This discloses a carriage drawing machine with a Traction unit, the two in slideways on the machine frame parallel to the drawing direction having guided drawing slide. These two counter-rotating ones Draw sledges pull the stock in hand-to-hand operation endlessly. To carry out this lifting movement, the drawing slides are each with a two-armed lever connected by means of a common axis seated Doppelkurvenance be pivoted back and forth in opposite directions.
  • a further known drive system as for example in the EP 0 371 165 A1, comprises a rotating drum with a curved shape on the surface running webs to produce the counter-rotating Drawing carriage movements.
  • This deflection of the drawn material creates a buffer area for the movement of the drawn material, so that the preceding, in the continuous drawing process working drawing machine undisturbed can transport the material to be pulled into this emerging arch, while the subsequent drawing machine in intermittent operation during the drawing start the incoming Ziehgut can take over.
