Controlled tension winding apparatus

Claim 1

IN A CONTROLLED TENSION WINDING APPARATUS WHEREIN STRIP MATERIAL IS WOUND ONTO A ROLL WHICH INCREASES IN DIAMETER AS THE WINDING OPERATION PROCEEDS, A WINDING REEL FOR MOUNTING THE ROLL, VARIABLE SPEED DRIVE MEANS FOR SAID REEL, GUIDE MEANS OVER WHICH THE STRIP MATERIAL PASSES AS IT APPROACHES SAID REEL, A SUPPORT FOR SAID GUIDE MEANS, PIVOT MEANS MOUNTING SAID SUPPORT FOR SWINGING MOVEMENT THEREABOUT, MEANS FOR LATCHING SAID SUPPORT IN A PLURALITY OF SWUNG POSITIONS ABOUT SAID PIVOT MEANS TO THEREBY LOCATE SAID GUIDE MEANS IN A PLURALITY OF POSITIONS IN ALL OF WHICH THE STRIP MATERIAL MAKES A SUBSTANTIAL CHANGER IN DIRECTION AS IT PASSES THEREOVER WHEREBY THE TENSION ON THE STRIP MATERIAL PRODUCES A FORCE PERPENDICULAR TO SAID SUPPORT WHICH FORCE, FOR ANY PARTICULAR STRIP TENSION, INCREASES AS THE DIAMETER OF THE ROLL INCREASES, SENSING MEANS FOR SENSING THE FORCEPERPENDICULAR TO SAID SUPPORT, AND MEANS OPERATED BY SAID SENSING MEANS FOR OPERATING SAID VARIABLE SPEED DRIVE MEANS TO REDUCE THE SPEED OF SAID REEL SO AS TO MAINTAIN THE TENSION IN THE STRIP MATERIAL AT THE LEVEL NECCESSARY TO KEEP CONSTANT THE FORCE PERPENDICULAR TO SAID SUPPORT.
