FIELD: construction.
SUBSTANCE: extrusive head contains the case executed demountable from two sections with a cooling system, forming among themselves moulding slot of profile sectional view. Moulding channels are connected with the feeding channel. In the top section are executed profile bleeders in the centre which surface is formed in the form of oval curved lines, and the oriels edges surface is in the form of a sinusoidal curved line with damping amplitude. The bottom section of the case contains recesses in which central part ledges of the oval form are formed and placed symmetrically to surfaces of curve recesses of the top section.
EFFECT: quality improvement of the construction profile.
