The molding head of the extruder contains a body with a channel through which the material is supplied, a control channel of the head, made with the possibility of changing its cross-section, and a filter. The control channel of the head is made in the form of elastic ring membranes fixed in the body, forming a closed cavity filled with silicone fluid, and these membranes are made with the possibility of deformation under the influence of radial movement of the rods in the hollow guides placed in the body, and the deformation of the membranes leads to a change in the cross-section of the control channel of the head, which occurs automatically.
The utility model refers to the equipment of chemical engineering and can be used to form profile products from plastics by extrusion.
