发明名称 Safety fringe for paper
摘要 A safety fringe is formed around the edge of paper products in order to reduce the likelihood of people receiving cuts. A softened and weakened fringe is formed by pressing a hard-surfaced mechanical member against a narrow strip near the edge of the paper. Many commonly-available machine parts are suitable for this purpose. A safety fringe can be formed at the mill or at any other stage in the processing or handling of paper.
