摘要 |
In a cigarette tipping machine an apparatus for monitoring the size and position of cork patches (12) comprises a rotary knife (13) which cooperates with the surface of a rotary drum (11) to cut a strip (10) of material into a series of spaced patches (12). At the instant of cut a generator (15) produces a reference signal and when the leading edge of a patch passes an optical detecting head (14) a patch signal is produced. The reference and patch signals are processed in a circuit (16) and a fault signal is produced if the delay between the two pulses is outside an acceptable range.
