ABSTRACT:
A method for cleaving thin rods of glass or quartz with a rod cleaving blade (27) and body (28) carrying the blade, is provided. The body (28) is of material varying in length through application of electric and/or magnetic fields. Driving force (31, 33) achieves relatively steady movement of the blade (27) towards a desired cleaving point and relatively steady small-amplitude vibratory component of movement towards and away from the cleaving point superimposed to the relatively steady movement, by influencing the body (28) electrically and/or magnetically. The blade is driven to vibrate with a frequency below 1 kHz during cleaving operation.
