A severing and spool assembly employs various weakening devices and techniques to provide a shear force along a narrow elongate portion of the web. One method involves scoring a paper web being spooled in a manner to provide for a controlled tearing along the scored web across its width. A portion of the web adjacent the origin of the score is attached to a take up spool using an adhesive flag member. The change in direction of the spool from roughly horizontal to nearly vertical places forces on the web sufficient to cause web tearing in a manner substantially following the score. High pressure air may be used to assist the vertical turn up action of the paper onto an empty spool. Other methods of creating the shear force portion or line include the use of lasers to weaken the paper and applying a thin layer and line of adhesive to the surface of the web such that the web attaches to the spool along the line and the creation of two score lines that may converge at the center of the web or be staggered in the case of very wide webs.
