ABSTRACT:
A method 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.
