Abstract
Disclosed is a single facer for producing a single-faced corrugated paperboard. The single facer comprises a first corrugating roll pivotally rotatably supported at axially opposite ends thereof; a second corrugating roll pivotally rotatably supported at axially opposite ends thereof through respective bearing units, and disposed in opposed relation to the first corrugating roll; a gluing roll disposed in opposed relation to the first corrugating roll; a parallelism inspection apparatus for inspecting parallelism between the first corrugating roll and the second corrugating roll. The parallelism inspection apparatus comprises: an actuating section for moving the bearing units of the second corrugating roll; and a detecting section provided in the actuating section to detect values of a physical quantity transmitted, respectively, from the bearing units, wherein the parallelism inspection apparatus, based on the detected values of the physical quantity, detects the parallelism between the first corrugating roll and the second corrugating roll.
