Adhesive roller

Abstract

An adhesive roller for detritus removal having an elongated strip where the strip has both a backing layer and an adhesive layer overlying and covering a first side of the backing layer. The strip also has a first end, a second end and two spaced apart sides. The strip is wound from its first end and to its second end into a tubular cylindrical roller with the adhesive layer facing outwardly. An adhesive release coating also overlies at least a portion of a second side of the backing layer. The adhesive release coating may be either applied as a liquid coating, or may be a solid substrate. This adhesive release coating facilitates removal of individual sheets from the roller. Alternatively, a portion of the backing layer is crimped to form alternating peaks and valleys along at least a portion of the backing layer. These alternating peaks and valleys limit the amount of areal contact between the backing layer and the next inner adhesive layer of the roller to facilitate removal of individual sheets from the roller.

Description

BACKGROUND OF THE INVENTION [0001] I. Field of the Invention [0002] The present invention relates generally to adhesive rollers of the type used for detritus removal. [0003] II. Description of Related Art [0004] There are many previously known adhesive rollers used for detritus removal. These previously known rollers typically comprise an elongated strip having a backing layer. The strip includes two ends and two spaced apart and parallel sides. [0005] An adhesive layer is provided along a first side of the backing layer. Thereafter, the strip is wound into a tubular and cylindrical roller with the adhesive layer facing outwardly. Oftentimes the strip is wound around a tubular core and the tubular core is then rotatably mounted on a handle to facilitate rolling of the adhesive roller along the surface desired to be cleaned. [0006] After prolonged use of the adhesive roller for cleaning surfaces, the adhesive on the outermost adhesive layer or sheet of the adhesive roller becomes cov...

AI Technical Summary

Benefits of technology

[0014] An adhesive coating is then applied across substantially all of a first or outer side of the backing layer. Thereafter, an adhesive release coating covers at least a portion of a second or inner side of the backing layer and this release coating has a release strength which varies laterally across the strip. Consequently, after the strip is wound into a cylindrical roller with the adhesive layer facing outwardly, the adhesive release coating between the backing layer and the next inner adhesive sheet reduces the adhesion between the backing layer and the next inner adhesive sheet thus allowing the sheets to easily separate from the roller when desired. Some adhesion, however, between the backing layer and the next inner adhesive sheet is necessary in order to maintain the integrity of the roller in use.

Problems solved by technology

After prolonged use of the adhesive roller for cleaning surfaces, the adhesive on the outermost adhesive layer or sheet of the adhesive roller becomes covered with detritus and other matter and loses its adhesiveness.

However, because of the adhesion of the backing strip with the adhesive on the next underlying layer on the roller, the actual removal of single sheets, each constituting one circumference of the roller, is oftentimes difficult.

Frequently, the outermost sheet of the adhesive roller becomes torn during its removal.

Even though a uniform release coating covers the side of the backing strip opposite from the adhesive side, these previously known uniform release coatings, however, are of a relatively weak strength in order to ensure the integrity of the roll in use.

Even with these previously known adhesive rollers having both spaced perforations and/or a cut formed through the roller to facilitate separ
