ABSTRACT:
An oiless surface for a bowling lane is formed from a high density polyolefin and particularly a high-density polyethylene having a reduced friction surface with alternating high and low points. The high points contact a bowling ball passing over or resting upon such surface and are sufficient in area and close enough in spacing to support such bowling ball passing across such surface from any substantial up-and-down movement. The reduced height points are low enough with respect to the high points not to be contacted by the surface of the ball and extensive enough in area to provide a surface exerting less frictional retardation upon the surface of a bowling ball spinning upon the surface than a flat, smooth surface made of the same material.
