FIELD: formation of heat-softened materials, formation of shaped articles from plastic masses and rubber mixtures. SUBSTANCE: gear has extruder with extrusion head and two rolls mounted for opposite rotation. Two profile forming belts are pulled over one of specified rolls and over additional roll. Grooves for belts in additional roll are arranged at distance securing divergence of belts for release of formed profile of article. The other roll has annular groove securing convergence of belts with formation of space corresponding to profile of produced article. Given design of gear makes it possible to enlarge assortment of long-length articles of various profiles without replacement of extrusion head.
