It will be appreciated that an improved high speed lid receiver has been described for in-line closure lids at high speed grinders. The transducer is an improvement over the known transducers in that the lids are fed more uniformly without tilting or misplaced to the moving containers and works favorably at high speed moving closely spaced containers . In addition, it has the improved lid sensor. a simpler construction allowing continuous observation by the operator of the machine. " is. The simplified design is a consequence of the fact that the rubber members for reversing. the lid and magnets on the front.
