Zusammenfassung:A paper feeding roller construction including a core of foamed cellular resilient material which has a shore hardness which is not measurable to thereby provide extremely easy compressibility, and an annular skin of a relatively hard elastic material on the core for providing toughness and abrasion-resistance, with the annular skin being coated onto the core so as to retain the cellular structure thereof on its surface to provide air pockets.
