Device, useful for cutting float glass ribbon with normal or structured surface, comprises bottom and upper slide rails, back pressure rollers, suppression with crushing roller and device for measuring pre-running speed of glass ribbon

摘要

Device comprises: (a) a bottom slide rail (3) with a cutting slide for a lower section at a structured surface and an upper slide rail (5) with a cutting slide for an upper section at normal surface; (b) a number of back pressure rollers (8) for the lower cutting slide (4); (c) a suppression with a crushing roller and a front suppression roller for the lower section; (d) a suppression with a crushing roller and a back suppression roller for the upper section; and (e) device for measuring the pre-running speed of the glass ribbon and its actual length. Device comprises: (a) a bottom slide rail (3) with a cutting slide for a lower section at a structured surface and an upper slide rail (5) with a cutting slide for an upper section at normal surface, where both slide rails are in an acute angle and are arranged obliquely with respect to the sliding direction of a glass ribbon (11) and the inclination is adjustable; (b) a number of back pressure rollers (8) for the lower cutting slide (4); (c) a suppression with a crushing roller and a front suppression roller for the lower section; (d) a suppression with a crushing roller and a back suppression roller for the upper section; and (e) device for measuring the pre-running speed of the glass ribbon and its actual length. Independent claims are also included for: (1) cutting a float glass ribbon with normal or structured surface, comprising providing a plant for producing normal float glass or float glass with a structured surface, which includes the bottom slide rail with cutting slide for lower section at a structured surface and an upper slide rail with the cutting slide for the upper section at normal surface, providing the components (b), (c), (d), and (e), detecting the structure of the surface of the cut ends of float glass ribbon by sensors, crushing a suppression with a crushing roller and a back suppression roller in the presence of unstructured glass at the desired point of the float glass ribbon, and crushing the suppression with the crushing roller and a suppression roller in the presence of structured glass at the desired point of the float glass ribbon; (2) a computer program having a program code for carrying out the above mentioned method, when the program is performed in a computer; and (3) a machine readable carrier with the program code of the computer program for carrying out the above mentioned method, when the program is performed in a computer.
