the invention relates to hair rollers and provides for the use of a cylindrical tube rolled from a rectangular perforated sheet of flexible material , the sheet having an outer edge which overlaps a portion of the tube . the tube has a pair of opposing transverse edges , each of which is engaged within a spiral groove formed in opposing caps . the caps are rotationally mounted on an elongated shaft , such that rotation of the disks causes advancement of the transverse edges within the sprial groove , changing the diameter of the outer tube , as desired . an indicia on the outer surface of one or two caps allows to select the diameter of the tube when rotating the caps . the shaft has slotted projections on opposing ends with one or both of which an elongated resilient band is engaged .
