Abstract
A floor polisher mounting disk for mounting a polishing pad on a motorized floor polishing machine is provided which is characterized by the ability to readily flex upon encountering a protuberance in a floor such as a door threshold. The mounting disk includes a hum portion and a rim portion which is positioned in spaced relation to the hub portion, resilient plastic means interconnecting the two portions for providing a pliable interconnection between the two, and a resilient lip extending from the resilient plastic means for mounting a polishing pad thereon. A method of forming the floor polisher mounting disk is also provided which includes the steps of injection molding a plastic hub and rim portion, annealing the same, and thereafter injection molding a relatively soft plastic material to overlie and interconnect the hub and rim portions.
