Abstract:
A compressible separator system for packaging yarn spools, comprising:a top plate having face-down support plugs, a bottom plate having face-up support plugs and at least one middle plate having face-up and face-down support plugs and;the plates made of single molding construction by plastic forming and the support plugs adapted to secure corresponding said yarn spools;the support plugs including plug caps (84, 85) having respective symmetric projections in 1st and 3rd, or 2nd and 4th quadrants, the support plugs each adapted to fix and support a paper tube core of wound yarn;the plug caps in the 1st and 3rd, or the 2nd and 4th are corner-wise symmetric such that in the absence of any other items such as the yarn spools or the tube cores between the plates, the plug caps between the top plate and the middle plate, between at least two said middle plates, between the middle plate and the bottom plate, or between the top plate and the bottom plate may be inserted into corresponding open quadrants of one another to form a rigidly stacked structure;the plates having bores (6) and configured so that a layer of auxiliary corrugated carton sheet with bores corresponding to the bores of the plates and having a larger diameter than that of the tube cores can be secured on each of the plates by fasteners extendable through the bores of the plates and the sheet;the plates having at least two sides equidistant from a centerline (8); anddefensive walls extending from the sides of the plates and arranged to reduce any sliding motion of the corrugated carton sheet on the plate.
