B24d 11/00 [58] Field of Search.......................... 51/406; 225/38 3 Claims, 4 Drawing Figures References Cited UNITED STATES PATENTS 3,267,623 8/1966 Block.............,...v..................51/406 ROLL OF PRESSURE SENSITIVE ADHESIVE, ADHESIVE COATED ABRASIVE DISCS AND DISPENSER BACKGROUND OF THE INVENTION This invention relates to abrasive discs having a coating of pressure-sensitive adhesive on the back thereof and, in one aspect, to a dispenser for dispensing pressure-sensitive adhesive discs from a continuous roll of discs.

The prior art discloses a strip or ribbon comprising a first strip in the form of a chain of abrasive discs having a pressure-sensitive adhesive thereon and a second strip of flexible material covering the adhesive and being releasably adhesively bonded to the first strip. The resulting laminate is convolutely wound to form a roll which can be separated into individual laminated abrasive discs. Additionally, the prior art shows a dispensing device suitable for individually dispensing the abrasive discs and for retaining the release liner separated from said disc, see US. Pat. No. 3,267,623. Such a roll of discs and the dispensing means, while allowing the user to obtain a plurality of discs in a continuous roll, requires the additional expense of having aflexible covering to protect the adhesive coating and the additional trouble associated with separating the covering from the adhesive backing on the coated abrasive discs. Also, while such discs can be dispensed with the disclosed dispenser, the dispensing means does not have means for registering each disc with relationship to the cutting bar to insure that individual discs are severed from the roll.

BRIEF SUMMARY OF THE INVENTION It has been found that a roll of pressure-sensitive coated abrasive disc segments can be formed without the use of a flexible liner for protection of the disc or adhesive, and discs from such a roll can be indexed and dispensed individually without the trouble of having to sever and remove a layer of release liner. The abrasive roll of this invention comprises a concatenation of pressure-sensitive adhesive-coated abrasive discs connected with at least one other disc at a line of tangency, the concatenation of discs being convolutely wound to form a roll which can be easily unrolled. A dispensing device which has a severing edge substantially narrower than the greater width of the discs and having on each end of said severing edge a registering member will insure that individual discs are separated from the concatenation of discs at the line of tangency between adjoining discs.- The dispenser allows the easy and quick dispensing of the abrasive discs from the rollin the form of individual pressure-sensitive coated discs without the delay and mess caused by a protective liner.

BRIEF DESCRIPTION OF THE DRAWING A further understanding may be had by reference to the accompanying drawing in which:

FIG. 1 is a perspective view of a roll of abrasive disc segments mounted in the dispensing device of this invention;

FIG. 2 is an elevational view in partial section of the device of FIG. 1;

FIG. 3 is a vertical sectional view taken along the line 3-3 of FIG. 2; and

FIG. 4 is aplan view of a portion of a concatenate of abrasive discs forming a roll in accordance with this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the accompanying drawing in which like reference numerals refer to like parts, a convolutely wound roll of abrasive discs 10 is rotatably mounted upon a supporting shaft 12 within a dispensing unit 13. A core 14 about which the roll of discs have been convolutely wound is retained on the shaft 12 by a wall 15 within the dispenser 13 and by friction retaining means in the form of a spring-loaded ball 16. The supporting shaft 12 is mounted within the case 18 and extends either direction from the wall 15, there being sufficient space in the case as shown to mount two rolls of convolutely wound abrasive discs thereby allowing more than one grade or type of abrasive disc to be available in the dispenser simultaneously. It is possible to form dispensing units having only one or more than two rolls of convolutely wound abrasive discs, the exact number of rolls in a dispenser depending on the number of grades and types of abrasive disc needed in each dispenser.

For ease of carrying a handle 20 is mounted on top of the three-sided frame of the dispensing device making movement from place-to-place within a working area very convenient. A standard 23 projects from the frame in spaced relationship to the shaft 12 to allow a roll of discs to be easily placed on the shaft. The standard 23 supports a knife, forming a cutting edge 24, at its free edge and has a projection 26 placed on each end of the cutting edge 24 which project above said edge to define disc registering means which index the individual discs in the roll. A smooth surfaced retention member 22 is mounted on the standard 23 between the cutting edge 24 and the roll of abrasive discs 10 to re tain the disc on the end of the roll in a position to be easily reached. The successive discs 25 will remain in contact with the retention member 22 because of the pressure-sensitive adhesive disposed on the abrasive disc opposite the surface having abrasive granules disposed thereon. When it is desired to separate a disc from the roll of discs, the disc desired to be separated is brought forward over the projecting registering means and then down toward the cutting edge 24. The projections 26 will prevent an abrasive disc from being separated from the adjoining disc until the width of the disc between the projections 26 is equal to or less than the width of the cutting edge 24 exposed by the projections. By properly regulating the registering means 26, it is possible to form a spacing which insures that adjoining discs are separated only at the line of tangency where the adjacent discs meet. The cutting edge 24 is shown held in place by screws 21 which allow the removal of a worn cutting blade and its replacement with a new blade. The cutting edge may be permanently or removeably mounted using a variety of fastening means, e.g., metal screws, nut and bolt, rivet, etc.

FIG. 2 shows a sectional view of the roll of pressuresensitive coated abrasive discs 10 mounted on the supporting shaft 12. The roll 10 is held in place by the retaining means. When all of the abrasive discs have been dispensed, it is a simple matter to force the core 14 over the ball 16 and slide the core 14 off of the shaft, and insert anew roll of adhesively coated abrasive discs on the shaft 12.

in FIG. 3 an abrasive disc 30 is shown resting on the smooth retaining member 22 which supports the disc 30 in a position to be easily grasped when it is desired to separate the disc from the roll 10. In FIG. 4 a plurality of discs 25 are shown which are joined along perforated lines substantially tangent to the discs. The lines are not longer than one-half the radius of the discs and maintain the discs 25 in a concatenatious configuration with the discs joined at the lines or necks 28. The length of the cutting edge 24 exposed by the registering means 26 will generally be about the same width as the width of the necks 28 between the discs 25 thereby insuring that successive discs will be severed at the neck. The registering means 26 will align the neck 28 in proper index with the cutting edge 24 and also retain the neck in the proper position as the disc being dispensed is separated from the roll. The registering means, by holding the neck at the proper place for separation, allows separation of the discs using only one hand, there being no need to manually hold the roll or the disc with the neck in position to be severed. This is in contrast to prior art devices where no means are provided for holding the neck in the proper position and the discs must be manually indexed thereby requiring the use of two hands.

The dispenser of this invention is useful for dispensing a variety of items which can be produced in roll form. The items to be dispensed can be of irregular shape, the rear portion of one item being joined to the front portion of the succeeding item, the individual items having a neck, which is substantially narrower than the width of the remainder of the item in order to provide an area for indexing the item to be severed with relationship to the severing edge.

The abrasive discs of this invention can be formed from a wide variety of well-known coated abrasive products such as cloth, or paper-backed coated abrasives. The coated abrasive products used will have a flexible backing material which allows the abrasive to be convolutely rolled into a roll of abrasive disc segments.

Pressure-sensitive adhesives useful for coating disc are known in the art. Examples of such adhesives being vinyl ethers, acrylates, and rubber resin disclosed in US. Pat. Nos. Re.24,906; 2,485,295; etc. The presently preferred adhesives, because of their extended shelf life and resistance to detackifying under atmospheric conditions, are arcylic copolymer adhesives disclosed in [1.5. Pat. No. Re.24906. One example of such an acrylic copolymer is a 95.5:4.5 isooctylacrylatezacrylic acid copolymer. Such a copolymer can be coated on the back of a concatenate of coated abrasive disc segments as a solution in heptanezisopropanol solvent and the heptanezisopropanol solvent evaporated leaving a pressure-sensitive adhesive having an extended life.

Various modifications and alterations of this invention may become obvious to those skilled in the art; it is to be understood, however, that the scope of this invention is not to be limited to the specific illustrative examples or materials described herein but includes those changes coming within the scope of the appended claims.

What is claimed is:

1. An abrasive disc product comprising a convolutely wound concatenation of coated abrasive discs having disposed on the side opposite the coated abrasive a pressure-sensitive adhesive, each of said discs being joined to at least one other disc along a perforated line substantially tangent to the discs and said line being less than half the radius of the discs and with the adhesive coating placed in releaseable contact with the abrasive coatingto maintain the wound roll and permit easy separation and application of the discs.
