Glass roll and method of processing glass roll

Abstract

A roll-to-roll apparatus reliably reduces breakage of a glass film even in a case of sequentially performing predetermined processing on the glass film. Provided is a glass roll ( 1 ) formed by winding a glass film ( 2 ) into a roll, in which a resin film ( 4 ) is attached onto the glass film ( 2 ), and at least a part of the resin film ( 4 ) is arranged on a front side of an unwinding direction relative to a leading end portion in the unwinding direction of the glass film ( 2 ).

1 . A glass roll, which is formed by winding a glass film into a roll,
 wherein a resin film is attached onto the glass film, and at least a part of the resin film is arranged on a front side of an unwinding direction relative to a leading end portion in the unwinding direction of the glass film.   
     
     
         2 . The glass roll according to  claim 1 , wherein the resin film is coupled to the leading end portion in the unwinding direction of the glass film. 
     
     
         3 . The glass roll according to  claim 2 ,
 wherein the resin film is coupled also to a trailing end portion in the unwinding direction of the glass film, and   wherein at least a part of the resin film is arranged on a rear side of the unwinding direction relative to the trailing end portion in the unwinding direction of the glass film.   
     
     
         4 . The glass roll according to  claim 2 , wherein the glass film and the resin film are coupled to each other with an elastic member. 
     
     
         5 . The glass roll according to  claim 4 , wherein the elastic member couples a region including a widthwise center line of the glass film and a widthwise center line of the resin film. 
     
     
         6 . The glass roll according to  claim 2 , wherein the glass film and the resin film are coupled to each other under a state in which an end portion of the resin film is superposed on an end portion of the glass film. 
     
     
         7 . The glass roll according to  claim 1 , wherein the resin film longer in length than the glass film is superposed and attached onto one surface of the glass film, and the resin film is extended beyond the leading end portion in the unwinding direction of the glass film. 
     
     
         8 . The glass roll according to  claim 7 , wherein the resin film is extended also beyond a trailing end portion side in the unwinding direction of the glass film. 
     
     
         9 . The glass roll according to  claim 7 ,
 wherein the glass film comprises a plurality of glass films, and   wherein the plurality of glass films are attached onto the same resin film.   
     
     
         10 . The glass roll according to  claim 7 , wherein the resin film is superposed and attached onto the one surface of the glass film, and an another resin film separate from the resin film is superposed and attached onto another surface of the glass film. 
     
     
         11 . A processing method for a glass roll, for sequentially performing, by a roll-to-roll apparatus, predetermined processing on a glass roll including a glass film wound into a roll, the processing method comprising:
 attaching a resin film onto the glass film;   arranging at least a part of the resin film on a front side of an unwinding direction relative to a leading end portion in the unwinding direction of the glass film; and   guiding the glass film into the roll-to-roll apparatus while the resin film is in the lead.   
     
     
         12 . The processing method for a glass roll according to  claim 11 , wherein a length of the resin film, which corresponds to a part on the front side of the unwinding direction relative to the leading end portion in the unwinding direction of the glass film, is equal to or larger than an entire length of a conveyance path for the glass film in the roll-to-roll apparatus. 
     
     
         13 . The processing method for a glass roll according to  claim 11 , wherein at least a part of the resin film is arranged also on a rear side of the unwinding direction relative to a trailing end portion in the unwinding direction of the glass film. 
     
     
         14 . The processing method for a glass roll according to  claim 13 , wherein a length of the resin film, which corresponds to a part on the rear side of the unwinding direction relative to the trailing end portion in the unwinding direction of the glass film, is equal to or larger than the entire length of the conveyance path for the glass film in the roll-to-roll apparatus. 
     
     
         15 . The glass roll according to  claim 3 , wherein the glass film and the resin film are coupled to each other with an elastic member. 
     
     
         16 . The glass roll according to  claim 15 , wherein the elastic member couples a region including a widthwise center line of the glass film and a widthwise center line of the resin film. 
     
     
         17 . The glass roll according to  claim 3 , wherein the glass film and the resin film are coupled to each other under a state in which an end portion of the resin film is superposed on an end portion of the glass film. 
     
     
         18 . The glass roll according to  claim 4 , wherein the glass film and the resin film are coupled to each other under a state in which an end portion of the resin film is superposed on an end portion of the glass film. 
     
     
         19 . The glass roll according to  claim 5 , wherein the glass film and the resin film are coupled to each other under a state in which an end portion of the resin film is superposed on an end portion of the glass film. 
     
     
         20 . The glass roll according to  claim 15 , wherein the glass film and the resin film are coupled to each other under a state in which an end portion of the resin film is superposed on an end portion of the glass film.
