Abstract

Method for feeding and deformation of continuous material, comprising sealing, treating or controlling the movement of an elongated workpiece, characterized by; (a) a first stage comprising the operations of (I) exerting a first force on the surface of the workpiece lengthened in the direction of movement of said part, and (II) exerting a first pressure normal to the surface of the part, (III) keeping the difference between the first force and the first pressure below a predetermined value ; (b) a second stage that involves the operations: (I) exerting a second force on the surface of the elongated workpiece in the direction of the movement of the part, and (II) exerting a second pressure normal to the surface of the expressed workpiece, (III) keeping the difference between the second force and the second pressure below a second predetermined value: (c) exerting the said first force and first pressure simultaneously with the second force and the second pressure on the piece of work; (d) said first and second forces being obtained producing a viscous fluid circulation, which must be applied to the workpiece in separate lengths thereof to determine viscous drag forces on the workpiece.
