All BETA machines are equipped with the Beta-Roll®, an exclusive BETA patented system whose principle is based on a very simple mechanical system.
This patent underwent further modifications and improvements in order to allow its use for Calender’s rolls too. In fact, in 2002 a new patent was released, which assures the maximum uniformity for both the calendering pressure and the temperature of the roll’s surface.
The Beta-Roll® is now produced in two main versions, one for padders and one for calenders, and can be used with working width up to six meters. The Beta-Roll® is parallel ground and allows to reach great working pressures (linear pressure up to 100 N/mm for padders and 300 N/mm for calenders) with no deflection along the whole roll’s surface and at all working pressures, from zero to the maximum value.
