Apparatus and methods for cleaning strip materials
Abstract
Abstract APPARATUS AND METHODS FOR ULTRASONICALLY CLEANING FRAGILE STRIP MATERIALS, SUCH AS MOTION PICTURE FILM AND THE LIKE. THE STRIP MATERIAL IS PASSED IN A DOUBLE RUN THROUGH A SOLVENT BATH LOCATED WITHIN THE BORE OF A GENERALLY CYLINDRICAL ELECTROMECHANICAL TRANSDUCER. A MATERIAL TRANSPORT MECHANISM, IN PART SELECTIVELY RECIPROCABLE BETWEEN A THREADING POSITION ADJACENT ONE END OF THE TRANSDUCER BORE AND A RUNNING POSITION ADJACENT THE OTHER END OF THE BORE, ALLOWS READY INTRODUCTION OF THE MATERIAL INTO THE BORE FOR CLEANING AND ALSO FACILITIES MATERIAL THREADING AND REMOVAL. THE SOLVENT BATH IS MAINTAINED WITHIN THE BORE BY IMMERSING THE TRANSDUCER IN AN EXTERNAL SOLVENT BATH OR BY ENCLOSNG ONE END OF THE TRANSDUCER BORE TO CONTAIN THE SOLVENT WITHIN THE TRANSDUCER ITSELF.
