<p>A method and apparatus for extruding an object of undefined length capable of plastic deformation into another object of undefined length and smaller section, using the driving forces and the pressure developed in a viscous fluid surrounding the first object by the movement of a mobile member provided with a groove in its surface, the groove defining, together with the surface of a stationary member, a passage along which the first object is displaced towards a die by the action of the forces developed in the fluid by the mobile member.</p> |
