<p>An apparatus (10) for detecting the presence and position of a reinforcing strip (28) on a continuous slide fastener chain (F) comprises a detecting probe (14) connected to and rotatable with a lever means (11) into and out of the path of the fastener chain (F) travelling undirectionally in an assembling line. The lever means (11) is biased normally counterclockwise with a pressure adjusted to allow the probe (14) to pass through the fabric web of the fastener tape (T) but not through the reinforcing strip (28). A position detecting means (18) is operatively associated with the lever means (11) and responsive to the position or operation of the probe (14) for discontinuing the operation of the apparatus (10).</p> |
