Abstract: A method of conveying a glass film composite uses a roll-to-roll process for winding a glass film composite wound on a feed roller by a winding roller through a plurality of conveyance rollers. The glass film composite includes an elongated glass film, and linear resin tapes disposed on one side of the glass film along a longitudinal direction of the glass film at both ends in a width direction of the glass film. The method includes a step of conveying the glass film composite from the feed roller to the winding roller through the plurality of conveyance rollers without passing a state in which the glass film composite is bent so that the resin tapes are directed to the inside.

Abstract: A method is disclosed for dividing a composite material 10 including a brittle material layer 1 and a resin layer 2 that are laminated together, the method includes: a resin removing step of applying laser light L1 oscillated from a CO2 laser light source 20 to the resin layer along a planned division line DL of the composite material, so that a processed groove 24 is formed along the planned division line; and a brittle material removing step of applying, after the resin removing step, laser light L2 oscillated from an ultrashort pulsed laser light source 30 to the brittle material layer along the planned division line, so that processed marks 11 are formed along the planned division line. The processed marks formed in the brittle material removing step open on the resin layer side and do not penetrate through the brittle material layer.

Abstract: Provided is a production method for a film laminate by which a tough film can be bonded to a brittle film while the breakage of the brittle film is prevented. The production method for a film laminate of the present invention includes bonding a tough film having an elongated shape to a brittle film having an elongated shape while conveying the brittle film, wherein the method includes bonding the tough film and the brittle film to each other by bringing the tough film close to the brittle film, followed by blowing of a gas from a side of the tough film opposite to the brittle film.
