Abstract
Device for detecting the presence or the absence of an article in the recesses of the feeding disc of a wrapping machine for candies, comprising a nozzle emitting an air jet directed against the portion of said disc carrying the recesses. Opposite to the nozzle emitting the air jet, there is provided a target member which is operatively connected, through a mechanical connection or equivalent means, to an electrical sensor located in a protective housing. If a recess which cyclically moves across the air jet contains an article, the latter intercepts the air jet so that the target member and sensor will be left at rest. If a recess does not contain an article, the air jet will impinge against and cause the displacement of the target so as to change the status of the sensor.
