Method for straight-line drawing of round material

Method for equalizing differences in drawing speed between a first material drawing machine operating in tandem with a second drawing machine disposed downstream from the first drawing machine, including a straight V-shaped material-guiding channel disposed between said first and second drawing machine having an interruption therein for admitting drawn material to a region of deflected material, disposed between said first and second machine, the method comprising the steps of:

• drawing the material through the first machine, guiding the drawn material in said channel from the point of material exit of the first machine via said interruption to the point of material entry of the second machine;
• deflecting the drawn material from said interruption to said region of deflected material in a direction and transverse to and away from said guiding channel;
• varying the length of the deflected material in response to said differences in drawing speed;
• drawing the material through the second machine;
• and moving said channel for ending said straight travel direction before deforming the material.

Method for reducing the cross section of round material, tubing, solid and hollow profiles by line drawing in at least two stages, including a first drawing machine, at least one second drawing machine operating at a discontinuous speed at the beginning of the drawing, while said first drawing machine is already operating continuously, disposed downstream of said first drawing machine along a given travel direction of material to be drawn, at least the second drawing machine having a second drawing die for straight drawing, and means for interconnecting the drawing machines and means for interconnecting the drawing machines and means for deflecting the material to be drawn from the given straight travel direction, and a guiding device being a circular guide, the method comprising the steps of:

• interconnecting said drawing machines;
• guiding the material to be drawn to the drawing die of the second machine;
• deflecting the material to be drawn by the second machine from the straight travel direction;
• drawing said material through a first drawing machine and guiding the drawn material from a tangential emission from said first drawing machine through a circular-arcuate deflection;
• subsequently feeding the drawn material as a tangential insertion into said second drawing machine;
• and absorbing the differences in feeding speed between said first and second machine by means of radial motion of the center of said circular-arcuate deflection while said first drawing machine operates continuously and said second drawing machine operates at a discontinuous speed so as to draw the material leading end through said second die.
