[0046] standard test method

[0047] Use the following test to determine the tendency to level on a particular surface: Set the roller of the test strip on the roller handle or floor roller tool and remove any covering wrap. The distance from the free end of the sheet to the end of the low adhesion zone (distance A) was measured with a ruler and recorded. The distance from the free end of the sheet to the start of the immediately underlying low adhesion zone (Distance B) is measured and recorded. When the free end of the strip is not completely interleaved with the low adhesion zone of the next sheet, then distance B is recorded as a negative number. Using moderate force, roll the strip roller back and forth across the test surface at least two times, each with a distance of two or three feet. If the lint strip unwinds from the drum and adheres to the test surface during the test, a flat score of 1 is recorded, otherwise a score of 0 is recorded. To proceed with additiona...

preparation example

[0064] Example lint rollers 20-35 were prepared in order to determine whether the lint rollers required a low adhesion zone along the entire leading edge of the strip roller.

[0065] The prepared lint strip samples had the properties shown in Table 4. The strip backing (cast polypropylene) and adhesive composition (based on synthetic rubber resin) used is similar to Scotch TM Those used in lint roller products (available from 3M Company, St. Paul, MN). Cover the entire width of the lint strip with the adhesive coating, except for approximately 0.25 inches of uncoated longitudinal strip at each edge.

[0068] 1 Peel adhesion to steel is according to PSTC 101, Test Method A (Pressure Sensitive Tape Association, 15 th Edition, 2007) were measured.

[0069] 2 Drum unwind force is based on PSTC 8 (Pressure Sensitive Tape Society, 15 th Edition, 2007) were measured.

Abstract

Unwinding, or "lanemarking," of lint roll tape during use can be greatly minimized or eliminated by providing a roll of tape that comprises a backing having a first side and a second side, an adhesive on the first side of the backing, a plurality of separation lines separating the tape into sheets, a low adhesion zone adjacent each separation lines extending in an upweb direction along the tape from the separation line. The low adhesion zone has a lower adhesion than the adhesive. Each separation line extends beyond the next adjacent and underlying low adhesion zone.

Description

Background technique [0001] The present invention relates to lint rollers. In particular, the present invention relates to lint rollers that include a leading edge that includes regions of low adhesion. [0002] Use lint removal strips on a roller to remove lint and other small particles from surfaces such as fabrics, carpets, furniture. Remove the strip from the tumbler only after use to dispose of it. In roll form, lint removal tape typically has an adhesive side of the tape that appears rolled for use. Rollers for lint removal strips are commonly used on applicators. [0003] Strip rollers are usually perforated to allow for easier removal of individual sheets. figure 1 A conventional roll of lint strips 1 is shown, wherein each sheet includes a separation line 2 to allow easy removal of the sheet. Such as figure 1 As shown, the strip may include an uncoated edge that will create a small tab to facilitate gripping the outermost portion of the sheet during removal. f...
