ABSTRACT:
A rotatable wheel assembly which is suited for use as a wheel calculator, including a wheel having an axial hole therein and bearing indicia on one of its faces, front and back covers between which the wheel is sandwiched, the front cover having a window opening therein for selective viewing of the indicia on the wheel face, and the back cover and the front cover being adhesively bonded to each other through the hole in the wheel, the bond providing a grommetless pivot or axle for the wheel. To inhibit contact between the adhesive bond and the wheel while maximizing the width of the axle relative to the size of the hole in the wheel, a mask having a hole therein which is of substantially the same size as, but not greater than, the hole in the wheel, is interposed between the back cover member and the wheel with the two holes axially aligned with each other. The entire assembly can be formed by machine or by hand, either from a unitary, generally rectangular blank of paperboard or like sheet material, the blank being divided into panels constituting the various components by fold and tear lines, or from such a blank which includes all components of the assembly other than the mask which can be formed from a separate strip of sheet material and individually positioned between the wheel and the back cover member before the blank is folded into its final state.
