The window pa~e ~or automotive vehicle according to the present invention comprises a glass sh~et G hav~
predetermined shape and dimension and provided thereon with a p~inted layer C which may be comp~ised o~ a ceramic paste. ~s particularly shown in the ~igure in connection with the polis~ing stage 7. th~ gl~ss sheet ~ has a polish~d edge E which exactly coincides with the outer ed~e of the printed la~rer C.
~ccording to the p~ese~t inve~tion, such window panes ~an be advantage~usly manufactured by a method comprisin a cleaning stage l, ~ Pri~ting stage 2. a d~lrlg sta~e 3, a tempor~ry bakl~ stage 4, a cooling stage 5, a cutting stage 6, a polishing stage 7 and a final shaping stage, not show~, which stages are carried out in the sta~ed sequence. The pa~ticul~rs of these stages are as follows.
First o~ al]., ~he cleaning stage l is to su~ject a raw glass sheet G to an i~i.tial cleaning so as to ~e~ove ~rom the glass sheet dust, deb~ls or the ~ike roreign matters attached to the s~r~aee thereof.
In the s~ccessive printlng st~ge 2, assu~ing that the wlndow pa~e is provided with ~ Peripheral masking laYer, a ceramic paste P is applied ~o ~ sur~ace of the glass sheet G by a screen printing p~ocess k~own. per se, s~h that the oute~
2S edge o~ the p~lnted layer is situatcd sli~htly outward beyond ~ predete~mined cut con~our o~ the glass ~heet G, bY an amo~n~
which may be app~ox~mately ~ mm. The ceramic paste P thus applied to the glass ~heet G is ~ied in the d~Ying st~ge 3, in a conventional m~nner.
' ~4 12/U5 17: 54 2~03 3588 8558 `J~ rr~t3~J ~ ~ vuo~ Ul~) In the tempora~ bakln~ stage 4, at least the ed~e ~egion of the ~l~ss sheet G applled ~ith the ceramic paste P is hea~ed.
By thl~, the ceramic paste P 1~ baXed onto t~e glass sheet G to form the cera~ic masking la~e~ C. The ~lass sheet G subJected to the baking ~nd formed ~ith the ~cra~ic maski~g layer C is cooled ln the cooling st~ge 5.
However, ~he baki~g st~ge 4 and ~uccessive cooling stage 5 c~n be eliminated by usln~ ~ UV-curable-tYP~ palnt which can be ~ured when exposed to ul~raviolet ray. In t~ls instance, ~t is al~o ~ossible to prevent warping Or the gl~ss sheet G ~hich may ha~e bee~ induced by the heat.
Subsequentl~, in the cutting stag~ he ~lass sheet G is reversed ~pside down so that the sur~ac~ of t~e slass sheet G
which has been formed w~th the ceramic masklng laYer C is oriented downwards. A cut line of a p~ede~ermined contou~
corresponding to the final shape and d~m~sion of the window pane is formed in the opposi~e su~ace o~ the glass sheet G, which is now oriented ~pwa~ds. The cut line may be formed ln a conventio~al manner. e.g., by usin~ a cutter or slicer S having an appropriat~ cu~ting bl~de.
In order to achieve a satis~actory cohformity of the ~ut contour of the ~lass sheet G and the outer edge of the ceramic maski~g layer C, the cut contour ls ~ligned relative to ~
~eference side o~ re~erence point of the glass shee~ G. which ~5 is same as that ~or thc printing stage 2.
The border of the glass sheet G situated outside o~ the cut line is remo~ed, e.g., by using a burner and a sna~per, ~hile preventing fo~mation o~ defects.
A water-~et-t~pe cuttin~ de~lce may ~lternatlvelY ~e used '94 12/05 17:54 ~03 3588 8558 ~ 3J`~ ~00~/013 in the cuttlnF sta~e ~. whl~h ~erves to di~ect a ~et of hi~ly pressu~ed water on to the rlass sheet G and the~eby cut it into the fl~al shape and dime~sion of the window pane.
The edge E of the glass sheet G which has been formed b~ t~e cutting st~ge 6 1~ polished in the subsequent polishing stage 7, by using a g~lnding wheel (not shownl ~aving a su~face which is coated by fine dla~ond particles.
Fina~.~y, the gla~s sheet G ~ormed wlth the ceramic masklng laYer C an~ cut into the predetermined shape and dimension is subJec-ted to a final shapl~ into a desl~ed cu~vature, there~y to co~plete the production of a window pane ~s a final product.
~t will be ~eadily app~ ted from the ~o~e~oi~g description that, i~ accordance Wi~}1 the present in~en.~ion, the printed ~aye~ ls formed on the gl~ss sheet such that the outer edge of the printed l~e~ ls situated outslde o~ the predete~mined cut contou~ of the ~lass sheet, and the glass sheet is subsequently subjected to ~u~tin~ ~nd polishing.
