DEVICE, MACHINE AND METHOD FOR COATING A WEB-FORMAT CARRIER SUBSTRATE WITH A DRY FILM

Examples include a device for coating a web-format carrier substrate with a dry film. The device includes an application unit having first and second rollers forming a first gap therebetween. A counter-pressure roller, together with the second roller or a further roller forms a second gap through which a substrate path for the carrier substrate to be coated leads. A measuring device includes a sensor system for measuring the grammage of the dry film. A positioning drive is provided for adjusting the gap width of the first gap. The sensor system connects to a control device configured to vary the gap width of the first gap based on the grammage determined by the sensor system and via a connection to a drive means of the positioning drive, and/or to vary a ratio between the circumferential speed of the first roller and the circumferential speed of the second roller.
