EMPLOYEE'S FINGERTIP CUT DURING AUTOMATIC MACHINE REPAIR
Investigation abstract
THIS SMALL BUSINESS PRODUCES TOROIDAL TRANSFORMERS VARYING IN SIZE FROM ABOUT AN EMPLOYEE #1, THE OPERATOR, STOPPED THE MACHINE AND WAS BACKING THE WINDING HEAD VERY SLOWLY. WHILE GUIDING THE LOOSE TURN OF WIRE, THE "EYELET" WAS BACK TO TOP CENTER. AS THE EYELET PASSED A FIXED PART, THE TIP OF THE FIRST FINGER OF HIS L EFT HAND WAS ABOUT TO BE PINCHED. HE PULLED HIS FINGER OUT, NOT QUITE QUICKLY EN OUGH, AND HE SUFFERED A SLIGHT CUT ON THE FINGERTIP. INCH TO ABOUT 5 INCHES IN DIAMETER. THE TRANSFORMERS ARE WOUND ON VERY SPECIALI ZED MACHINES. IN GENERAL, A SMALL AMOUNT OF COPPER WIRE IS LOADED (WOUND) ONTO A MAGAZINE WHICH ROTATES IN A VERTICAL PLANE. THE MACHINE SHUTS OFF AUTOMATICALLY . THE OPERATOR THEN MANUALLY REVERSES THE ROTATION OF THE MAGAZINE, SNIPS THE WI RE, THREADS IT AROUND A POST, AND BEGINS THE WINDING PROCESS. A PREVIOUSLY INSER TED PLASTIC TOROIDAL CORE IS WOUND WITH WIRE BY 3 VERTICAL GUIDE ROLLERS. ONE OF WHICH ADVANCES A SMALL AMOUNT WITH EACH WIND. THE PROCESS THEN BECOMES AUTOMATI C UNLESS SOMETHING GOES WRONG. IN THIS EVENT, THE WIRE SLIPPED OFF THE MAGAZINE.
