I cut my teeth on lead and oakum poured joints. Yes, it's called a "running rope" or a "joint runner". This is a asbestos rope with a attached clamp. We soaked the new rope in used motor oil to limber them up. May I ask why you're asking? Regards, Tom

Joint runner.
It has been so long since I have done horizontal cast iron I had forgotten. [looked it up on google]
Cast iron pipes for plumbing (http://www.plumbing-basics.com/pipes/pipes-cast-iron.htm)
Assembling horizontal joints
The same initial procedure applies in making horizontal joints as for vertical ones. Secure the two pieces of pipe firmly in place after making sure they are clean and dry. Any moisture might dampen the oakum, causing lead to fly out or prevent it from filling the joint properly.

When ready to pour the lead, first attach a tool called a joint-runner. It is made of asbestos and is attached close to the end of the bell. You pour the molten lead in at the top and it finds its way down and around inside the cavity. After the lead has cooled, remove the joint-runner and caulk the lead in firmly, as with vertical joints
