Abstract
An assembly is disclosed. The assembly has an adhesive layer, a protective film layer that is fused to a first side of the adhesive layer along a first length, and a cover layer that is fused to a second side of the adhesive layer along a second length. The first length is longer than the second length. The adhesive layer is wound in a roll. The second side of the adhesive layer faces outwardly from a center of the roll.
Claims19
An assembly, comprising:
- an adhesive layer;
- a protective film layer that is permanently attached to a first side of the adhesive layer along a first length of the first side of the adhesive layer, the protective film layer including an exposed protective surface that is non-adhesive;
- and
- a cover layer that is permanently attached to a second side of the adhesive layer along a second length of the second side of the adhesive layer, the cover layer including an exposed cover surface that is non-adhesive;
- wherein when the adhesive layer is wound in a roll, the first length extends from an outside end portion of the roll along a plurality of layers of the adhesive layer wound around a center of the roll, and the cover layer extends the second length from the outside end portion of the roll and ends slightly beyond an outside layer of the plurality of layers, an exposed adhesive surface of the adhesive layer being exposed after the cover layer and along the plurality of layers of the adhesive layer wound around the center of the roll;
- wherein the exposed adhesive surface of the adhesive layer faces outwardly from the center of the roll;
- and
- wherein when the adhesive layer is wound in the roll, the exposed cover surface of the cover layer that is non-adhesive faces outwardly from the center of the roll, and the cover layer extends continuously along the second length to cover the exposed adhesive surface at an exterior of the roll.

An assembly, comprising:
- an adhesive layer;
- a protective film layer, which includes a first film surface that is permanently attached to a first side of the adhesive layer along a first length of the first side of the adhesive layer, and a second film surface that is non-adhesive and that is disposed on an opposite side of the protective film layer as the first film surface;
- and
- a cover layer, which includes a first cover surface that is permanently attached to a second side of the adhesive layer along a second length of the second side of the adhesive layer, and a second cover surface that is non-adhesive and that is disposed on an opposite side of the cover layer as the first cover surface;
- wherein the adhesive layer, the protective film layer, and the cover layer are wound in a roll and the first length extends from an outside end portion of the roll along a plurality of layers of the adhesive layer wound around a center of the roll, and the second length extends from the outside end portion of the roll and ends slightly beyond an outside layer of the plurality of layers;
- wherein the second side of the adhesive layer faces outwardly from a center of the roll;
- wherein the cover layer, a portion of the adhesive layer that is permanently attached to the cover layer, and a portion of the protective film layer that is permanently attached to the portion of the adhesive layer form a cover having opposite exterior sides that are non-adhesive;
- and
- wherein when the adhesive layer, the protective film layer, and the cover layer are wound in the roll, the cover extends continuously along the second length to cover an exterior of the roll.

A method, comprising:
- providing a protective film layer that is permanently attached to a first side of an adhesive layer along a first length of the first side of the adhesive layer, the protective film layer including an exposed protective surface that is non-adhesive;
- providing a cover layer that is permanently attached to a second side of the adhesive layer along a second length of the second side of the adhesive layer, which is less than the first length, the cover layer including an exposed cover surface that is non-adhesive;
- providing the protective film layer, the cover layer, and the adhesive layer in a wound roll in which the second side of the adhesive layer faces outwardly from a center of the roll and the cover layer is disposed at an exterior end portion of the roll, wherein the first length extends from the exterior end portion of the roll along a plurality of layers of the adhesive layer wound around the center of the roll, and the cover layer extends the second length from the exterior end portion of the roll and ends slightly beyond an outside layer of the plurality of layers, an exposed adhesive surface of the adhesive layer being exposed after the cover layer and along the plurality of layers of the adhesive layer wound around the center of the roll;
- unrolling the roll starting with the exterior end portion of the roll;
- and
- exposing the exposed adhesive surface of the adhesive layer at the second side of the adhesive layer after the first length of the cover layer is unrolled from the roll;
- wherein when the adhesive layer is wound in the roll, the exposed cover surface of the cover layer that is non-adhesive faces outwardly from the center of the roll, and the cover layer extends continuously along the second length to cover the exposed adhesive surface at an exterior of the roll.
