When precise alignment is obtained, the first air supply is cut off to lock the air slides in the position of alignment. A recess in end portions of the top plate has air holes communicating therewith which are supplied from air from a second source. The flow of air from this second source is continuous and is sufficient to prevent foreign material from entering the air slide.

Abstract: Cutting strengthened glass by means of a high velocity fluid jet. A suitable fluid is placed under high pressure and directed against the surface of the glass in a highly collimated stream of small diameter at high velocity. Very fine abrasive particles are aspirated into the high velocity stream prior to its impingement upon the glass to serve as a cutting medium for the strengthened glass. The pressure of the fluid is reduced when starting the cut to avoid venting of the glass during initial penetration, and the pressure is then increased for movement of the fluid jet along the desired line of cut. The relationship between fluid pressure, line speed and abrasive grit size is carefully controlled to produce a smooth cut free from vents and chips so as to avoid failure of the strengthened unit.
