METHOD OF SUPPLYING SLIDE FRAME BLANKS TO A TRANSPARENCY MOUNTING DEVICE AND SLIDE FRAME BLANK ASSEMBLIES FOR USE THEREIN

摘要

ABSTRACTA method of continuously supplying slide frame blanksto a transparency mounting device, comprising the steps of:forming multiple lengths of the frame blanks into fan-foldedlayers, joining one length of the fan-folded frame blanksto another so that the joined lengths are connected in series,and supplying the thus joined lengths to the mounting device incontinuous form. The invention also includes a frame blankassembly for use with this method, the assembly comprising aslide frame blank assembly for use in a transparency mounting.device, the assembly comprising a plurality of slide frame blanksjoined edgewise in series and fan-folded into layers at regularintervals so as to form a regular stack of jointed adjacentlengths of frame blanks.
