<p>PURPOSE:To correct the curl of a blank under some satisfactory condition by preventing a film member from being affected by wear, stain or the like. CONSTITUTION:A curl correcting device 10 disposed in a blank transporting path 5 has a film member 20 disposed between roll members of an elastic roll member 11, and a metal roll member 12 is pressed against these members by a solenoid 15 so that a curling action is given to a blank in the opposite direction to the curl direction. Also, a taking-up means is provided for the film member 20. When an accumulated value of detecting information of a sensor S reaches a predetermined value, a controller 40 generates a drive signal to a motor driving circuit 42 to take up a predetermined length of the film member and press the new film surface corresponding to the metal roll member against the blank.</p> |
