ABSTRACT:
Tubular coverings for conveyor rollers for glass sheets heated to the softening point in a bending and/or heat treatment furnace, which have the special feature of having an outer surface, i.e. the surface that contacts the glass sheets, which is based on metal wires exhibit a reduced risk of marking the glass sheets and also exhibit a high temperature and wear resistance. Such tubular coverings are preferably used for covering the rollers present in the frontal and/or lateral positioning zones of the glass sheets on the conveyor.
