Abstract
An apparatus and method for moving a tubing along a path, according to which the tubing is engaged by an outer chain which is driven to advance the tubing. The chain is adapted to be deflected radially in response to an increase in the diameter of the tubing, and a plate is compressed in response to the deflection of the chain to accommodate the variation in diameter.
