FIELD: rubber industry. SUBSTANCE: in the gap between annular casing 5 and core 9, rubber compound is heated to a temperature 10-25 C lower than curing temperature, and compound is then forced through shaper 32 by agency of gear pump 2,3. Compound is heated in the latter to curing temperature owing to shear deformation. The pump is provided with drive roll 4 to feed compound thereto. Casing 5 is secured to casing 6 of extruder 7. Core 9 coupled with casing 5 is mounted for rotation around worm 11 of extruder and has hollow shaft 10. The latter passes through hollow of worm 11 and is joined with rotation drive. Between conical region 21 of core 9 and worm 11, seal 12,13 with adapter helical groove is disposed. Apparatus may be employed for manufacturing unshaped rubber products. EFFECT: improved structure of apparatus. 3 cl, 1 dwg
