Method and device for separating a rod-like or tubular object made of a brittle material
Original language description
The invention relates to a method for separating a rod-like or tubular object made of a brittle material, particularly glass, in which at first at least one circumferential notch is made on the surface of the object in a predetermined position, whereupon the fixed object is acted on by a force pulse or force pulses. The force pulse is applied in the direction of the longitudinal axis of the object to be separated to produce a longitudinal stress wave propagating through the object in the direction of its longitudinal axis, the stress wave being reflected from the free end of the separated object in the form of a tensile wave which in the region weakened by the circumferential notch closest to the free end of the object causes separation of the portion of the tube. In addition, the invention relates to a device for performing this method.
