No. 08/456,811, which was filed Jun. 1, 1995, and entitled CONTINUOUS MICRO-LABEL APPARATUS AND PROCESS. 
    
    
     TECHNICAL FIELD 
     The present invention relates to a method and apparatus for the manufacture and placement of elongated micro identifiers into various goods and articles, such as into cloth, labels, sewings and others. 
     BACKGROUND OF THE INVENTION 
     Identifying indicia have been placed on micro labels and micro dots for the identification of the origin of goods for some time and the uses thereof are expanding very rapidly. Manufacturers desiring to identify and control gray market goods and counterfeit goods, have numerous uses for micro labels and micro dots. In order to be most effective, the micro labels and micro dots must be concealed within the goods or the packaging for the goods such that they are not easily detected or removed. 
     Prior micro labels gave been directed to achieve the smallest micro label size practical and have typically been circular, i.e. “micro dots” or square shaped, i.e. “micro squares”. The prior micro labels have emphasized the micro size and making it as difficult as possible for the micro labels to be detected by the human eye. The micro labels heretofore utilized and concealed have been of such size and configuration that the width is substantially the same as the height, as in squares, circles and rectangles. 
     While manufacturing techniques are becoming more advanced and more efficient in making the micro labels, the efficient application of the micro labels to certain products and goods is too cumbersome and difficult and the micro labels are not therefore utilized to their fullest possible extent, despite a long felt need in numerous industries. 
     An example of such an industry is the clothing industry, where there are significant problems with gray market and counterfeit goods. However, micro labels heretofore available for concealment have not been sufficiently reliably concealed or affixed to clothing due to the small size, difficulty in handling and difficulty in efficiently attaching and concealing the micro labels to the clothing. 
     In the manufacturing process for micro labels, a series of unique identifiers are imposed on a continuous reel of microfilm, as shown in FIG.  1 . The typical microfilm is sixteen (16) millimeters (mm) wide and comes in numerous different lengths. While the unique identifiers on the continuous microfilm can be longitudinally or transversely arranged or oriented, the identifiers are normally configured transversely in a plurality of rows, each row containing the unique identifier repeatedly and serially imaged thereon. 
     In applications wherein a micro dot is to be cut from the microfilm, the size of the punch pin utilized to punch the microfilm and thereby create the micro dot corresponds to the size and relative horizontal and vertical spacing of the identifiers and rows of identifiers on the film, such that no matter where the microfilm is punched, at least one complete identifier is contained on the micro dot created. The microfilm is then typically punched by a micro film punches with a plurality of circular or square cross-sections, thereby creating a plurality of micro labels which then have to be concealed and affixed to the desired goods. 
     FIG. 3 shows an example of a micro label referred to as a micro dot. As can be seen from this magnified view, there is at least one complete identifier on the micro dot. 
     Efficiently and reliably concealing and affixing micro dots to cloth and clothing presents many problems, is very difficult and labor intensive. The micro dots are so small, they are difficult to handle, place and attach. For a typical clothing manufacturer to conceal and affix micro dots to clothing generally requires an additional and time consuming step in the manufacturing process. There has not heretofore been a sufficiently effective or efficient way to conceal or affix the micro labels into goods, especially on a rapid or commercial basis, although the need is well recognized. 
     The forenamed recognized needs have not heretofore been sufficiently fulfilled by any existing apparatus or method. The present invention addresses the problems and needs associated with the efficient and effective manufacture of more easily handled micro labels and the application of micro identifiers to certain goods such as cloth, clothing, labels, fabric and other goods. 
     The present invention, novel and unique from prior attempts to address the problems and needs identified above, cuts the microfilm containing a plurality of rows of identifiers longitudinally into continuous micro label strips. The continuous micro label strips are then handled according to the specific application. 
     Using clothing as an example, the present invention therefore has the advantage of being much more easily handled and sewable on or weavable into clothing or to labels and other tags, which are then affixed to the clothing.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts”(Article 1, Section 8). 
     Many of the fastening, connection, process and other means and components utilized in this invention are widely known and used in the field of the invention described, their exact nature or type is not necessary for an understanding and use of the invention by a person skilled in the art or science, and they will not therefor be discussed in significant detail. Furthermore, the various components shown or described herein for any specific application of this invention can be varied or altered as anticipated by this invention and the practice of a specific application of any element may already be widely known or used in the art or by persons skilled in the art or science and each will not therefor be discussed in significant detail. 
     FIG. 1 illustrates a section of a microfilm  1  from which three continuous micro label strips  1   a ,  1   b  &amp;  1   c  may be cut in conjunction with this invention. The microfilm  1  contains a plurality of transversely oriented and unique identifiers thereon to be used to track the items onto which the micro label is placed. The unique identifier shown in FIG. 1 is “123456789” and is preceded and followed by an indicia indicating the start and termination of the identifier, i.e. a separator, which in the example in FIG. 1, is a period (.). Therefore the unique identifier contains 9 characters and each separator takes the space of a character, making the continuous micro label strip a total of 11 characters wide. 
     While the examples shown use numbers as identifiers, letters, symbols, characters and other designs can likewise be used. 
     Each of the three continuous micro label strips shown in FIG. 1 contain 22 rows of 11 characters. Generally, if the continuous micro label strip is the width of the number of characters of the unique identifier plus the two separators, or eleven in this case, the longitudinal strip must encompass eleven rows in order to be assured that one complete identifier plus its two separators will occur on the continuous micro label strip. 
     In the example shown in FIG. 1, in the continuous micro label strip  1   a  the complete identifier plus its two separators occurs in the tenth and the twentieth line down, whereas in the continuous micro label strip  1   b  it occurs in the seventh and the eighteenth line down and in the continuous micro label strip  1   c , in the sixth and the seventeenth line down. 
     The typical microfilm is sixteen millimeters wide and sixteen one millimeter continuous micro label strips are typically cut from one microfilm, resulting in one millimeter wide strips. 
     FIG. 2 illustrates a section of microfilm  2  on which a plurality of like unique identifiers are longitudinally oriented into rows,  2   a ,  2   b ,  2   c  and so on. 
     FIG. 3 illustrates an example of a typical micro dot  4  cut from microfilm and containing unique identifiers. 
     FIG. 4 shows the overall process of a spool  6  containing microfilm  7 , with the microfilm being longitudinally severed or cut into a plurality of continuous micro label strips, strip  7   a , strip  7   b , strip  7   c , strip  7   d , strip  7   e , strip  7   f  and strip  7   g . FIG. 4 shows an example of continuous micro label strip  7   a  being wound onto an individual spool  8  for later use. 
     FIG. 5 illustrates a continuous micro label strip segment  15  with the unique identifier “0123456” contained thereon and surrounded by periods (.) as separators. The continuous micro label strip segment  15  was longitudinally cut such that the strip only contains one row of unique identifiers thereon and was cut to length  17 . The minimum length the continuous micro label strip segment  15  needs to be cut in order to be assured that each segment has one unique identifier thereon is the number of characters in the unique identifier, plus two for the two separators, times the pitch of the characters used, and then times two. 
     The pitch of the characters is the distance between the vertical center lines of adjacent characters, or pitch  16  in FIG.  5 . 
     FIG. 6 illustrates a continuous micro label strip segment  20  with the unique identifier “0123456” contained thereon and surrounded by periods (.) as separators. The continuous micro label strip segment  15  was longitudinally cut such that the strip contains two rows of unique identifiers thereon. 
     FIG. 7 illustrates a continuous micro label strip segment  25  which was longitudinally cut from a microfilm roll, with a length  30  and a width  31 . The unique identifier is the characters “123456789”, with periods (.) as the separators. The unique identifiers have been transversely imaged on the microfilm. 
     FIG. 7 illustrates the relationship between the width  31  of the continuous micro label strip segment  25  and the minimum length  30  required to maintain identifier integrity. A minimum product width would be equal to the length of the identifier plus two characters for the separators. Given the width  31  of the continuous micro label strip being cut to one identifier plus the two separator characters, the minimum length  30  required would be equivalent to the width in character times the line pitch. 
     FIG. 8 illustrates the more typical width of a continuous micro label strip segment  35 , having a width  37  and a length  36  and unique identifier “123456789”. In FIG. 8, the width  37  of the continuous micro label strip segment longitudinally cut from the microfilm is the width of two identifiers plus three pitches for the three separators which are periods. 
     Given a length  36  of two or more identifiers as shown in FIG. 8, each line is guaranteed to exhibit at least one complete identifier so a length  36  equaling two lines would suffice to have a least one unique identifier on each continuous micro label strip segment. 
     Although there are many known cutting means for severing the microfilm into a plurality of continuous micro label strips, FIG. 9 illustrates one such way. The microfilm  50  is fed under the microfilm cutter  53 , which includes axis  52  and annular blades  51 . The example illustrated in FIG. 9 shows the cutter  53  severing the microfilm  50 , with longitudinally oriented unique identifiers, into seven continuous micro label strips, namely segment  50   a , segment  50   b , segment  50   c , segment  50   d , segment  50   e , segment  50   f  and segment  50   g . Each segment in the example in FIG. 9 contains only one longitudinally oriented row, which includes a plurality of unique like identifiers. 
     The microfilm can also be cut by other known mechanical and laser cutting means. 
     Is FIG. 10 illustrates a continuous micro label strip segment  61  sewn to a section of cloth  60 . 
     FIG. 11 shows continuous micro label strip segment  65  sewn to clothing label  66 , which in turn is sewn to a section of cloth  67 . 
     FIG. 12 illustrates a section of cloth  70  from which several triangular clothing labels will be cut according to the pattern shown, namely, label  70   a , label  70   b , label  70   c , label  70   d  and label  70   e . Before the clothing labels are cut from the cloth according to the patterns shown, continuous micro label strip  71  is woven into the cloth  70 . 
     FIG. 13 shows an enlarged view of the continuous micro label strip  71  woven into the cloth from FIG.  12 . continuous micro label strip  71  is woven parallel to threads  81  and perpendicular to cross threads  82 . 
     The micro label strip can be woven into the cloth by utilization of known machinery and looms in the same manner in which cloth threads are woven on a loom or similar known equipment. The micro label strip can be attached to industry standard bullets and woven into the cloth, by known industry air weaving techniques or by known transverse arm looms. 
     The micro label strips which are woven can be one millimeter in width as an example, or less, and what length or continuous length desired for the application. 
     In compliance with the statute, the invention has been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the invention is not limited to the specific features shown and described, since the means herein disclosed comprise preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted in accordance with the doctrine of equivalents.
