Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.

The present disclosure relates to methods and apparatuses for printing and drying inks on substrates. Printing systems may include a metering device positioned between a printing station and a light source. During operation, the printing station deposits ink onto a substrate to define a printed region. And the light source directs infrared light onto the substrate to define an illumination zone. The printed region is advanced from the printing station to the metering device and from the metering device through the illumination zone, wherein the ink is dried with infrared light traveling from the light source, which also heats the substrate and changes the modulus of elasticity of the substrate. In turn, the metering device isolates the printing station from the change in the modulus of elasticity to help reduce phase shifts caused by changes in the modulus of elasticity resulting from heat in the substrate.

A method of manufacturing a glass roll includes separating unnecessary portions from a glass ribbon by cutting the glass ribbon along a longitudinal direction while conveying the glass ribbon. The method also includes passing the glass ribbon, from which the unnecessary portions are separated, through a looseness conveyance region on a conveyance path where the glass ribbon is loosened, and taking up the glass ribbon around a roll core at a downstream end of the conveyance path. A suction conveyor is provided between the looseness conveyance region and the downstream end on the conveyance path. While the glass ribbon is conveyed by the suction conveyor, the glass ribbon is tensioned between the suction conveyor and the downstream end on the conveyance path along with taking up the glass ribbon around the roll core.
