发明名称 Supercalendar roll with composite cover
摘要 The bone-hard supercalender roll of the present invention comprises: an elongate shaft having a longitudinal axis; a core layer formed of fibrous material circumferentially covering the shaft; means for compressing the core layer along the shaft longitudinal axis; an intermediate layer circumferentially covering the core layer that comprises a first polymeric resin and a heavy textile material; and an outer layer circumferentially covering the intermediate layer that comprises a second polymeric resin and a reinforcing material. In this configuration, the roll can provide the requisite bone-hard surface for calendering applications, but can do so without the surface denting and marring problems associated with filled rolls and the expense of rolls formed of covered metal cores.
