Abstract
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.
Claims12
A method for treating an outermost edge of a material in order to reduce the possibility that persons handling said material receive skin cuts, comprising the steps of:
- a) moving the material to a treatment position, and
- b) at said treatment position, forming a safety fringe of weakened material, at said outermost edge, and to a small distance from that edge, wherein said small distance is done up to 1/4" from that edge and depending upon the weight and stiffness of the material.
A method for treating the edge of paper products to reduce the possibility of such products tearing the skin and injuring people, comprising the steps of:
- a) moving the paper past a treatment position, and
- b) at said treatment position, treating the edge of the paper to weaken the structural strength thereof along the edge of the paper as it passes by said position,
- whereby, the edge of the paper so treated does not have the mechanical strength to support the sharp edge of the paper, and, so weakened, it is less likely to pierce or cut the skin of a person coming into contact with the paper.
