Abstract (en)
[origin: EP2238844A1] The machine (F) has multiple suction devices (51, 52, 53, 54) that are attached in parallel to a common negative pressure supplying channel (70), so that multiple working bodies provided in machine functional modules (M, T) of the machine are parallely applied with negative pressure by the common negative pressure supplying channel. Pressure rate characteristics of multiple suction devices are stably maintained between operating points of the machine. An independent claim is also included for a method for operating a machine in a tobacco processing industry.
