in accordance with the prior art , fig1 shows a schematic diagram , describing a traditional production of coating windshields with edge deletion or deletion windows . in the schematic diagram of fig1 , a set of coated glass sheets ( step a ), are cut in different sizes ( short and long sheets ) ( step b ). after the coating is removed from the long sheets , in areas previously selected or edge deletion areas ( step c ), to permit the transmission of electro magnetic fields commonly used in the transmission of signals ( radio , gps , garage door openers , tv , toll road cards , etc ), these areas are commonly named “ deletion windows ” which act as access ports for all those electromagnetic signals and in case of the edge deletion , they seal the reflective coat from the effect of the atmospheric elements . the problems which arise when removing the coating from a glass sheet to form the “ deletion windows ” have been widely described in the prior art . in step d , the edge of the glass sheets are finished ( seaming or grinding ) according to the product specifications . in step e , the cut and edge finished glasses are washed on a regular production washer machine . after the short and long sheets are separated and the short sheet ( step f ) is decorated in some areas , with a ceramic frit layer , for example , to protect the adhesive that bonds the glass to the vehicle from the ultraviolet rays of the sun , to hide electrical wires and other hardware behind the glass , and also to provide a filter for the amount of sunlight allowed into the vehicle such as “ half tones ” on the moon roof and certain backlites . meanwhile , in step g , a release or departing agent ( i . e . a separating power ) is applied to the long sheet to provide a temporary protection for a surface , as well as an interleaving material for protection and separation of adjacent surfaces . in the step h , the short and long sheets are formed in pairs . in step i , the glass sheets are subjected to a bending process to provide a curvature for use , e . g ., in an automobile window . in step j , the glass sheets are washed before the assembly . in step k , two pieces of glass with a layer of polyvinyl butyral ( pvb ), which is provided in step l , are encased therebetween to form a windshield . in this step k , a vacuum process is applied to hold the pvb layer in place between the glass sheets to remove air bubbles . thereafter , the glass sheets are put into an oven called an autoclave ( step m ) which heats the assembled windshield . the entire setup reaches 135 ° c . to 145 ° c ., thereby melting the pvb , making it transparent , and fusing the three layers into one . the quality of lamination , or adhesiveness between the pvb and the glass sheets , are dependent on the temperature within the autoclave and the effectiveness of the pressure on the glass sheets and pvb . once the product has been assembled , the glass product is shipped to a customer location ( step n ) for sale . now making reference to fig2 to 7 , the method and system to produce coated automotive glass with “ deletion windows ” in accordance with the present invention will now be described . referring now to fig2 , the schematic diagram of the method steps in relation with the system for the processing coated glass substrate with edge deletion or deletion windows or both comprises the following steps : a set of non - coated glass sheets ( step 10 ) are cut in different sizes ( short and long sheets ) ( step 12 ). in step 14 , the edge of the short and long glass sheets are finished ( seaming or grinding ) according to the product specifications . in step 16 , the cut and edge finished glasses are washed on a regular production washer machine . thereafter , the short and long sheets are separated , the short sheet ( step 18 ) is decorated in some areas , with a ceramic frit layer , for example , to protect the adhesive that bonds the glass to the vehicle from the ultraviolet rays of the sun , to hide electrical wires and other hardware behind the glass , and also to provide a filter for the amount of sunlight allowed into the vehicle , such as “ half tones ” on the moon roof and certain backlites , which is similar to step f in fig1 . meanwhile , in step 20 , the long sheet ( b ) is printed with an enamel , to print “ the deletion windows ” over the long glass sheet ( b ). the enamel is applied by means of a screen printing device to apply the enamel on predetermined regions to said glass sheet or substrate . the printing device applies the enamel using a serigraphic method and , after drying the paint , using a regular ir or uv curing oven . the painted area ( a ) in fig4 , is identical as the deletion edge or “ deletion windows ” and can be easily modified using a new printing screen . the most commonly used “ deletion windows ” in a windshield gs ( fig3 ) are the traffic control vics device ( i ); rain sensor , line departure camera , garage door opener ( ii ); toll gate prepaid card ( iii ); gps , satellite radio ( iv ); and edge deletion to avoid metallic coat oxidation ( v ). in step 22 , the glass sheet ( b ) with the painted area ( a ) now passes through regular production equipment like infrared , convective or ultraviolet drying oven , to dry out all the enamel solvents , normally using a temperature in a range of 150 ° c . to 250 ° c . for a residence time such as 10 to 20 minutes . thereafter , the long sheet ( b ) with the painted area ( a ) will be pre - washed and loaded into a coating line ( coater ) co , which is a schematic shown in fig5 , to apply a multi layer metallic coating film ( c ) over the side of the glass that creates the reflective properties . the coated glass ( b ) will now be heated in an infrared oven ( ir ) or convective oven to a temperature in a range from 280 ° c . to 550 ° c . over sufficient time , most of the time being between 5 to 15 minutes to carbonize the applied enamel . this action allows time to remove the enamel ( step 24 in fig2 ) to glass bonding preparing it for a later removal . in step 26 , a release or departing agent ( i . e . a separating power ) is applied to the long glass sheet ( b ) to provide a temporary protection for a surface , as well as an interleaving material for protection and separation of adjacent surfaces . in the step 28 , the short and long sheets are formed in pairs . in step 30 , the glass sheets are subjected to a bending process to provide a curvature for use , e . g ., in an automobile window . in step 32 , the short and long glass sheets are loaded onto a glass washer equipment wm ( fig7 ) where by means of the high pressure water nozzles and the use of some auxiliary mechanical cleaning device , for instance brushes , the carbonized enamel ( a ), now in the form of ashes ( d ) will be cleaned from the glass surface ( b ) together with the coat deposited ( c ) applied over said enamel ( a ). the action of removing the enamel ashes and the inherent coating , will leave as a consequence “ non - coated areas ” on the glass surface identical in form and size to the desired “ deletion windows ”. the control of the form and size of the deletion window is dependant on the customer design which is translated onto a printing screen which is used on the printing machine to print the image on the glass . finally , the bending and washed glass sheets are now being assembled in pairs , including a layer of polyvinyl butyral ( pvb ) 36 between the same to form a windshield ( step 34 ). thereafter , the glass sheets are put inside an oven called an autoclave ( step 38 ) which heats the vacuumed windshield , as was previously described . once the product has been assembled , the glass product is shipped to a customer location ( step 40 ) for sale . the present invention has been described in an illustrative manner . it is to be understood , that the terminology that has been used , is intended to be in the nature of words of description rather than of limitation . many modifications and variations of the present invention are possible in light of the above teachings . therefore , the present invention may be practiced other than as specifically described .
