  • Apparatus and method for making a binder self-supporting
    Patent number: 5267804
    Abstract: An apparatus (10) for making a binder self-supporting has a right-angular shaped side wall (20) of a height approximately equal to the width of the spine (34) of a binder (30). The right-angular shaped side wall is perpendicularly connected to a right-angular shaped bottom wall (22). The right-angular shaped bottom wall (22) is affixed to the inside surface (38) of either the front or back cover (36) of the binder (30). Once the apparatus (10) is affixed to the binder (30), the open edge of the binder (30), which is opposite the spine (34), presents a box-like configuration. The edge (24) of the right-angular shaped bottom wall (22) is bevelled so that sheets filed in the binder (30) more easily pass over that edge (24).
