In a roller to affect a temperature of a print substrate in a digital printer, a hollow roll is mounted to a shaft. Channels are provided for a heat transport medium in the hollow wall. A roller shell of the hollow roll is comprised of arc-shaped segments extending over a width of the hollow roll. The segments end laterally in arms designed so that the arms of adjacent segments are connected to each other. The channels extend over the width of the hollow roll and are assembled respectively from the segments of the roller shell. A respective covering plate is clamped between the arms of the respective segments. |
