PROBLEM TO BE SOLVED: To avoid a waste of material by preparing a preset set table in which a preset amount of a paper feeding means is set based on a paper quality data including a paper kind, a weighing capacity, a paper dimension and a paper eye and selecting a preset amount corresponding to an input value of the paper quality data from the table. SOLUTION: A paper quality data from a paper quality input means 30 is inputted to a preset amount set means 40 and a paper thickness is determined from a weighing capacity and a paper thickness by a paper thickness set means 39. A modulus of elasticity is determined from the weighing capacity and a modulus of elasticity by a modulus of elasticity calculation part 36. Subsequently, a rigidity is calculated from the modulus of elasticity and the paper thickness by a rigidity calculation part 37 and a rigidity parameter is calculated from the rigidity, an air density and a longitudinal dimension of paper by a rigidity parameter calculation part 38. A preset value of a separated air amount corresponding is determined by a separated air amount set table 41 to which the paper kind and the rigid parameter are inputted. Thereafter, a separated air amount sprayed from a separated air supply nozzle is set to a preset value in a separated air amount adjusting means 51. |
