Abstract
To provide a single facer glue application adjusting method and apparatus which enable 1 to prevent occurrence of defective sheet accompanying with operation mistake like negligence of setting change of roll gap in a change of papers, 2 to improve appearance of corrugated board sheet and to enhance quality of strength etc. of same and 3 to decrease manufacturing cost of a glue application adjusting apparatus. A glue application roll 1 rotating at a circumferential velocity v.sub.1 different from that v.sub.2 of a downstream side corrugating roll (an upper corrugating roll) 9 is moved to touch the downstream side corrugating roll 9 via a core paper 11 and, upon variation in the circumferential velocity of each said roll caused thereby, a setting position of the glue application roll 1 to the downstream side corrugating roll 9 is adjusted, thus a gap between the glue application roll 1 and the downstream side corrugating roll 9 is maintained approximately at a thickness of the core paper 11.
