Embodiments of the present method of laser cutting a laser wavelength transparent glass article comprises feeding at least one glass article to a pulsed laser assembly having at least one pulsed laser, wherein the pulsed laser defines a laser beam focal line with a length of 0.1-100 mm, the glass article being comprised of two end sections, and at least one lateral surface disposed lengthwise between the end sections. The method further comprises laser cutting at least one perforation line onto the lateral surface of the glass article while there is relative motion between the glass article and the pulsed laser and separating the glass article along the at least one perforation line to yield a laser cut glass article.

The present invention relates to a waste fluorescent light end-cutting device. The waste fluorescent light end-cutting device includes a conveyor transferring a waste fluorescent light, a heating wire disposed on each of both sides of the conveyor, a cooling wire subsequently disposed on a rear side of the heating wire, and a suction duct disposed between the cooling wire and the heating wire. A base cap is separated from the waste fluorescent light by using a temperature difference between the heating wire and the cooling wire.

A cleaving assembly and a method for cleaving a glass body having a face at a desired angle greater than 0 degrees are disclosed. The assembly comprises a laser device for emitting a laser beam, a rotating device, and a positioning fixture. The rotating device has a head that rotates about a central axis that is orthogonal to the laser beam. The positioning fixture is operatively mounted to the head and centered axially along the central axis and is also rotatably driven by the rotating device. The positioning fixture has a tapered surface that is transverse to the central axis and that supports the glass body at a predetermined angle relative to the central axis. Rotation of the positioning fixture about the central axis when the glass body is exposed to the laser beam, cleaves the face of the glass body at the desired angle due to the glass body being supported transverse to the central axis.

A tip for being attached to a wrapper containing a smokable substance. The tip includes a tube having a generally cylindrical shape, having two ends each forming an opening at opposite ends of said tube. The openings are fluidly connected to each other by a chamber between the two ends, the chamber and said two ends being axially aligned. A first one of the two ends has a t-shaped opening and a second one of the two ends has a circular opening. The second end has an outside diameter less than an outside diameter of the first end. A method for making the tip is also described.

A method for the separative processing of brittle-hard materials is provided. The method includes irradiating a surface of a workpiece made of brittle-hard material with a laser beam having a wavelength sufficient so that light of the laser beam is absorbed at the surface and so that the workpiece is heated to create a first temperature gradient in a direction from the surface to an interior of the workpiece; guiding the laser beam over the surface along an irradiated region; forming a second temperature gradient along the surface between the irradiated region and a non-irradiated region adjacent the irradiated region, the first and second temperature gradients interacting in such a way that, on account of thermomechanical stresses, the workpiece is separated below the surface with a portion of the workpiece being severed in the form of a chip.

A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100 C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.
