Belt meandering preventing system in single facer

A belt meandering preventing system in a single facer consisting of an upper fluted roll having flutes formed on the circumference thereof;

• a lower fluted roll, also having on the circumference thereof flutes which are engaged with those of said upper fluted roll to form a predetermined corrugation on a corrugating medium passed between said upper fluted roll and said lower fluted roll;
• a gluing mechanism for gluing the crests of corrugation in said corrugating medium;
• and an application mechanism which is disposed adjacent to said lower fluted roll and equipped with an endless belt extended over a plurality of rolls so as to be able to run freely thereby;
• in which a liner is pressed against the glued crests of corrugation of said corrugating medium fed along the circumference of said lower fluted roll to be pasted with said corrugating medium and form a single-faced corrugated board;
• characterized in that a support shaft on which one of said plurality of rolls is rotatably fitted is designed to be swung on one end portion thereof as a fulcrum by operating a drive means.
