Abstract
PURPOSE: To form the high accuracy wraps of an equal pitch in the radial direction with ease and high efficiency by using the snakes of varying curvatures and widths in the lengthwise direction.
CONSTITUTION: Snakes 13 comprise connecting the snake pieces 13' which vary in radius r of curvature and width b in the lengthwise direction and whose width b becomes narrower as the radius r of curvature becomes larger, by means of links 16. After a strip plate 14 is fitted to the end 15 of the sankes 13, the snakes 13 are rotated about the leading end 15. At this time, the radial pitch of the strip plate becomes smaller as the diameter is larger. If after this the snakes 13 are moved in the direction perpendicular to the plane of the figure and are detached from the strip plate, then spring-back occurs in the strip plate but this spring-back amount is larger as the diameter is larger and therefore the spiral wraps of an equal pitch in the radial direction are formed.
