ABSTRACT:
A method of, and apparatus for, the continuous supply of elongate material, for example label-carrying webs, are provided. The method comprises feeding the material from a first reel thereof of predetermined initial inner and outer diameters to an expanded reel having an inner diameter greater than that initial outer diameter, replacing a spent first reel with a second reel of the same initial dimensions within the expanded reel and joining the trailing end of the expanded reel to the leading end of the second reel. The apparatus for performing this method comprises rotatably drivable inner and outer coaxial, coplanar discs within a stationary cylindrical wall. The first reel is placed on the inner disc and is driven therewith. The material is fed from the first reel to an expanded reel formed on the inside of the wall and then out of an aperture in that wall, the expanded reel providing an accumulation of material so that splicing of the ends can be performed without stopping the feed of material from the apparatus.
