A folding apparatus for use on a cartoning machine which folds and secures the end flaps of a blank to form a carton including a pivoting rocker arm positioned adjacent to the path of said carton movement and a fold blade pivotedly attached to one end of said rocker arm which engages the flap and moves it into contact with the side of the carton. A device for manipulating said rocker arm is provided so that the fold blade will engage and disengage the flap and a yieldable means associated with said fold blade to apply a selected pressure to said flap with a roller assembly for engaging the fold blade and control the pressure applied by said yieldable means.
