Abstract
A weft or filling thread monitor comprises a wire-shaped feeler pin which is pivoted by a thread, against the action of spring force, in the region of a measuring field. The measuring field encompasses a light-emitting diode and a photocell and enables generating, in a contactless manner by the feeler pin, an electrical control signal which is related to the monitored thread. This control signal is infed to a first input of a gate switching stage, at the second input of which there is applied a machine-controlled reference signal. In the absence of the control signal there appears at the output a work signal suitable for shutdown of the machine. Due to these measures such thread monitoring apparatus, working with contactless signal triggering, can fulfil all of the requirements placed thereon.
