The present invention provides a slat band chain for both straight and curved lines and a sprocket made of synthetic resin which the chain can engage with every other tooth of the sprocket. At least three reinforcement ribs 24a-24c connecting the front curled portions 14 with the rear curled portions 16 are installed. The width B, and the length C, of the rear curled portions in the feeding direction are set to the intermediate value of those conventional slat band chains for straight and curved lines.
