<p>Flame gas cutting machine incorporates a hinged arm, the inner leg of which is swivel-mounted on a vertical spindle, whilst its outer leg supports a rotatable length of shafting, which can be rotated round a vertical axis relative to the leg. To this is attached a horizontal support with at least two separated burners the length of the shaft being connected with the support for guiding the support to move parallel to itself. The machine permits magnification of the stencil outline. Also, it employs more than one burner which, may be advantageous.</p> |
