FIELD: plastic metal working. SUBSTANCE: apparatus for continuous extrusion includes wheel having at least one groove. Wheel is mounted with possibility of rotation. Outer in radial direction portion of grooves is restricted by arc-shaped tool having outlet opening in attachment of die and stop shifted in rotation direction from outlet opening. Attachment of die is in the form of body restricted by portion of cylindrical surface reciprocal to portion of cylindrical surface of wheel and by surface spaced from portion of cylindrical surface and having central recess. In said opening there are extrusion drift of die connected with chamber for feeding extrudate and having ducts connecting extrudate feed chamber with annular grooves of wheel and extrusion drift arranged in center of recess and secured by means of bolt screwed to die attachment at side of recess. Thin-wall copper tube may be made by means of such apparatus. EFFECT: enhanced characteristics of continuous extrusion apparatus. 6 cl, 5 dwg
