Wedge devices are used to increase the influence of rolls in a roll machines (mills and calenders) in the zone of processed material. These devices not only intensify rolling and calendering, but also promote degassing of the material. The technique of parametrical and thermal calculation of roll machines for processing of power-law materials is presented. Results of numerical simulation of processing of rubber on three-roll calender with the wedge device are presented. It is shown that key parameters of processing in a wedge gap are commensurable with similar parameters of processing in a roll gap the roll machines. Recommendations about an effective utilization of the wedge devices are formulated.
