A reflector is provided which produces from an incident light projected from one of two portions confronting each other at the gap of the sensor body to the other portion a reflected light offset with respect to the incident light in a direction lateral to the longitudinal direction of the weft yarn passed through the gap.

Weft yarn sensor

Catch yarns are drawn between a pair of rotatable members which are mounted to be movable toward and away from another and yieldably urged to come together. Detecting means detects the relative movement between the pair of rotatable members and produce an alarm-signal when the relative movement of one rotatable member away from another reaches a predetermined increased value. The catch yarns in tensioned state are further utilized to hold the detecting means at a rest position thereof. The detecting means also produces an alarm-signal upon the breakage of the catch yarns.

Apparatus for detecting malfunction on drawing of catch yarns in a

At least one of light projecting and receiving faces has a form which is elongate in the longitudinal direction of a weft yarn passed from the aperture of the sensor body to the outside of the aperture through the gap and is about equal to the thickness or size of the weft yarn in the direction of movement of the weft yarn passed through the gap.
