ABSTRACT:
An apparatus for delivery and removal of mandrel rods for use with rolling mills. A plurality of rocking levers are arranged one behind the other in the direction of rolling and are pivotable into upper and lower positions. Free ends of the levers are provided receivers for receiving the mandrel rod. The pivot or rocking levers are two-armed angle levers which are slidably mounted in two different positions such that in the first position the receivers on the angle levers are maintained in the vertical projection through the rolling axis and in the other position are offset from such vertical projection.
