Abstract:
A method of laminating boards by a medium of adhesive, said method comprising:placing a first board and a second board face to face such that a narrow gap is defined between opposing faces of the first and second boards;inserting an adhesive injection nozzle into the gap;discharging adhesive from the adhesive injection nozzle into the gap so that the discharged adhesive makes contact with the opposing faces of the first and second boards while a distance between the boards is r.sub.1 +r.sub.2 *(0.2 through 0.6) where r.sub.1 is an outer diameter of the adhesive injection nozzle and r.sub.2 is an inner diameter of the nozzle;rotating the boards about a center of rotation as the adhesive is discharged so that the adhesive is placed in the gap,wherein the adhesive discharge nozzle starts to discharge the adhesive at a position in a range of 30% to 70% of a radius of the board from a center of the board such that the adhesive is placed in a loop having a start point and an end point that is shifted in a radial direction of the boards with respect the start point;retracting the nozzle from the gap; andnarrowing the gap between the first and second boards so that the placed adhesive is spread throughout the gap.
