Method of making fiberscopes with trimmed tips
Abstract
Abstract FIBERSCOPES FORMED OF A MULTIPLICITY OF ACCURATELY SUPERIMPOSED CIRCULAR FIBER RIBBONS. A PORTION OF THE LENGTH OF EACH RIBBON IS COATED IN ONE ZONE WITH A MATERIAL OF HIGH GLASS-BONDING STRENGTH AND WITH A STRIP OF AN ADHESIVE PARTING AGENT AT EACH SIDE OF THE HIGH STRENGTH BONDING MATERIAL. THE COATED PORTIONS ARE ACCURATELY SUPERIMPOSED AND CURED AT AN ELEVATED TEMPERATURE TO PRODUCE A HIGH STRENGTH BOND CENTRALLY OF THE COATED PORTIONS THROUGH WHICH A CUT IS MADE TO FORM OPPOSITE ENDS OF THE FIBERSCOPE. THESE ENDS ARE CUT, GROUND, SAWED OR CORE DRILLED PARTIALLY INTO ADJOINING AREAS OF THE ADHESIVE PARTING AGENT TO PROVIDE THE FIBERSCOPE WITH TIPS OF A DESIRED SHAPE AND SIZE WHEREUPON TRIMMING OF THE REMAINING LENGTH OF THE FIBERSCOPE TO A CORRESPONDING SHAPE AND SIZE IS AFFECTED BY DELAMINATION.
