Abstract: A pulling device for drawing the product through the draw die comprises a drum around which the drawn product is wound as it issues from the die. The drum is driven in rotation and a device for putting the drawn product leaving the drum under tension causes the drum to operate in the manner of a capstan.

Abstract: The machine comprises in combination a fixed frame and a hollow tubular element rotatable in the frame. The rod to be polished extends axially through the tubular element. A pressure-applying device actuated by centrifugal force and pivoted to the tubular element applies polishing means radially against the rod as the device rotates. Means are provided for driving the tubular element in rotation.

Abstract: An elongated lever pivotable on a drum for winding a drawn product, between an extended position and a withdrawn position in which it is withdrawn into a cavity in the drum and reconstitutes the wall of the drum, carries a drawn product end gripping mechanism pivotable on the lever. The cavity is upwardly inclined, relative to the direction of rotation of the drum about its axis, from the lower edge of the drum. The element is a cranked lever having a first arm having an elongated shape roughly corresponding to the shape of the cavity and a U-section and a second shorter arm extending inside the drum. The lever is mounted by its cranked portion in the upper end of the cavity to pivot about an axis oblique relative to the axis of the drum. The gripping mechanism is mounted between the branches of the U-section at the end of the first arm remote from the second arm to pivot in the plane of the first arm.
