The present invention includes a method of lining a core slot that includes the steps of unwinding a tube, separating a portion of the tube, inserting the tube into a core slot, and expanding the tube to line the core slot. The present invention also includes a continuous piece of helically-wound tubing that is wound on a spool along with an apparatus and method used for creating the spool of tubing. The method includes the steps of helically wrapping a web of material in an overlapping relationship to form a helically-wound tube, advancing the tube in a longitudinal direction of the tube and winding the tube onto a spool while at least a portion of the tube is being formed by the step of helically-wrapping. Method variations in which one or more of the aforementioned steps may be eliminated as appropriate, can be used for many other uses.
