Abstract
Apparatus for the continuous monitoring of the condition of the needle heads of a circular knitting machine which move past a predetermined point one after the other at a definite frequency comprising an illuminating component for producing a light spot in the form of a line situated in the plane of an illuminated needle head without light projecting laterally beyond it, said light spot being projected into an aperture substantially the size of the image of the light spot, a photo-receiver disposed behind said aperture and adapted to emit an electrical pulse signal in proportion to the luminous flux passing through the aperture, and a threshold value electronic device for receiving said signal, which when a pulse falls below a predetermined value and/or when there is a change in the predetermined time spacing of two successive pulses, delivers a warning signal.
