A device for the pneumatic inspection of smoking items

摘要

The machine has a roller (4) which turns about an axis of rotation (5) and has seats (6), each designed to receive a cigarette (2). For each seat the machine has a pair of caps (16) made of strong material, designed to connect with the ends of cigarettes so that at an inspection station (17), each cigarette is connected to a source (21) of a fluid which can subject the cigarette to the action of the fluid. A pneumatic/electric pressure transducer (23) is connected to each seat. The transducer issues a signal which depends on the action of the fluid and which indicates the state of the cigarette.
