ABSTRACT:
Roll for smoothing paper webs including a hard roll core and an elastic covering layer provided on an outside of the core. The elastic covering includes an elastic matrix material, and is structured to operate within a temperature range between approximately 25° C. and 150° C. The elastic covering is further structured to operate with a nip frequency of between about 0.3 Hz and 5 Hz, and to be regionally compressible and to operate with a surface compression amplitude of between about 15 μm and 50 μm. The covering is further structured for a total dissipated energy of less than approximately 0.9J/cm3.
