ABSTRACT
It is easier to analyze the behavioral problems of running webs if the web is visualized as a matrix of material that has embedded in it a warp of very closely spaced threads or strings. Also, assume that the matrix is weak in compression in thin webs, but strong in tension, and that the primary purpose of the matrix is to hold the threads together. Further assume these closely spaced threads, running from beginning to end of the supply roll, determine the behavior of the web as it tracks over rollers and is acted on by environmental conditions. Think of these imagined threads as “tension members.”
