ABSTRACT:
An apparatus for detecting the presence and position of a reinforcing strip on a continuous slide fastener chain comprises a detecting probe connected to and rotatable with a lever member into and out of the path of the fastener chain travelling undirectionally in an assembling line. The lever member is biased normally counterclockwise with a pressure adjusted to allow the probe to pass through the fabric web of the fastener tape but not through the reinforcing strip. A position detector is operatively associated with the lever member and responsive to the position or operation of the probe for discontinuing the operation of the apparatus.
