Abstract: The invention relates to an unit tile pack manufacturing apparatus. The apparatus comprises a tile pack conveying passage (8) for conveying a plurality of pallets (9), a combination tile pack forming unit (100), a joint alignment correcting unit (15), an adhesive dropping unit (30), and a connecting sheet supplying and pressing unit (45). These units (100, 15, 30 and 45) are disposed along the tile pack conveying passage (8). In the combination tile pack forming unit (100) a plurality of tiles of different tones of the same color or a plurality of tiles of different color are arranged side by side in lines and rows. The adhesive dropping unit (30) includes adhesive dropping nozzles (35) disposed at a predetermined interval from the tiles and intermittently dropping an adhesive on the upper surface of each of the tiles at positions close to the side adjacent to corresponding positions of the adjacent tiles.
