PURPOSE:To prevent mis-registration between two sheet materials by constituting the title device in such a manner that the sheet material having the higher rigidity of the two sheet materials is run while said sheet is brought into contact with a stage. CONSTITUTION:The two sheet materials 65, 67 which are different in rigidity are held superposed on each other and are run in this state on the stage 7. The two sheet materials 65, 67 are brought into pressurized contact with each other by rollers 58, 58' which roll in the direction intersecting with the traveling direction of the two sheet materials and the stage 7; in addition, the device is so constituted that the sheet material 65 having the higher rigidity of the two sheet materials is run in the state of maintaining the contact with the stage. The sheet material 65 having the higher rigidity is thus brought into contact with the stage 7 at the time when said material is brought into pressurized contact with the stage by the rollers 58, 58' and, therefore, the generation of such a deformation as to accumulate the repulsive force to induce the parting between said sheet material and the sheet material 67 having the lower rigidity is obviated. The generation of the mis-registration between the two sheet materials is thereby prevented.
