METHOD FOR SEALING EDGE PORTION OF DOUBLE-LAYER PRODUCT AND DEVICE FOR SEALING EDGE PORTION OF DOUBLE-LAYER PRODUCT

摘要

A reliable countermeasure against the infiltration of moisture through an edge portion of a double-layer panel product such as a solar cell panel and an electronic panel for an image display device. The tip end of a coating discharge opening has a shape of a slit facing a part of the shapes of the peripheral surfaces of the longitudinal cross-sections of the edge portion of the double-layer panel product which is a work to be coated. By the rotary driving of the coating nozzle having the slit-shaped coating discharge opening, the direction of the slit-shaped coating discharge opening can be changed in a planar view, so that continuous operation is possible with respect to the edge portion of the four peripheral surfaces on the front/rear/right/left sides.
