Patent ID: 8875651

Claim:
A transport device for a double-sided coated substrate, comprising: a first die head for front face coating and a second die head for back face coating, the first and second die heads configured to coat a coating liquid onto front and back faces of a substrate; a drying oven for drying the coating liquid applied to the substrate, to form a coating film on the front and back faces of the substrate; and a first rotating body unit configured at a first position to grip a first widthwise edge section of the substrate and a second rotating body unit at a second position to grip a second widthwise edge section of the substrate being opposite to the first widthwise edge, an imaginary line between the first and second positions being perpendicular to a transport direction of the substrate; the first rotating body unit including a first pair of rotating bodies for gripping the first widthwise edge section of the substrate from the front and back sides, the first pair of rotating bodies having a pair of first rotating shafts, the first rotating shafts extending parallel with respect to each other, and a first rotating body swivel section that enables an orientation of the first pair of rotating bodies for the first rotating shafts to have a first incline angle with respect to the transport direction, the first rotating body swivel section rotatably supporting both of the first pair of rotating bodies about the first rotating shafts, respectively, the first rotating body swivel section swiveling both of the first pair of rotating bodies with the first rotating shafts about a first swivel axis while maintaining the first rotating shafts in parallel with respect to each other, the second rotating body unit including a second pair of rotating bodies for gripping the second widthwise edge section of the substrate from the front and back sides, the second pair of rotating bodies having a pair of second rotating shafts, the second rotating shafts extending parallel with respect to each other, and a second rotating body swivel section that enables an orientation of the second pair of rotating bodies to for the second rotating shafts to have a second incline angle with respect to the transport direction, the second rotating body swivel section rotatably supporting both of the second pair of rotating bodies about the second rotating shafts, respectively, the second rotating body swivel section swiveling both of the second pair of rotating bodies with the second rotating shafts about a second swivel axis while maintaining the second rotating shafts in parallel with respect to each other, the orientation of the first pair of rotating bodies being independent from the orientation of the second pair of rotating bodies.
