Roll, roll production apparatus and method for producing roll

Abstract

Rolls easy to be produced are provided. The invention provides a roll which is composed of a main tape cylindrically wound up. The main tape is provided with a first and second holes, respectively, in its winding terminating position and winding initiating position. First and second adhesive tapes are stuck over the holes, respectively. In the bottoms of the first and second holes, adhesive layers of the first and second adhesive tapes are exposed. Therefore, the main tape is stuck on a core at its winding initiating position and on the roll itself at its winding terminating position. Information may be printed on a surface of the first adhesive tape.

         1 . A roll comprising a main tape cylindrically wound, the roll comprising a first adhesive tape having an adhesive layer and a print layer laminated thereon, 
 wherein said adhesive layer of said first adhesive tape is stuck on a surface of said main tape located in the vicinity of a winding terminating position thereof.    
     
     
         2 . The roll according to    claim 1   , wherein a width of said first adhesive tape is equal to a width of said main tape.  
     
     
         3 . The roll according to    claim 1   , wherein a desired item is printed on said print layer.  
     
     
         4 . The roll according to    claim 1   , wherein a first hole is formed in the vicinity of said winding terminating position of said main tape, said first adhesive tape being stuck over said first hole, and 
 wherein a adhesive layer of said first adhesive tape is stuck, through said first hole, on the surface of said main tape located under said main tape at said winding terminating position.    
     
     
         5 . The roll according to    claim 1   , further comprising a core, said main tape being wound up around said core, 
 wherein a second hole is formed in a winding initiating position of said main tape,    a second adhesive tape having an adhesive layer is stuck on a surface of a portion of said main tape where said second hole is located, and    the adhesive layer of said second adhesive tape exposed in said second hole is stuck on said core.    
     
     
         6 . A roll comprising a core and a main tape wound up around said core, wherein a second hole is formed in a winding initiating position of the main tape, 
 a second adhesive tape having an adhesive layer is stuck on a surface of said main tape where said second hole is located, and    the adhesive layer of said second adhesive tape exposed in said second hole is stuck on said core.    
     
     
         7 . A roll production apparatus for producing a roll by cutting a wide main film along its running direction while running the main film to produce a plurality of narrow main tapes, and by winding each main tape around a core, the apparatus comprising: 
 a perforator for opening a hole in said main film; and    an adhesive film sending-out unit for sending an adhesive film having an adhesive layer to a surface of said main film located in the vicinity of a position where said hole has been opened,    the apparatus being constituted so as to stick said adhesive film on said main film over said hole, followed by cutting said adhesive film together with said main film along its running direction.    
     
     
         8 . The roll production apparatus according to    claim 7   , wherein said adhesive film sending-out unit is a printer constituted so as to print desired information on the surface of said adhesive film.  
     
     
         9 . The roll production apparatus according to    claim 8   , wherein said printer is constituted so as to print said information on said adhesive film, followed by sending said adhesive film in a direction the same as the running direction of said main film.  
     
     
         10 . The roll production apparatus according to    claim 9   , wherein the apparatus is constituted so that said adhesive film is printed with said information, followed by being stuck on said main film running.  
     
     
         11 . The roll production apparatus according to    claim 8   , wherein said printer is disposed so as to print said information on said adhesive film, followed by sending said adhesive film in the direction approximately right angle to the running direction of said main film.  
     
     
         12 . A process for producing a roll comprising cutting a wide main film along its running direction while running it in the direction perpendicular to its width, thereby producing a plurality of narrow main tapes, followed by winding each cut main tape to produce a roll, the process comprising the steps of: 
 sending an adhesive film from a roll comprising the adhesive film wound;    printing a desired item on a surface of said adhesive film;    arranging said adhesive film on a surface of a portion of said main film where the portion becomes a winding terminating position of said main tape;    sticking said adhesive film on a surface of said main film;    moving said adhesive film and said main film together along their running direction; and    cutting said adhesive film together with said main film.    
     
     
         13 . The process for producing a roll according to    claim 12   , wherein a hole is formed in said main film and said adhesive film is thereafter stuck over said hole.  
     
     
         14 . The process for producing a roll according to    claim 12   , wherein said adhesive film is sent in the direction along the running direction of said main film and is stuck on a surface of said main film.  
     
     
         15 . The process for producing a roll according to    claim 12   , wherein said adhesive film is sent in the direction perpendicular to the running direction of said main film and is stuck on a surface of said main film.  
     
     
         16 . A process for producing a roll comprising cutting a wide main film along its running direction while running it in the direction perpendicular to its width, thereby producing a plurality of narrow main tapes, followed by winding each cut main tape to produce a roll, the process comprising the steps of: 
 sending an adhesive film from a roll comprising the adhesive film wound;    printing a desired item on a surface of said adhesive film;    arranging said adhesive film on a surface of a portion of said main film where the portion becomes a winding initiating position of said main tape;    sticking said adhesive film on a surface of a core.    
     
     
         17 . The process for producing a roll according to    claim 16   , wherein a hole is formed in said main film and said adhesive film is thereafter stuck over said hole.
