The accuracy of perturbation solutions to stochastic groundwater problems

An apparatus for positioning a loop of strapping about an object at a strapping station preparatory to tightening the loop to shrink the same upon the object. A shuttle mounted for orbital movement in a closed horizontal path about the object receives and conducts the free end region of a length of strapping issuing from a dispenser and, during its orbital movement, carries such free end around the object and thus draws strapping from the dispenser and wraps the same circumferentially about the object to produce the loop.
