FIELD: processing of polymers and compositions on their base by extrusion method; chemical industry for manufacture of baseshoes. SUBSTANCE: multiple die head has body with core and profile strips arranged in it. Passages of profile section are formed between core and strips for polymer; these passages are communicated with feed passage of head. Core has cruciform shape with passage for cooling system which has cruciform section. Profile of profile strips has form of quadratic curve with rounded-off edges. Profile strips are mounted on body by means of screws symmetrically relative to longitudinal axis of head. EFFECT: enhanced accuracy of obtaining required geometry of baseshoes. 4 dwg
