PROBLEM TO BE SOLVED: To solve a problem that a resin for jointing unit tiles spreads on the bottom surface of the tiles in a unit tile production line. SOLUTION: In a middle part of a transportation line 2 circulating continuously a plurality of joint boards 1, 1a... having notch parts 7, 7a... formed on projections 6, 6a... forming joints between recess parts 4, 4a... for storing a plurality of tiles, a discharging device 3 for for a thermoplastic resin type adhesive agent is provided. Nozzles 22, 22a... for discharging the adhesive agent are provided on the sites corresponding to the notch parts 7, 7a... of the joint boards 1, 1a... in the lower part of a discharging body 12 of the discharging device 3 for a thermoplastic resin type adhesive agent. A heating device 23 for the tiles T, Ta... and the joint boards 1, 1a... is provided at the upstream site of the discharging device 3 for the adhesive agent and a cooling device 25 for the tiles T, Ta..., the adhesive agent and the joint boards 1, 1a... is provided at the downstream site of the discharging device 3 for the adhesive agent. The adhesive agent is filled in the notch parts 7, 7a... of the joint boards 1, 1a... reaching a position under the discharging body 12 so that the adhesive agent is not spread on the bottom surface of the tiles T, Ta....
