     FIELD OF THE INVENTION 
     The present invention generally relates to a method and apparatus for manufacturing business forms and, more particularly, to a method and apparatus for producing multiple-die cut business forms for a variety of applications. 
     BACKGROUND OF THE INVENTION 
     U.S. Pat. No. 4,379,537 to Lomeli et al. discloses a business form with a removable label and a method for producing the same. According to the Lomeli et al. patent, a paper substrate in the form of either individual sheets or a continuous strip is fed into a paper processing apparatus. The paper process apparatus produces the business form having a removable label disposed thereon by a method comprising the steps of imprinting information on the paper substrate, applying transfer tape to the paper substrate, die cutting the substrate to form a label, and subsequently collating, cutting, or storing the resulting product. The disclosure of U.S. Pat. No. 4,379,537 is hereby incorporated by reference herein. 
     There are various devices that are currently available for producing business forms such as integrated labels in accordance with, for example, the method and apparatus disclosed in the Lomeli et al. patent. A number of such devices are commercially available from a company called Tamarack. The Tamarack devices produce a number of different types of business forms including label/form combinations, integrated labels, integral cards, fold and seal mailers, stencil/form combinations, continuous envelopes, affixed windows, promotional forms, and the like. A source of pin-feed paper having pin hole punching disposed at a generally uniform interval along both sides of the paper allow it to be fed through the device. Such Tamarack devices generally include a pin-feed paper infeed unit, a vacuum applicator unit, an unwind unit containing transfer tape, a hot melt applicator head, a feed control unit, and integral die cut unit, a hot melt unit, and a roll/fold/sheet delivery unit. Typically, the pin-feed paper that is fed into the Tamarack device is manufactured on a separate piece of equipment that, most usually, is owned and operated by a separate company from the company that runs the Tamarack device. 
     What is desired is an improved method and apparatus for manufacturing multiple die cut business forms. 
     SUMMARY OF THE INVENTION 
     It is desirable to provide a printing press that produces multiple die cut business forms in a variety of output configurations directly from stock paper via a continuous web, in-line process. 
     Such a printing press that produces multiple die cut business forms from stock paper via a continuous web, in-line process has a number of advantages. First, the costs of manufacturing business forms are reduced because the forms are produced with one piece of equipment. Second, the costs of manufacturing business forms is reduced because there is no need to perform any secondary operations on the stock paper fed into the printing press such as line hole punching. Third, the labor costs associated with manufacturing business forms are significantly reduced because a lesser number of personnel is needed to run the printing press during operation and there is no need for any separate affixing operations. 
     It also is desirable to produce a partially processed business form with a printing press such as, for example, the above-referenced printing press by a method including the steps of providing a glassine substrate, silicone treating the glassine substrate, and applying adhesive directly to the silicone treated glassine substrate. 
     Producing a partially processed business form in this manner has a number of advantages. First, the silicone treated glassine substrate can be utilized in printing presses as, for example, described herein with minimized curling. Second, pressure sensitive labels manufactured in accordance with this process can be utilized more effectively because, for example, the label can be easily removed from the substrate. 
     Other features and advantages of the invention will become apparent from the description that follows.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described presently preferred embodiments with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated. 
     A side view of one embodiment of a printing press  10  that is used to manufacture multiple die cut business forms according to the principle of the invention is shown in FIG.  1 . Printing press  10  comprises a number of individual stations that perform specified functions and are connected together by a continuous web  15  so that, for example, multiple die cut business forms may be manufactured in a variety of output configurations directly from a source of stock paper as described in greater detail hereafter. 
     Printing press  10  includes a receiver station  12  upon which a source of stock paper is mounted. In the embodiment shown in  FIG. 1 , the stock paper source comprises a roll  14  of stock paper that is rotatably mounted on receiver section  12  by means of axle  16 . Printing press  10  is used to manufacture multiple die cut business forms directly from the stock paper roll  14  without the need for any secondary processing such as line-hole punching or separate affixing operations prior to beginning the manufacturing process. 
     Printing press  10  includes two printing stations  20  and  22  that are connected to the receiver station  12  by means of a continuous web  15 . A die cutting station  18  is connected to the printing stations  20  and  22  by the continuous web  15 . Two printing stations  24  and  26  are connected in series by the continuous web to die cutting station  18 . The continuous web  15  connects an adhesive strip-patch station  28  to printing station  26 . Adhesive strip-patch units suitable for use with the present invention are commercially available from a company called Tamarack (Wauconda, Ill.). 
     Three post adhesive patch die cutting stations  30 ,  32 , and  34  are connected in-line with the adhesive strip-patch station  28  by the continues web  15  as shown. The continuous web  15  connects a finishing station  36  to the third post adhesive patch die cutting station  34  via punching station  38  as shown in FIG.  1 . The various stations  14 - 34  and  38  perform various operations in a predetermined order so that various types of multiple die cut business forms may be produced in the output configuration specified by finishing station  36  as discussed in greater detail hereafter. 
     One aspect of the present invention is that a roll of glassine paper may be utilized as the roll of stock paper  14  shown, for example, in FIG.  1 . Glassine paper is supercalendered, is manufactured principally from chemical wood pulps which have been beaten to secure a high degree of stock hydration, has a smooth finish, and is transparent. The physical make-up of glassine paper allows it to have a high degree of resistance to the passage of air, to be almost impervious to the passage of water vapor, and to be grease resistant. Glassine paper can be provided in various colors and, if desired, can be made opaque by the addition of various fillers as readily apparent to those of ordinary skill in the art to which this invention pertains. A glassine paper substrate is provided with a silicone treatment which typically may be accomplished at the mill where the substrate is manufactured. This allows, for example, pressure sensitive labels to be manufactured with reduced curling. 
       FIG. 2  is a schematic diagram that illustrates various operations that are performed by the printing press shown in FIG.  1 . Paper from the stock paper roll  14  may be die cut by die cutting station  18  in any desired shape as, for example, shown at location  40 . Preferably, the shape of the operation performed by die cutting station  18  is dictated by the type of business form being produced by the printing press  10  in a particular application. Locations  42  and  44  indicate examples of printing operations that can be performed by printing stations  20 ,  22 ,  24 , and  26 . It should be noted that printing stations can perform a variety of printing operations including, for example, multi-color printing as readily apparent to those of ordinary skill in the art to which this invention pertains. 
     One aspect of the present invention that provides significant cost advantages is that the printing press  10  totally eliminates the use of stand-alone, off-line affixing which typically is accomplished by means of a communicator, a web attacher, or other off-line affixing equipment that is totally separate from a prior art printing press. Utilization of the printing press  10  to manufacture multiple die cut business forms allows affixing to occur either on the front of a form to produce a reverse-frame stencil or on the back of the form to produce an integrated stencil via a totally in-line process. 
     Referring back to  FIG. 2 , the adhesive strip-patch unit  28  allows an adhesive patch  46  to be removably affixed to the paper backing from the stock paper roll  14 . Unit  28  may be programmed to allow patch  46  to have any desired length and shape. Die cutting units  30 ,  32 , and  34  perform post-adhesive patch/strip operations as needed in accordance with the type of multiple die cut business form being prepared in a particular application as desired and as shown at location  48 . Punching station  48  is provided in the continues web from receiver station  12  to finishing station  36  to allow the multiple die cut business forms to be produced by printing press  10  in a given application to have line-hole punching as shown at  50  and  52  or preformations.  FIGS. 3-5  show additional examples of the die cutting and punching operations that can be performed by die cutting stations  30 ,  32 , and  34  as well as punching station  38 . One aspect of finishing unit  36  is to process the multiple die cut business forms produced by printing press  10  in one of three output configurations: output roll form as shown at  54  in  FIG. 7 , cut sheet form as shown at  56  in  FIG. 2 , and fan-fold form as shown at  58  in FIG.  8 . 
       FIG. 6  is a partial sectional view of one embodiment of a multiple die cut business form  60  that is produced by the printing press shown in FIG.  1 . Business form  60  includes a substrate portion  62  that is die cut by the die cutting station  18  to form a die cut portion  64 . An adhesive patch  66  is secured to a desired portion of the business form  60  as shown. 
     The functions provided by the various stations of printing press  10  can be applied in any desired way to allow a variety of different types of business forms to be produced as discussed in greater detail hereafter. For example, one unique aspect of the present invention is that an adhesive patch can be applied to an integrated stencil, label, or pocket as well as delivering a finished product at the end of the printing press in cut sheet, continuous, or roll form which obviates the need for line-hole punching or any other secondary operations to be performed on the stock paper that is mounted on receiver station  12 . 
     Another aspect of the present invention is to allow multiple die cutting operations to be performed on a cut-sheet integrated label, stencil, pocket or the like while simultaneously printing graphics on the form, both prior to and after the application of an adhesive patch as well as post-operation die cutting and perforating. Materials suitable for use in the printing press  10  in this case include, for example, plastic, films, tough papers, tags, card stocks, vinyl, stencil material and the like. Additionally, an easy-removal thumb notch can be provided in a business form while it is being manufactured in-line in the printing press  10  by means of the die cutting stations  18  and  30 ,  32 , and  34  both prior to and after the application of the adhesive patch by station  28 . 
     Integrated stencils can be manufactured by printing press  10  in continues, cut sheet, or roll form by affixing stencil material in-line while simultaneously printing the form graphics, then die-cutting the back of the stock and removing the die cut material. This also provides the option of forming a label for address identification by die cutting the stencil material and leaving ties so that, for example, a die cut round cornered rectangle remains in the form after direct contact, non-contact, or thermal imaging processing. 
     Another aspect of the present invention is that the printing press  10  can be utilized to provide horizontal perforations at predetermined intervals on multiple die cut business forms that are processed by finishing station  36  either in cut sheet, continuous fan-folded, or roll form. Applications of the present invention in this context includes invoices, packing lists, bills of lading, letterhead and the like. In this case, the business form is provided with two labels, one of which would be formed so that it could be immediately removed during use and placed on an envelope on which will be printed the name and the address of the recipient and the sender. The other label would be formed by a die cut with a perforation around its perimeter, with or without a thumb notch. The second label has the sender and recipient information reversed. Such business forms are particularly useful for any formal document that would have to be executed and returned to the sender such as, for example, legal papers or mortgage documents. 
     Referring to  FIGS. 9-10 , exemplary multiple die cut business forms comprising a dual-language pharmacy label according to one aspect of the present invention are illustrated.  FIG. 9  shows three pharmacy labels  68 ,  70 , and  72  all of which include two sections having the same information printed in different languages.  FIGS. 9 and 10  show the English and Polish languages. The line-hole punching provided on both sides of the pharmacy labels is useful for dot-matrix printing or other line-hole type printing applications. However, it should be appreciated that this feature is optional because, for example, of the widespread use of laser printers. In any case, one side of the pharmacy label includes adhesive so that it may be bonded to a pill bottle  74  as shown in FIG.  10 . 
     During use, the pharmacist prints the relevant pharmaceutical information in different languages on both sides of each one of the pharmacy labels  68 ,  70 , and  72  and affixes the label to the bottle as shown in FIG.  10 . This embodiment of a multiple die cut business form has a number of unique advantages that generally prevent communication difficulties. For example, this embodiment is particularly advantageous in the home health care environment where the patient or domestic workers in the home do not speak the same language or speak different languages than emergency service personnel such as paramedics who service the area in question. For example, in a situation where a Polish speaking person was accidentally over medicated an English speaking paramedic arrived to render assistance, the use of the dual pharmacy labels shown in  FIGS. 9-10  allow the paramedic to immediately understand what type of medication was taken. This feature of the present invention allows patients to more precisely follow a prescribed prescription regimen and minimizes the potential danger for accidental over medication or poisoning. 
     From the foregoing, it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present invention. It is to be understood that no limitation with respect to the specific embodiments illustrated is intended or should be inferred. The disclosure is intended to cover by the appended claims all such modifications as fall within the scope of the claims.
