FIELD: process engineering.
SUBSTANCE: proposed unit is intended for polymer material processing and producing various shaped products. Roll-screw unit is made up of rolls with endless friction produced by one stationary roll and second roll revolving at different peripheral speed. Stationary roll accommodates screw with individual drive to grip and transfer material, and to generate pressure ahead of moulding head. Stationary roll generating surface has square-section loading opening made in maximum-pressure zone at the distance of 0.085-0.1 roll radius from minimum clearance plane at angle equal to screw thread rise angle.
EFFECT: stable polymer processing, high efficiency, possibility to produce preset-section shaped products.
