     FIELD OF THE INVENTION 
     This invention relates to the field of pre-cut adhesive tape, and more specifically to a method and apparatus for color-coding communications cables (e.g., cable flag tape and method) using pieces of pre-cut tape (in some embodiments, color-code tape that is stretchable during installation and that has pressure-sensitive adhesive), that are provided on a release liner that is formed to be removed as two or more pieces of release liner without the human user having to touch the adhesive face as the human user wraps the color-code tape around the communications cable. 
     BACKGROUND OF THE INVENTION 
     Currently, conventional color coding of an electrical and/or fiber-optic communications cable is performed with pieces of colored tape cut from large rolls of bulk tape material, such as colored electrical tape having pressure-sensitive adhesive on the tape, and wrapped around the cable. The installation worker typically peels a length of tape from the roll and cuts the piece off using a utility knife (such as a box cutter or the like), scissors or diagonal cutters. A plurality of such pieces of tape are used, each piece of a selected particular color. Each piece is sometimes simply called a “color code” and is wrapped around the cable side-by-side to other such “color codes,” with a preferred spacing between the nearest wraps of color codes, and a specified sequential order of color codes for each particular cable. Each color-coded piece is wrapped several times around a communications cable (e.g., at least three circumferential layers are specified by some companies to meet their requirements). The order and colors of the color codes indicate what communications protocol is used by the cable, and identify one cable from the others at the point of installation. This conventional method leaves the possibility for errors in required lengths and installation errors (such as, for example, touching the adhesive with the fingers, rendering the adhesive less sticky, or having the tape fold over and stick to itself, or having the wrong spacing, wrap-to-wrap, between adjacent wraps of tapes on a cable). It is often desired to have the end of the tape cut at a desired diagonal angle, which is difficult and time consuming for the user to obtain using a utility knife, and the results are inconsistent from user to user. Additional problems that may be encountered include incorrect spacing, inability to accurately cost-manage materials used, flagging or peeling of installed color-coded tapes, and the need for the installer to continuously search for the accessible end of the roll of tape. This conventional method also leaves the possibility of accidentally self-inflicted user cuts, injuries and extended installation times due to the process described above, especially during cold or rainy weather. 
     Descriptions of various conventional adhesive tapes that include a release liner include patents on medical bandages and tape that releases from a wall when an end of the adhesive tape is pulled to stretch the tape. For example: 
     U.S. Pat. No. 4,744,355 issued to Faasse, Jr. on May 17, 1988 with the title “Hinged end wound dressing,” and is incorporated herein by reference. U.S. Pat. No. 4,744,355 describes a wound dressing in which the release liner halves are each divided into a release liner main body and a release liner edge strip. The release liner main body overlaps a portion of the edge strip and the two are hingedly secured together by a flexible hinge. 
     U.S. Pat. No. 5,088,483 issued to Heinecke on Feb. 18, 1992 with the title “Adhesive frame bandage,” and is incorporated herein by reference. U.S. Pat. No. 5,088,483 describes an adhesive composite having a conformable backing, a pressure-sensitive adhesive which is coated on at least a portion of the bottom surface of the backing, a permanent adhesive reinforcement which acts as reinforcing means for the backing, coated on the bottom surface of the film and a liner which is releasably applied to the adhesive coated surface of the backing. A delivery means may also be provided to allow delivery of the system without touching the adhesive. The permanent adhesive reinforcement is applied to the backing in an amount which is sufficient to provide some reinforcement to the thin film backing so that the composite wall not tend to fold back on itself or wrinkle under ordinary use. Preferably this permanent adhesive reinforcement is applied to the periphery of the backing. 
     U.S. Pat. No. 6,541,089 issued to Hamerski, et al. on Apr. 1, 2003 with the title “Stretch releasing adhesive tape with integral pull tab,” and is incorporated herein by reference. U.S. Pat. No. 6,541,089 describes an elongated length of a single or double-sided stretch-releasing adhesive tape that can be cut to a selected length with integral pull tabs for stretch-removing the tape from a substrate. The stretch-releasing adhesive tape can be provided as long strips or roll form. The elongated stretch-releasing adhesive tape article includes an elongate length of stretch-releasing adhesive tape defining a longitudinal axis. The stretch-releasing adhesive tape has a first surface and a second non-adhesive surface. The first surface includes one or more adhesive regions and one or more non-adhesive regions arranged along the longitudinal axis. At least a portion of the non-adhesive regions include a series of pull tabs arranged along the longitudinal axis that can be grasped in combination with the second non-adhesive surface by a user during stretch-removal of the tape from an associated substrate. 
     There remains a need for improved devices and methods for color coding communications cables and the like. 
     SUMMARY OF THE INVENTION 
     Presently there is no conventional product that provides solutions for the problems described above. The present invention provides solutions to these problems by providing pre-cut color-coded pieces of tape, each on a release backing, with all the issues described above in mind. 
     How it works: In some embodiments, each color-coded device (e.g., a piece of colored tape supplied on a roll or a Z-folded flat pack, or as one of a plurality of individually supplied tape pieces each on release-paper substrate) includes a pre-cut color-coded polymer tape having pressure-sensitive adhesive, in which the precut lengths of tape are predetermined based on each cable size to provide the correct amount of color code needed (e.g., in some embodiments, the pre-cut length provides the amount of tape needed for three wrapped layers of tape around the circumference of the cable). In some embodiments, each piece has a precut finish end with a geometric shape (e.g., in some embodiments, a diagonal angle) on one end to prevent peeling and flagging. In some embodiments, the color-code device also has a removable release liner that extends width-wise wider than the adhesive tape, in order to provide accurate spacing between color codes as may be required for installation per requirements of the customer. In some embodiments, quick-peel tabs are provided to access the color code without the need to continuously search for the accessible end of a roll of tape, and without exposing the human installation user to harsh weather elements.

     CodeRyt 
     Some embodiments of the present invention are given the name CodeRyt™. CodeRyt™ is designed to help aid in the color-coding process used in various industries. In some embodiments, the length and width of each pre-cut piece of colored tape is determined by the size of the circumference of the cables to be coded and the number of ultimate wraps as specified by the design engineers of the project (e.g., in some embodiments, half-inch cables will utilize about 4.7124 inches of color code tape. In some embodiments, the release liner will be two pieces, one or more of which will have a quick-peel tab, wherein the first release liner will be two inches long for the starting side and five inches long for the ending side for the remaining piece of color code tape). In some embodiments, each CodeRyt™ piece of tape also has a diagonal angle cut for the finish end (the end of the outer-most layer), which in some embodiments, includes a 35-degree angle cut on the finished end to reduce water settling at the outermost end, in order to provide resistance against peeling in different climate or weather conditions. This pre-cut diagonal end eliminates the need for the use of a knife or scissors, thus providing a safer, faster application. In some embodiments, the release liner provides a built-in guide that extends to one side (or in other embodiments, both sides) for accurate spacing relative to other additional color coding, providing a more accurate professional result, no matter how experienced the end user may be. In some embodiments, the release liner also has a peel-able quick tab for the removal of the release liner covering the starting point on the code tape. This allows for fast-start application and removal in harsh conditions without the need for great dexterity, since once the initial attachment is made, the remaining peel-able quick tab release liner is pulled along with the color-code application until the remaining Coderyt™ is applied in a tight, uniform fashion. 
     FIG.  1 A 1  is a top (plan) view of a color-code device  101 , according to some embodiments of the present invention. In some embodiments, color-code device  101  includes a length of tape  110  having a start end  111  (which will be the end of the inner-most layer when tape  110  is wrapped around a cable  99  (see  FIG. 1B )), and a finish end  112  (which will be the end of the outer-most layer when tape  110  is wrapped around a cable  99 ). In some embodiments, tape  110  includes a polymer substrate with a non-adhesive outer surface and a pressure-sensitive adhesive on the inner surface (the surface that is stuck to the outer surface of the cable  99 ). In some embodiments, tape  110  is made from 3M Scotch Vinyl Color Coding Electrical Tape 35, ¾-inch wide, or the like (Scotch® Vinyl Electrical Tape 35 is a premium-grade, 7-mil thick polyvinyl chloride (PVC) color-coding tape, such as available in a plurality of colors from 3M Company, St. Paul, Minn.).

     Each piece of color-code tape, according to the invention, is cut to the predetermined length and shaped at the finished end to have a diagonal edge that, when wrapped around a cable, sheds water better than a perpendicular finish edge that tends to gather water, and to delaminate or come loose and become a flag in the wind. In some embodiments, for example, the length is predetermined to provide three consecutive layers of tape when wrapped; in some such embodiments, a length equal to the cable diameter times pi times three, so for a cable of 0.5″ diameter (1.27 mm diameter), the length is about 0.5*pi*3=4.713″ (about 11.9 mm length); in some such embodiments, this length is the length from the start-end edge to the nearest end of the diagonal finish-end edge equal to the shortest of the two length-wise edges. In some embodiments, an additional 0.1 to 0.3 inches is provided to account for the thickness of the tape when the three layers are stacked around each other. Thus, in some embodiments, the longer of the two long edges is about 5″ long. For metric units, a person of skill in the art recognizes that each inch is 2.54 cm, so each inch-based measurement set forth can be multiplied by 2.54 to obtain the length in centimeters. In some embodiments, color-code devices  101  are supplied in kits having 10, 25 or 100 pre-cut color-code devices  101 . 
     In some embodiments, tape  110  has a start end  111  (in some embodiments, substantially perpendicular to the longest edge of tape  110 ) and a finish end  112  that is at a non-perpendicular (i.e., diagonal) angle to the longest edge of tape  110  (i.e., at an acute angle  114  to the longest edge of tape  110 , which, in some embodiments, is about 35 degrees). In other embodiments, other angles are used, wherein the angle is chosen such that the cosine of the angle  114  times the length of the finish edge  112  (equal to length  116  on FIG.  1 A 1 ) is at least 50% times the circumference of the cable, in order that the diagonal finish edge wraps around at least 50% of the cable circumference to shed water and reduce the amount of water from rain or dew that settles along that edge, thus reducing the tendency of the finish end  112  of the tape  110  to come loose from cable  99  once applied. In other words, in some embodiments, the angle  114  is selected so that the length  116  is at least 60% of the cable circumference. For example, when the width  116  of the tape  110  is 0.75″ and angle  114  is 35 degrees, then length  117  of finish edge  112  is about 1.31″, and distance  116  is about 1.07″, which is about 68% (i.e., more than 60%) of the 1.57″ circumference of a 0.5″-diameter cable. 
     In some other embodiments, the angle  114  is selected so that the length  116  is at least 50% of the cable circumference. As an example, when the width  116  of the tape  110  is 0.75″ and angle  114  is about 43 degrees or less, then length  117  of finish edge  112  is about 1.10″ or more, and distance  116  is about 0.084″ or more, which is at least about 51% (i.e., more than 50%) of the 1.57″ circumference of a 0.5″-diameter cable. 
     In some other embodiments, the angle  114  is selected so that the length  116  is at least 40% of the cable circumference. For example, when the width  116  of the tape  110  is 0.75″ and angle  114  is 50 degrees or less, then length  117  of finish edge  112  is about 0.98″ or more, and distance  116  is about 0.63″ or more which is about 40.06% (i.e., more than 40%) of the 1.57″ circumference of a 0.5″-diameter cable. 
     In some other embodiments, the angle  114  is selected so that the length  116  is at least 25% of the cable circumference. For example, when the width  116  of the tape  110  is 0.75″ and angle  114  is 62 degrees, then length  117  of finish edge  112  is about 0.85″, and distance  116  is about 0.399″ which is about 25.3% (i.e., more than 25%) of the 1.57″ circumference of a 0.5″-diameter cable. 
     In some embodiments, color-code device  101  includes a release liner  120  that has a cut and/or perforated line feature  121  that permits easy removal of release-liner portion  122  from the start end  111  of the adhesive tape  110  to the perforated line feature  121 , thus exposing the pressure-sensitive adhesive  115  (see FIG.  1 A 2 ) of the portion  113  of tape  110  previously covered by release-liner portion  122 , while release-liner portion  123  remains in place to protect the rest of the pressure-sensitive adhesive  115  from fingerprints and from sticking to itself. In some embodiments, the portion  113  is about one inch long to provide a firm starting adhesion to the cable being wrapped. In other embodiments, other lengths for portion  113  are used. In some embodiments, the finish end  124  of the release liner  120  is pre-cut flush even with the end  112  of tape  110 . 
     FIG.  1 A 2  is an end (elevation, but not to scale) view of color-code device  101 , according to some embodiments of the present invention. In some embodiments, release liner  120  has a width  129  that is wider than the width  119  of tape  110 , and the extra width  128  is provided only to one side of tape  110  and, in some embodiments, is used by the human user to obtain the proper spacings between the individually wrapped pieces of color-code tape  110 A,  110 B, and the like (See  FIG. 1G ). For example, in some embodiments, the width  129  of release liner  120  is 1.5-inches wide and the width  119  of the tape  110  is 0.75-inches wide, so that the extra exposed width  128  of the release liner  120  (i.e., 0.75 inches) can be used to obtain a 0.75-inch spacing between wrapped pieces of tape  110 . 
     FIG.  1 A 3  is a side (elevation, but not to scale) view of color-code device  101 , according to some embodiments of the present invention.
