Abstract
Cigarettes, as they are grouped in batches to be packed, have their ends detected for firmness or for missing filter tips, by having an array of individually actuated plungers (9) applied to their ends. Each plunger is actuated by air pressure acting on a piston (13) integral with the plunger. If a cigarette (C) is faulty a protuberance (21) on the plunger engages a common impingement plate (20), whose oscillation causes a piezoelectric transducer (22) to emit a fault signal, enabling that cigarette group subsequently to be rejected.
