THE APPARATUS CONSISTS OF COOPERATING SHEET RUBBING MEMBERS AND SQUEEZE ROLLERS WHICH ARE CARRIED RESPECTIVELY WITHIN THE ABOVE A CONTAINER OF SOLVENT ON FRAME SECTIONS HINGED TOGETHER ABOUT A HORIZONTAL AXIS AT THEIR LOWER ENDS. THE HINGE PERMITS THE RUBBING MEMBERS AND ROLLERS TO BE SEPARATED FOR THE ADMISSION OF THE SHEET MATERIAL AND BROUGHT TOGETHER FOR FRICTIONALLY ENGAGING THE SHEET MATERIAL ON REMOVAL THEREOF FROM THE CONTAINER BY ROTATION OF SAID SQUEEZE ROLLERS. AT LEAST ONE RUBBING MEMBER HAS A SURFACE OF POROUS RESILIENT MATERIAL FOR CONTACTING SAID RECORDING LAYER.
