The present invention can be applied to the above-described embodiments, it is of course also possible to apply the following various embodiments.

First, the method of gluing the edge of the panel by the edge gluing device of the panel according to the present invention will be described in general.

First, the upper and lower surfaces of the adhesive sheet are cut to fit the dimensions, and the cut panel 10 is put on a conveyor belt (not shown) of the edge bending device.

Simultaneously with release, a release agent is applied along the upper and lower edges of the cut panel.

Referring to FIG. 2 (a), the release agent 30 is applied along the edges to the upper surface 12 and the lower surface 15 of the panel 10 to facilitate removal of the cured adhesive PUR in a later process.

The release agent 30 is a releasing agent containing an ethyl alcohol component, and when a curable adhesive PUR (Polyurethane Reactive Resin), which is an adhesive, is applied to the edge surface 20, the edge surface is exposed up and down and the extra PUR is exposed to the panel ( It adheres to the upper and lower surfaces (12, 15) of 10) and is cured, but a release agent is applied in advance to remove it later.

Next, the adhesive PUR is applied to the edge surfaces 20 vertically adjacent to the upper and lower surfaces 12 and 15 of the panel, and the adhesive is applied so as to be exposed to the upper and lower surfaces perpendicular to the edge surfaces.

Referring to FIG. 2 (b), the application of the adhesive PUR to the edge surface 20 of the panel is applied to the bond roller while the bond roller 40 applied to the surface of the PUR rotates and contacts the edge surface of the transferred panel.
