Abstract

A retaining and cutting device for positioning a leading edge of material at one end of a roll and for puncturing and severing the material a pre-determined distance from the leading edge after removing from the roll, the retaining device comprising elongated jaw members pivotally connected together, a closure member normally urging the jaw members together, and a cutter along one edge of at least one of the jaw members. Extensions of the jaw members are manually grasped to urge the jaw members into an open position for insertion of the next leading edge of material therebetween. The device may also be utilized as a cutting tool for opening sealed boxes and the like.

Claims

1. A combination of a material clamp, a roll of material and a cutter for cutting said material, comprising:

first and second narrow elongated arm members having opposing respective gripping inner surfaces, a first of said inner surfaces being convex and a second of said inner surfaces being concave in complement to the first inner surface, and said arm members being joined together at a pivot;

said inner surfaces urged by a spring towards one another into a closed position making contact with one another and the leading edge of material extending from said roll of material; and

said arm members being integral with respective first and second manual grasping elements, provided for urging said arm members about said pivot into an open position wherein said inner surfaces are not in contact with one another; and

a cutter having at least one cutting edge integrally extending from and perpendicular to one of the opposing surfaces of the arm members.

2. The combination according to claim 1 wherein said gripping inner surfaces are defined by a frictional surface portion engageable with a surface of said material.

3. The combination according to claim 1 wherein a said cutter is positioned at a distal end of at least one of said elongated arm members.

4. In said combination according to claim 1 wherein said first and second clamping members include looped grasping members.

5. In a combination tool according to claim 1 wherein said first and second arm members terminate in rounded ends.
