layers. Each partition member (7) has a downward facing surface (9) for a smooth division of the duct airflow (4) into two or more conveying airflows 10. Provisions are made for regulating the amount of tobacco particles (3), so that each assembled tobacco layer (8) contains an equal amount of tobacco particles (3). There is also a provision for adjusting an equal velocity of two or more conveying airflows (10) along the width of the rectangular suction duct (2). Without this provision of this adjustment, the velocity would considerably vary due to a gradually increasing height of the tobacco layer (8) during its assembly, which would then lead to a considerable decreased quality of the assembly tobacco layer (8).
