摘要: An apparatus for defining a passageway through composition between first and second locations. The has cable pulling assembly support the assembly. capstan assembly, with part of guided in movement around axis engageable connected to mole so as cause engaged by be pulled is driven axis. circumferential groove, bounded surface extending axis, reception pulled. groove configured that circumferentially localized force applied operatively positioned tending avoid slippage groove.
