Abstract
Directly glass-cutting abnormal member and various sheet material still keep the optical quality of glass-cutting simultaneously on the heated glass strip.Pull out the float glass strip by glass forming chamber, before annealing, line of cut is heated to the softening temperature of this glass.With blade apparatus along this line of cut that heated incision separate glass thereafter.In online heating and the cutting operation process, whole glass temperature is all remained on more than the strain point of glass.
Description
The present invention relates to the cutting of sheet glass, cutting glass plate on the heated glass strip particularly, and in the sheet glass that downcuts, maintain optical quality at the same time.
The manufacturing of sheet glass or bending glassy product generally needs with the independently different operations of twice: basic working procedure and aided process.
Basic working procedure comprises from fused glass and forms the glass strip, this or this kind melten glass floated on the molten tin bath, or from a melten glass groove direct drawn glass plate.For example disclosed in people's such as Edge No. 3,843,346, the United States Patent (USP) in above-mentioned float forming operation, be melten glass is adhered to and to float on the molten tin bath to form strip.This float glass strip begins to cool down and its thickness is determined on this molten tin bath the time already.Afterwards, this glass strip is promptly left molten tin bath and is transported to the annealed zone, herein the temperature of this strip controlledly is cooled to be lower than the temperature of its strain point.In above-mentioned forming operation, the thickness of this sheet glass (for example be same as Slingluff at United States Patent (USP) 1,339, No. 229 disclosed) is to pull out from molten glass bath and determined during postcooling at it.After the annealing, this glass strip promptly is cut into sheet glass and uses for aided process thereafter.
Aided process can comprise the sheet glass procedure of processing of any a plurality of complementarities.For example, can the structural glass plate carry be cut into net shape before, be cut to sheet material littler, that be easier to dispose.This kind net shape can be the rectangle of desktop or glazing etc. and so on, perhaps also may be special windowpane structure, the more complicated shape of automotive glazing and so on.Sheet glass also can boring and/or edging and/or bend to certain angular shape after cutting forming.Boring and edging operation generally are to be in room temperature condition following time at glass to carry out.This class operation might produce tiny cracked at the edge of glass, and they may be focal point of stress, causes later cracked and destruction.In forming operation, the glass through cutting is reheated the temperature to its heat deformable, and for typical soda lime glass, this temperature is about 1150 °F to 1250 °F (621 ℃ to 677 ℃).Heating and buckling work can be with any the carrying out in the many kinds of different methods.For example, sheet glass can be transported to so-called level by process furnace and pressurizes in the crooked platform (as No. 4,197,108, people's such as Frank United States Patent (USP)) on roller; Perhaps on pressing gas bed or gas hearth through process furnace and entering in the crooked platform, sheet glass is shaped (as No. 4,204,853, the United States Patent (USP) of Seymour) with the sagging method herein; Perhaps sheet glass is carried on the curve generating cylinder, be shaped (as No. 4,139,349, people's such as Johnson United States Patent (USP)) with the roller moulding method.
Through cooling process and/or after adding thermal flexure, sheet glass can heat enhancing.Under the room temperature situation, sheet glass can be reheated certain temperature that is higher than its annealing range, promptly be cooled to its strain point with this sheet glass of tempering then through this annealing range.Under the situation of bending glass, behind buckling work, be about to sheet glass and cool off so that its tempering rapidly.
The glasswork that has satisfied optical quality now for manufacturing such as the actual practice of window, mirror or the like, need to adopt basic and auxiliary two procedures.Clearly,,, for example, reheat, also can improve finished product (for example obtaining high-quality glass edge) just reduced some steps if this basic working procedure or aided process can be improved or this two procedures can make and is merged into a procedure.So just might reduce cost widely.If this basic working procedure includes the float forming of glass strip, then after glass is drawn from molten tin bath, needn't add stretching again, grind or polishing operation, just can make it to have final thickness of glass and qualified optical quality, also will further reduce cost.

In United States Patent (USP), Corl 1,550, No. 428; 1,560, No. 077 of Gelstharp and Despret 2,243, No. 149 have all disclosed the technology that is cut to sheet glass when the glass strip during still in plastic state.Particularly, Corl has proposed 1 and by a plurality of cuttings awls the sheet glass that is disposed at has therebetween been realized " being carved into " along each big of glass strip.Gelstharp has proposed to cut this strip that still is in the plasticity attitude with the cutting wheel that is contained on the vehicle frame and can move along the throughput direction of glass strip.Despret has proposed to rotate with predetermined speed with the roller that blade is housed, and makes this glass that is in the thermal softening state of blade cuts.
People such as little Ritter are at United States Patent (USP) 3,124, have proposed a kind of method in No. 444, promptly to the glass strip in the motion when it still is in plastic state following time, remove its arris or edge section continuously.This is the arris place that the cutting blade of a pair of circle is placed in the glass strip, so that strip by the time, and the arris of this strip is cut off from remaining strip.
People such as Diaz announce in French Patent and have proposed cutting in 2 567 No. 872 still in the method for the sheet glass of plastic state.Sheet glass is by a pair of cutter that is rotating, and this cutter is almost pressed the whole thickness of sheet glass.First group of cutter radial ground is installed around cutting wheel, so as along sheet glass vertically to its continuous cutting, second group of cutter vertically installed along the length of cutting wheel, so that press lateral periodicity cutting glass plate.
No. 3,453,097, the United States Patent (USP) of Hafner, 3,543, No. 979 of people such as Grove, 3,885,943 and 3,930 of Chui, 3,935, No. 419 of people such as No. 825 and Lambert have all proposed the technology with the laser beam glass-cutting.In the patent of Hafner, selected each parameter of laser apparatus, made sheet glass can absorb laser energy and convert it into enough heats, cut into piece by to have been allowed sheet glass along this laser beam flying route.The patent of Grove has proposed cutting glass plate on the successive glass strip, generating the stressed zone in this glass, and sheet glass is controlledly split with beam of laser scanning glass plate along this sweep trace.In above-mentioned two patents of Chui, glass is gasified along line of cut with laser.At United States Patent (USP) 3,930, in No. 825, with a pair of laser beam directly from float glass strip cutting typical glass goods down.Can believe that the power of this kind laser apparatus and gasify the required time of glass with a kind of like this laser apparatus is forbidden in large-scale commercial production.
French is at United States Patent (USP) 3,934, a kind of cutting method has been proposed in No. 995, promptly after the glass strip is exported from the float glass process production line, the quenching that is subjected to control by the strip that makes part comes cooled glass, line is cooled off at indentation on glass in the edge, and promptly splits along line of weakness glass, and cuts Pork-pieces sheet glass down from the glass strip.
Giffen is at United States Patent (USP) 3, proposed a kind of forming of glass method of operation in 193, No. 367, the melten glass plate of pulling out from aquarium has been placed on the shaping die, then it is pressed in the mould and with the shear tool cutting, in the compacting operation from the sheet glass that is left separation of glasses.
Grove is at United States Patent (USP) 3,584, proposed a kind of method of glass-cutting in No. 773, promptly adopts the thickness of high-frequency dielectric heating by sheet glass, makes it controlledly to split along line of cut.
Oelke is at United States Patent (USP) 3,687, proposed a kind of method and apparatus that cuts cold sheet glass in No. 956, and the thermal source that promptly utilizes glass pane surface therewith to separate mutually heats it along desirable line of cut.Heat from a radiant heat source is restricted on the narrow path that line of cut is suitable therewith.Owing to concentrated heat, between the not heated portion of sheet glass and this extremely narrow heat affected zone, just formed very big temperature head, and the stress accumulation of this coexistence causes that just whole sheet glass splits.
Anderson is in United States Patent (USP) 4,162, proposed in No. 907 a kind of on molten tin bath the method for cutting melten glass.With an extrusion machine with the melten glass lay on molten tin bath, then cutting rack is reduced on the molten tin bath to paste firmly and decides glass, again this melten glass is cut into required size with cutting machine.During the cutting melten glass, adopt the rotating blade of air-operated drive, blade sees through glass and enters into molten tin.
People such as Anderson are at United States Patent (USP) 4,361, have proposed to be formed by the fused sheet glass method and apparatus of goods in No. 429.Melten glass is by pulling out by a pair roller in the molten bath.The melten glass plate is placed on the die cavity, makes it delivery chamber configuration by vacuum or deadweight or the two dual-purpose.When this sheet glass during, its crush-cutting is become end article still in molten state.With the vacuum type take-out this end article is taken out from mould.
Above-mentioned these patents have been announced the multiple cutting technique of glass, but do not relate to the cutting of high quality optical glass strip, this kind glass strip is fully cooled off, can be treated and do not reduce its optical quality, but still be enough hot, do not need again with glass heats so that can heat-treat (being tempering or annealing).
The objective of the invention is when glass is in can be processed and don't produce glass-cutting under the temperature of vestige, its method is that required line of cut is heated to glass remollescent temperature, that is glass-cutting can not produce vestige and cracked under this temperature, but be lower than the vaporized temperature of glass, and penetrate the glass of this thermal softening with cutting blade.
In an optimum implementation of the present invention, the glass that relates to is a continuous propulsive float glass strip.This sheet glass brings from the float forming operation, thereby final thickness of glass and required optical quality are all definite in the forming of glass process, any additional process that need not stretch, grind, polish and so on.When the glass strip was pulled out from the molten tin bath of float forming operation, it was enough hard, allowed to move and transport and do not produce vestige or other influence to optical property.In this whole cutting operation process, glass will remain in the certain temperature range, for example in its annealing region, a scope like this allows glass is moved fortune and vestige does not take place, simultaneously, glass is for further processing, and for example bending, quenching, annealing or the like do not need other heating yet.Glass is optionally reheated to its softening temperature with thermal-flame or other typical well heater along required line of cut.Line of cut can be a straight line, for example is the straight line across this go-ahead plate width, perhaps can be to limit the peripheral straight line desire glass portion branchs that downcut on the strip from then on.Well heater can be installed on the big face of this glass strip and under, and advance along the direction that this strip is carried.After line of cut is heated to required temperature, cuts sheet glass with the cutting facility that has cutters parallel and bring cut-out glass with line of cut.In cutting process, these cutters advance along the strip throughput direction.The sheet glass that cuts down is removed from progressive glass strip, and then, well heater and cutting facility turn back to the original position again.
In another embodiment of the invention, be to cut pieces of glass down from a fixed sheet glass.At least be near required line of cut glass sheet partial to be preheating to certain temperature, for example be preheating to annealing region, like this, the heat from the well heater of arranging along the line of cut direction is concentrated just can not make this sheet glass owing to thermal stresses is broken.The well heater of these arrangements makes the temperature of line of cut be elevated to the softening temperature of glass.Sheet glass can be sent to cutting bed, cuts with the blade that is parallel to the line of cut that has heated, downcuts pieces of glass; Maybe can make sheet glass keep motionless, move well heater, and cutters are shifted near sheet glass to downcut pieces of glass.Then pieces of glass is taken off from sheet glass, be transported to next station again, carry out other processing.
In another embodiment of the present invention, the fixed well heater is placed in the glass strip of advancing slightly by the inboard of its thick round edge, a pair of rotating blade is placed on the downstream of well heater, aim at well heater.When the glass strip moves forward, promptly downcut along the thick round edge of heater wire with the glass strip, after the cutting-out, thick round edge that utilizes a shift assembly to downcut is removed.

The present invention provides with regard to the situation that it is applied to cut in the soda lime float glass, but it must be understood that, the present invention can be applied in the cutting operation of any board-like material, particularly can be applied in the forming operation of any kind glass or the glass that is used for any kind is formed.
When description is of the present invention, will relate to some character and the reference temperature of glass." annealing point " and " strain point " is defined as when using ASTM(American society standard) when method C336 measures, corresponding to the ratio elongation of a glass fibre; When perhaps measuring, corresponding to the sagging ratio of a glass stick mid point with ASTM method C598.When annealing point, internal stress needs only several minutes and can eliminate basically.When strain point, internal stress will be eliminated basically with several hours ability.Temperature range between annealing point and strain point is called annealing range.Glass is in heat treatment process, and its temperature is descend lentamente (annealing) by this annealing range the time, or descend hastily (tempering).For typical soda lime float glass, the temperature of annealing point is generally in the scope of 1000 to 1040 (538 ℃ to 560 ℃), the temperature of strain point is generally in the scope of 925 to 970 (496 ℃ to 521 ℃), and annealing range is between 925 °F to 1040 °F (496 ℃ to 560 ℃)." optical quality of float glass " can its principal light transmission defective focal power be feature, this printing opacity defective is because the irregularity on surface, usually (in 1.91～5.08cm) the scope, its focal power is about the 30 milli orders of magnitude of Qu Guangdu or littler near 0.75～2 inch at wavelength.
Fig. 1 shows the situation of understanding that float glass strip G is sent by working chamber 10.Because strip G is a float glass strip, it just has good optical quality, and the many purposes can be used for needs and see through this glass and do undistorted the observation time.This successive glass strip G is that (for example from the melt metal tin bath) moved on the strip supporter 16 that comprises a gas cooker support bed 18 or additional conveying roller (not shown) by a series of roller 14 from a bath of molten metal 12, and enters in the annealing furnace (not shown).Though the present invention is to this also no standard, but above-mentioned gas furnace support bed 18 is preferably in temperature-controlled chamber 20, so that the thermosteresis in this strip is reduced to minimum, because the reason that the back will discuss, this support bed also comprises a forced ventilation system 22, it can force the upper face of the pressurized air arrival gas furnace support bed 18 of heat, forms the air cushion of a supporting hot glass.With barrier 24 atmosphere is remained in the working chamber 10.The chamber 20 of being engaged in heating and cutting operation generally is in the model degree scope of about 1080 to 1150 (582 ℃ to 621 ℃), promptly is higher than the annealing point temperature of float glass.In the float glass process, the glass strip in the said temperature scope is sufficiently rigid, get vestige not occur so that it can be transported with contacting by roller 14 and other handling equipment, thereby its optical quality can not be interfered.
Referring to Fig. 2 and Fig. 3, resting support 26 is supporting well heater 28, and this well heater is across the width of crossing strip G.The heat of high temperature guiding hot glass sheet G that well heater 28 will have been concentrated is so that promptly be heated to its softening range (back will be discussed) with selected line of cut 30.Well heater 28 can be any in the various commercially available thermal source, as long as it can provide concentrated heat and can make it along line of cut 30 guidings.Though the present invention is not limited this, in the embodiment of the best, well heater 28 is line burners, it with thermal-flame guiding and on the glass strip G selected line of cut 30.By fuel conduit 32 and oxygen pipeline 34(and nonessential), be provided with to producing the necessary combustion gases of thermal-flame to burner 28.The well heater of resistance-type heater, high-frequency dielectric well heater, plasma torch heats device, laser heater or electron-beam heater and so on all can adopt.
Aim at the static line 30 on the translational surface of strip G for the flame that makes burner 28,, burner 28 can be moved with the speed identical with strip G for aforementioned resting support 26 has disposed a drive unit 36.Motion available computers 37 controls that resting support 26 borrows drive arrangements 36 to carry out.This resting support 26 moves to along the direction of strip G line of cut 30 is heated to softening range after the required time, promptly comes back to its zero position.Before next bar line of cut 30 moves on to well heater 28 or at the same time, this drive unit 36 must be with being enough to make well heater 28 re-position at this well heater 28 of speed drive of its zero position.Though the present invention is not stipulated this, as the drive unit 36 that is shown in the particular embodiment among Fig. 1,2 and 3, can comprise one by axle 42 electric motor 38 that link to each other with drive sprocket 40.Sprocket wheel 40 and tooth bar 44 engagements, the latter is connected with sliding shaft sleeve 46 on being installed in slide rail 48.Prop up and take advantage of frame 26 by sliding shaft sleeve 46 supportings.50 on post provides supporting for slide rail 48 and motor 38.For mobile resting support 26, available motor 38 drives sprocket wheels 40 and rotates, and the latter drives tooth bar 44 again or motion backward forward, that is left as shown in Figure 1 or right route along slide rail 48 defineds moves.
Must recognize that line of cut 30 can be heated to higher temperature, however like this will be with bigger power and/or than long time heating glass.In addition, if glass is heated to too high temperature, it just may deform, and the result will damage the optical property of final glasswork.
Because line well heater 28 and 52 is to assemble heat along a herring bone of sheet glass, thus thermal shocking might take place in glass, that is the stress that glass may not necessarily have time enough that high temperature is produced is down gone therein again and is distributed, thereby causes breaking of glass.For fear of this kind situation, the sheet glass that cut should be heated to its strain point temperature at least and preferably reach or be higher than its annealing point temperature, concentrates any internal stress that produces so that discharge by heat, does not make glass fragmentation faced.Do not need the monolithic glass plate all is raised to high like this temperature, and only need this sheet glass is got final product in line of cut contiguous part or the intensification of reheat district.The width in this reheat district depends on Several Factors, for example the feature of heating system; The chemical constitution of glass; The strain point of glass, annealing point and softening point temperature; And the temperature rise rate of hot-zone again.When sheet glass to be cut directly from the strip forming process send or when this sheet glass for crooked and when heating once more, the temperature of whole sheet glass all is higher than annealing point, so that sheet glass is the reheat district that discharges internal stress effectively on its whole width.When just the part of sheet glass was reheated, this reheat district must be sufficiently wide, to redistribute by well heater 28 and 52 any thermal stresses that causes.
After selected line of cut 30 in the hot-zone again is heated to the temperature of its thermal softening, and when the rest part of this sheet glass still was in soaking condition, a promptly available strip cutting unit 56 cut the strip G of heat along line of cut 30.Strip shut-off device 56 be with one or several blades carry out work along the line of cut 30 that is heated by glass strip G.In the illustrated the present invention's of Fig. 1 and 2 particular embodiment, this shut-off device 56 is installed on the resting support 26, include a blade 58 that is positioned on the strip G and is parallel to heater wire, and one is positioned under the blade 58 face and parallel with it pedestal 60 and the glass strip is passed through therebetween.Pedestal 60 is installed in the slot of gas furnace support bed 18.If needed, the temperature of blade 58 and/or pedestal 60 can be controlled, and makes their enough heat so that sheet glass can not cool down before cutting; But can not be overheated, in case sheet glass be sticking thereon.
In order to cut off glass strip G, resting support 26 progressive speed will reduce a little, so that the line of cut 30 of preheating is between blade 58 and pedestal 60.When this line of cut was between blade 58 and pedestal 60, resting support 26 recovered its initial speed of advance again again, did not have relative movement in order that make between strip G and the resting support 26.After this, blade 58 promptly moves down and/or makes pedestal 60 to move up, and cuts off glass strip G along pre-hot line 30.Blade 58 and/or pedestal 60 can be for vertical movement by any mode easily, for example, by means of hydraulic pressure, air operated, electronic drive unit (not shown) or by itself dead weight (for blade).In the embodiment of the best, as shown in Figure 4, pedestal 60 comprises a groove 62.The edge 64 of groove 62 plays the effect of second blade, and the glass strip G that moves through of blade enters groove 62, finishes cutting process.Also can have a firm surface 66 by aforementioned as shown in Figure 5 pedestal 60, be able to must be pointed out that finishing glass cutting under 66 situations about contacting blade 58 does not need fully to cut sheet glass with blade 58 glass-cuttings and with the surface.Can make blade 58 cut the big half thickness of sheet glass, stop to will contact pedestal 60 time.Afterwards, when strip is cooled off slightly, can sheet glass G can be separated by simple bending or " breaking off with the fingers and thumb disconnected " measure from remaining glass strip.
Though in optimum implementation of the present invention, do not cut off when operation has relative movement between resting support 26 and strip G and carry out, but it must be understood that, if the cutting action of blade 58, still can allow some relative movement rapidly to being enough to cut off glass and don't causing any additional optical skew.
In order to raise the efficiency, blade 58 should be heat-stable and not react with glass.In addition, blade 58 preferably should be able to keep a sharp-pointed blade, so that reduce the maintenance of blade, for example, sharpening and/or replacing again.The high-strength material of stainless steel and so on can be used as this blade and pedestal.
In cutting off operation process, blade 58 and pedestal 60 are to move along the direction that strip G moves.After the cut-out operation is finished, as shown in Figure 1, blade 58 and/or pedestal 60 promptly return, resting support 26 then moves to the left side, and the glass under cutting has been got back to its original position when remaining sheet glass G transports out of out, for example (but not stipulating in the present invention) can make the support bed 18 of gas furnace downward-sloping, leaves working chamber 10, so that the part of cutting off is removed from remaining glass strip G.In addition, can mix the wheel (not shown) with the transfer roller that drives the sheet glass that cuts off is transported out of progressive glass strip.Moreover, sheet glass can be used on the vacuum pick device (not shown) on top and transports, and when sheet glass G was in chamber 20, this pick-up held its upper face, if necessary, can make it travel to and fro between different treatment process sections and carry out thereafter processing such as bending, treating selvedge, heat enhancing, annealing.
Fig. 6 illustrates another kind of heating and shut-off device.With device among Fig. 1 relatively, the structure has here adopted and has independently heated and cut off frame.The resting support 68 of well heater is supporting a upper portion heater 70(if needed, and a lower heater 72 is set in the line of rabbet joint of coal gas bed support bed 18 again), it is across glass strip G, and slides along the throughput direction of strip G.When strip G after line of cut 30 is heated, when gas furnace support bed 18 moved continuously, resting support 68 promptly was moved back into the original position at strip G.When the line of cut of preheating arrived cutting unit 76, cutting frame 78 just moved in the line of rabbet joint 80 with strip G.And work as in the strip G cutting frame at the volley to timing, just with similar approach cut-out discussed above.Other device is equipped with in order to adjust well heater resting support 68 independently and to cut off frame 78.
Shown in Fig. 1 and Fig. 6, the maximum unsupported length of glass strip G will be line of rabbet joint 54(Fig. 1 in the gas furnace support bed 18) width, or the line of rabbet joint 74 or 80(Fig. 6) width.
Above just the described operation degree of Fig. 1 can be in improvement, reducing the desired width of the line of rabbet joint 54, thereby reduced the maximum non-bearing length of glass strip G.Particularly, available computers 37 starts drive units 36, promotes resting support 26 and advances along strip G, makes burner 28 and 52 that line of cut 30 is heated to the softening temperature of strip simultaneously.After the heating, be not that the speed of advance that slows down resting support 26 makes strip G advance with respect to this resting support 26, but by computer 37 reverse resting support 26 the progressive direction and make it moving at a high speed to working chamber 10, that is, as shown in Figure 1, be moved to the left.When resting support 26 has turned back to certain position, when making line of cut 30 be between blade 58 and the pedestal 60, its reverse again its direction and begin to move forward, that is as shown in Figure 1, G moves right along strip, so that there is not relative movement therebetween.This kind operational procedure has reduced the required combined stroke of resting support 26, and makes the width of the line of rabbet joint 54 reduce to minimum.
The present invention relates to the sheet glass strip that is moving is cut and still kept its optical quality with regard to the content that it disclosed, particularly when cutting off the float glass strip and still keep the optical quality of its float glass.Obviously similarly the line heating also can be applicable to the immobilized flat glass plate with the cut-out technology; Equally, this cutting of sheet glass or strip is not to be only limited to along straight cuts yet, but can cut along curve or successive loop wire within the periphery of sheet glass or strip shown in Fig. 7 and 8.
When individual sheet glass of cutting, must meet such temperature distribution, promptly the line well heater is supplied with adds heat and will be can cause break (discussing as preceding) because of hot line and the temperature head around it.
If sheet glass cooled off before cutting, then this sheet glass at least will be in the adjacent area of line of cut in addition preheating.If sheet glass is directly from the forming of glass operation, the then original just preheating of monolithic glass plate will not be so when other has concentrated heat to guide to sheet glass, it will can break.In optimum implementation of the present invention, the temperature of sheet glass is the temperature in its cutting zone at least, minimumly should reach its strain point temperature and preferably will equal or exceed ANNEALING OF GLASS point temperature.High like this temperature can maintain in whole line heating and cutting operation with the following methods, promptly finishes these operations in a warmed-up cavity, with limit heat losses.Must be pointed out, if make bending glass sheet and before cutting, it be heated to its flexure temperature, this flexure temperature is 1050 °F to 1200 °F (566 ℃ to 649 ℃) for typical soda lime float glass for example, and then whole glass will be in the above temperature of annealing point.In the particular embodiment of the present invention shown in Fig. 7,8 and 9, the sheet glass G of preheating is at heating location 82 places, along selected line of cut 84, carry out the line heating by the annular burner 86 on top and the annular burner 88 of bottom, until the softening point temperature that is heated to it.Then sheet glass G is transported to cutting position 90, and, according to the mode that discussed the front, for example goes to cut off, to form cutting part 94 with shut-off device 92 along the above-mentioned line that this has heated.Transporting between heating location 82 and cutting position 90, available any mode is easily finished, for example (but be not qualification for this reason) can be on a downward-sloping gas furnace support bed 96 that is shown in Fig. 7, by the roller (not shown) of transfer roller, or transport sheet glass by vacuum pick device (not shown).Can sheet glass G be fixed on heating location 82 and the cutting position 90 with brake component 98 and 100.Another kind method is well heater and shut-off device to be debouched on the desired position, and allow sheet glass G all keep stationary state in heating and the cutting operation.
