Abstract
Highly compressed ceramic fiber conveyor rolls can provide desirable insulation coupled with extended wear for roller conveying of high temperature articles such as freshly made sheet glass. However, under harsh industrial conditions, as experienced with the conveying of heavy loads consistently at the upper end of operable temperature ranges, such ceramic fiber rolls may be subject to premature wear at the interface between an inner shaft and an outer ceramic fiber roll cover, as well as experience longitudinal roll cracking of the cover. It has now been found that both of these potential cover problems can be successfully addressed by placement within the cover of perforated, rigid disks. Such disks placed occasionally along the roll and within ceramic fiber cover, are particularly suitable for use with hardened covers, where the hardening is more concentrated towards the surface of the cover and the disks are present within a softer inner fiber core of the cover.
