Abstract
A label sensor adapted for use with a labeller comprises an emitter, a receiver and a fibre optic bundle for transmitting an emitted beam to the receiver. The labeller is of the type which separates spaced-apart labels from a carrier by passing the carrier around the free end of a label splitter tongue member. An end of the fibre optic bundle is positioned in an opening of the splitter tongue near its free end to detect the leading portion of a label as the carrier passes over the bundle end. The use of a fibre optic bundle and its manner of mounting in the tapered end permits the positioning of the relatively bulky emitter or receiver remote of the compact free end of the splitter tongue member and provides a precise label sensing.
