In a method for producing a structured seed layer for carbon nanotubes to be deposited thereon, energy is applied by means of a laser beam to a metal layer previously applied to a substrate such that the metal layer is broken up into individual islands. The laser beam is expanded into a beam having a linear cross-section, and a linear exposure zone of the metal layer is simultaneously exposed to the expanded beam. The exposure zone is moved across the metal layer in a direction transverse to the length of the exposure zone. An apparatus for carrying out the method comprises a device for transporting a substrate with a metal layer applied thereto, a laser to produce a laser beam, and a device for expanding the laser beam to produce a linear exposure zone that extends perpendicularly to the direction in which the substrate is transported.

Provided is method of producing a glass roll, the method including: a conveying step of conveying a glass film (G) along a longitudinal direction thereof; a cutting step of irradiating the glass film (G) with a laser beam (L) from a laser irradiation apparatus (19) while conveying the glass film (G) by the conveying step, to thereby separate the glass film (G) into a non-product portion (Gc) and a product portion (Gd); and a take-up step of taking up the product portion (Gd) into a roll shape, to thereby form a glass roll (R).
