Methods of laser processing a transparent material are disclosed. The method may include positioning the transparent material on a carrier and transmitting a laser beam through the transparent material, where the laser beam may be incident on a side of the transparent material opposite the carrier. The transparent material may be substantially transparent to the laser beam and the carrier may include a support base and a laser disruption element. The laser disruption element may disrupt the laser beam transmitted through the transparent material such that the laser beam may not have sufficient intensity below the laser disruption element to damage the support base.

The present invention relates to a cutting method and a cutting device for the superficial scoring of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, and to a method for dividing of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, for example of float glass sheets or laminated glass sheets, in particular laminated safety glass sheets, into individual component cuttings, preferably glass sheet cuttings.

A method of cutting a combined structure of a glass substrate and a light absorbing plate includes providing a glass substrate on a metal plate, providing a light absorbing material at an edge of the glass substrate, and cutting the glass substrate and the light absorbing plate by irradiating a laser beam to the glass substrate from the edge to which the light absorbing material is provided.

A device for press-cutting glass, a method for press-cutting glass, and a glass-cutting system having the device for press-cutting glass. The device for press-cutting glass comprises a supporting member, having a first supporting portion and a second supporting portion for supporting a glass substrate, which are arranged in a spaced apart manner in a first direction; and a press-cutting member for press-cutting an edge of the glass substrate, which is positioned between the first supporting portion and the second supporting portion in the first direction. The device for press-cutting glass has advantages including high press-cutting efficiency, simple structure, low manufacturing cost, and easy assembling with other devices.

The present invention concerns a method of determination of specific points of a rotary fibre forming spinner wheel (10) used in a fibre forming device (1), said method comprising the following steps: obtaining measurements of temperatures of the fibre forming spinner wheel obtained by means of a temperature measuring device (40) adapted to take measurements of temperatures of the spinner wheel at a plurality of angular positions of said measuring device in order to supply data to at least one calculation unit (30, 45) that constructs a curve representing the temperature as a function of the angular position of a temperature measuring device; processing said measurements by effecting a calculation of the second derivative of the curve of the temperature as a function of the angular position by means of a calculation unit (30); searching for at least one specific point for which the second derivative satisfies a predefined condition.

A glass bottle cutter based on electric heating comprises a base. A rotary bracket and a heating and cutting seat are disposed at two ends of an upper surface of the base respectively. A motor is disposed in the rotary bracket, and a rotating shaft of the motor is disposed outside the rotary bracket and is provided with a support plate. An adhesive pad allowing the bottom of a glass bottle to cling thereto is disposed on a surface of the support plate. A heating tube is disposed on an upper surface of the heating and cutting seat. The base is provided with a power access port and an internal circuit mainboard. The motor, the heating tube and the power access port are all electrically connected to the circuit mainboard.

Provided is a method of producing a glass roll 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). The cutting step includes a step of winding a thread-like peeled material (Ge) generated from an end portion of the product portion (Gd) in a width direction around a rod-shaped collecting member (23), and leading the wound thread-like peeled material (Ge) in a predetermined conveying direction (PX) by a leading device (24).
