Roll production apparatus

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 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.    
   
   
       2 . The roll production apparatus according to  claim 1 , wherein said adhesive film sending-out unit is a printer constituted so as to print desired information on the surface of said adhesive film.  
   
   
       3 . The roll production apparatus according to  claim 2 , 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.  
   
   
       4 . The roll production apparatus according to  claim 3 , wherein the apparatus is constituted so that said adhesive film is printed with said information, followed by being stuck on said main film running.  
   
   
       5 . The roll production apparatus according to  claim 2 , 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.
