1. THE METHOD OF FORMING A HELICAL COIL OF SPRING WIRE OR THE LIKE ABOUT A CYLINDRICAL FORM IN INTIMATE ENGAGEMENT THEREWITH WHICH COMPRISES PROVIDING A CYLINDRICAL FORM OF THE DESIRED LENGTH, MOVING THE WIRE ALONG A PATH SUBSTANTIALLY TANGENTIAL TO THE FORM AND TRANSVERSELY THEREOF IN A PLANE SUBSTANTIALLY NORMAL TO THE AXIS OF THE FORM WHILE PRODUCING RELATIVE ROTATION OF THE PATH AND THE FORM CONTINUOUSLY AT A UNIFORM RATE ABOUT SAID AXIS, GUIDING THE MOVING WIRE AND BENDING IT IN SAID PLANE AT A POSITION SPACED FROM THE POINT OF CONTACT OF THE WIRE AND THE SURFACE OF THE FORM TO DEFORM THE WIRE IN A CURVE HAVING A RADIUS OF CURVATURE LESS THAN THAT OF THE FORM AND HAVING ITS CENTER OF CURVATURE ON THE SIDE OF THE WIRE TOWARD THE FORM, MAINTAINING THE STRESS IN
