Abstract
In a manufacturing method of a glass roll, a transport device transports a glass film coupled to lead films via coupling portions. The transport device separates the lead films and/or the coupling portions from a heating roller when the lead films and/or the coupling portions pass by the heating roller.
Claims9
A manufacturing method of a glass roll, the manufacturing method comprising:
- forming a functional film on a glass film transported by a transport device while heating the glass film in a state where the glass film is in contact with a heating roller;
- and
- winding the glass film on which the functional film is formed into a roll shape,
- wherein the glass film is coupled to a lead film via a coupling portion, and
- the transport device is configured to separate the lead film and/or the coupling portion from the heating roller when the lead film and/or the coupling portion pass by the heating roller.
A manufacturing device for a glass roll, the manufacturing device comprising:
- a transport device configured to transport a glass film coupled to a lead film via a coupling portion;
- and
- a heating film formation device configured to form a functional film on the glass film,
- wherein the heating film formation device includes a heating roller configured to come into contact with and heat the glass film, and
- the transport device includes
- an unwinding device configured to feed out the glass film,
- a winding device configured to wind the glass film on which the functional film is formed into a roll shape,
- a transport roller disposed between the unwinding device and the winding device and configured to transport the glass film, and
- a separation member configured to separate the lead film and/or the coupling portion from the heating roller when the lead film and/or the coupling portion pass by the heating roller.
