BEST MODE FOR CARRYING OUT THE INVENTION The present inventors apply a DC voltage to only a glass plate on which a conductive film is not formed or a glass plate with a conductive film in advance, and then spray resin powder. When the posture is changed from the horizontal direction to the vertical direction, the powder almost drops when the adhesion to the glass plate or conductive film is weak, but the resin powder is sprayed only on the glass plate on which the conductive film is not formed. After that, if a DC voltage is applied and then the powder is charged, the adhesion of the powder is still weak and the powder almost falls, but after the resin powder is sprayed on the conductive film of the glass plate with the conductive coating, the DC voltage is applied. The present invention is based on the finding that if the conditions are selected, the adhesion is strong and the powder is prevented from falling even when the posture is changed from a horizontal state to a vertical state.

If the particle size is smaller than 150 μm, there is a possibility that the size of the chips (small glass pieces) remaining on the surface of the glass sheet is smaller than that of the chips. Easier to do. Further, if the particle size is larger than 350 μm, the ratio of falling particularly when the glass plate is leaned vertically increases, so that the particle size is 150 μm.
It is more preferable to set the range to 350 μm.

[0013] In order to charge the glass plate, a glass plate on which a resin powder has been sprayed in advance on a conductive film is transported by a transport device.
A charging device installed in the transport path applies a DC voltage, preferably in a range of 10 KV to 20 KV, to perform charging. In this case, when the applied voltage is less than 10 KV, the resin powder is not sufficiently charged, and when the glass plate is leaned from a horizontal state, a large amount of the resin powder falls. In particular, a spark is generated in the vicinity of the end face of the glass plate surface and damages the conductive film. Therefore, the applied voltage is in the range of 10 KV to 20 KV, particularly 15 KV to 18 KV.
Is preferable.
