<p>Two contra-running Bowden cables have sheaths fixed on the tractor side to an operating device, and on the machine side they are held at the end of the ejector shaft at the height of a setting disc which is connected with the elbow and coaxial with its swivel axis. On the circumference of this disc, the core of one Bowden cable runs from one side, and that of the other cable runs from the other side. The sheath ends are so mounted that their axes form tangents to the disc circumference.</p> |
