ABSTRACT:
The present invention is used for making repairs to a laminated glass having a layer with a damaged area. A drill and bit are used to make a drilled hole at the damaged area of the glass. A large vacuum cup which is standard for handling large sections of glass is attached to the glass and the pump and handle of the cup is used to support a bridge with a swivel nut in position to receive an injector. The injector is connected to a hand pump which is first operated to clear the window of debris by providing a high vacuum pressure. The hand pump is also used to evacuate air from the injector before a repair resin is injected into the drilled hole at the damaged area. The hand pump has a mode valve to produce a pressurizing cycle to provide an injection pressure of 30 to 35 psi. The high injection pressure forces the resin into the drilled hole to penetrate the damaged area and repair the glass. Curing of the resin is achieved by exposing the resin to Ultra-Violet light by using a U-V patch and/or a U-V curing lamp.
