Problems solved by technology
Although this disadvantage can be eliminated by setting the processing pressure of the cutting tool 3 lower, when the processing pressure is set lower, the cutting line 4 cannot be processed to a predetermined depth, so there is a problem in the subsequent breaking process. The problem of poor cutting shape occurs in

Embodiment Construction
[0027] Hereinafter, preferred embodiments of the glass ribbon slitting processing device and the glass ribbon slitting processing method of the present invention will be described based on the drawings.
[0028] figure 1 It is a cross-sectional view of the glass plate manufacturing facility 12 for manufacturing a glass plate by the float method to which the cutting wire processing apparatus 10 of the glass ribbon of this invention is applied. In addition, in the following description, the downstream side refers to figure 1 The moving direction of the glass ribbon 14 as a reference and the same direction side as the moving direction ( figure 1 The direction of the arrow X), the opposite direction side is called the upstream side.
[0029] figure 1 The illustrated glass sheet manufacturing facility 12 is provided with a float bath 20, a tin bath box 22, a slow cooling furnace 24, and a cut wire processing device 10 from the upstream side to the downstream side.

A splitting line working device for a glass ribbon comprises a plurality of conveying rollers which convey the glass ribbon and are disposed in the direction orthogonal to the glass ribbon conveying direction, and a cutting tool for working a splitting line in the direction orthogonal to the glass ribbon conveying direction on the upper surface of the glass ribbon by pressing the upper surface ofthe glass ribbon against the glass ribbon during the conveying and moving diagonally. The conveying rollers are divided at least in the range where the cutting tool is diagonally moved. A traveling path for the backup rollers of the cutting tool which are brought into contact with the lower surface of the glass ribbon is formed between the divided conveying rollers. The backup rollers are run together with the cutting tool along the traveling path by a running means at the same speed and in the same direction as the cutting tool.
Description
Technical field [0001] The present invention relates to a cut line processing device and a cut line processing method of a glass ribbon for processing a cut line glass ribbon on a belt-shaped glass ribbon that is continuously transported from a slow cooling furnace by a float process. Background technique [0002] For glass plates such as flat glass for construction, flat glass for automobiles, and flat glass for displays, a method of manufacturing a glass ribbon by a float method using a float bath has been known. [0003] The method of manufacturing flat glass by the float method is as follows: the molten glass is supplied to the surface of the molten tin in the float bath, the molten glass is shaped into a continuous sheet on the molten tin bath, and the predetermined width is placed in the molten tin bath The continuous high-temperature glass ribbon is taken out from the surface of the molten tin, and the glass ribbon is slowly cooled by a slow cooling furnace, and then the rib...
