Cigarette filter monitoring apparatus (12) for monitoring cigarette filter sections is described. The apparatus comprises cigarette material conveyor apparatus (14, 16) for conveying cigarette material along a conveyor path. It also comprises a microwave sensor (26) located adjacent to the conveyor path to monitor such filter sections. The cigarette conveyor apparatus (14, 16) is constructed to convey elongate cigarettes with filter sections oriented transversely of the said conveyor path. A second microwave sensor (28) is located adjacent to the said conveyor path also to monitor such filter sections. The monitoring apparatus (12) may further comprise a microprocessor (34) connected to receive signals from the said first-mentioned microwave sensor (26) and the said second microwave sensor (28) and to provide an indication of the condition of the filter sections. A method of monitoring cigarette filters using such cigarette filter monitoring apparatus (12) is also detailed. |
