Abstract

DEVICE AND METHOD FOR OPERATION IN AN HELICAL PATTERN INSIDE A CYLINDER A DEVICE AND METHOD FOR PERFORMING AN OPERATION ALONG AN HELICAL PATH ON THE INSIDE SURFACE OF A HOLLOW CYLINDRICAL ROLL FROM ONE END OF THE ROLL TOWARD THE OTHER END, THE DEVICE COM PRISING:a) A CARRIAGE SUPPORTED ON A PLURALITY OF WHEELS HAVING AXES ORIENTED IN A DIRECTION GENERALLY PARALLEL TO THE AXIS OF A ROLL UPON WHICH AN OPERATION IS TO BE PERFORMED:b) THE CARRIAGE HAVING A SUPPORT BRACKET ADJUSTABLY SECURED THEREON WITH FIRST MEMBERS FOR ADJUSTING THE BRACKET IN A DIRECTION GENERALLY PARALLEL TO THE AXES OF THE WHEELS; (c) A TOOL HELD IN A CLAMP SUPPORTED BY THE BRACKET FOR PERFORMING AN OPERATION ON THE INSIDE SURFACE OF A ROLL; ANDd) FOLLOWER MEMBER EXTENDING GENERALLY IN A PORTION OF AN HELICAL PATTERN ON THE UNDERSIDE OF THE CARRIAGE FOR COOPERATION WITH A GUIDE ELEMENT TO MAINTAIN THE TOOL OPERATING ALONG AN HELICAL PATH OF THE ROLL RECEIVING AN OPERATION FROM THE TOOL. THE METHOD COMPRISES THE STEPS OF:a) SUPPORTING A ROLL FOR ROTATION WITH ITS AXIS EXTENDING IN A GENERALLY HORIZONTAL DIRECTION;b) SUPPORTING A TOOL ASSEMBLY ON THE INSIDE SURFACE OF THE ROLL WITH ROTATABLE SUPPORTS IN A MANNER TO PERMIT ROLLING MOVE MENT OF THE SUPPORTS WHEN THE ROLL IS TURNED BUT ALSO CONSTRAINING THE SUPPORTS AND THE TOOL ASSEMBLY TO MOVE IN THE PATH OF AN HELI CAL PATTERN FROM ONE END OF THE ROLL TO THE OTHER AS THE ROLL IS TURNED; (c) PROVIDING THE TOOL ASSEMBLY WITH A TOOL EXTENDING IN POSITION TO PERFORM AN OPERATION ON THE INSIDE SURFACE OF THE ROLL: ANDd) TURNING THE ROLL AT A SLOW RATE OF ROTATION WHEREBY THE TOOL ASSEMBLY WILL MOVE ACROSS THE INSIDE SURFACE ALONG AN HELICAL PATTERN WITH THE TOOL THEREOF PERFORMING AN OPERATION ON THE INSIDE SURFACE OF THE ROLL ALONG AN HELICAL PATTERN.
