Packaging coils of wire or cable on reels

摘要

In forming a coil package (4), a blank of cardboard is folded to form a closable carton having a pair of parallel oppositely disposed major side walls (5), each of which has an aperture (6) in axial alignment with the aperture of the other major side wall; a coil of wire (7) is fed into the carton until it bounds the apertures in the major side walls; a hollow hub (1) having longitudinally extending corrugations (2) and preferably made of metal is arranged to extend between and protrude beyond the major side walls and is expanded radially outwardly, e.g. by a mandrel, until it fits tightly in the apertures in the major side walls and its cross section has become substantially circular; and the protruding end parts of the hub are distorted so that they form flanges (8) that bear against the outer surfaces of the major side walls (5). Preferably, during distortion the major side walls (5) are forced inwardly to a dish-like shape so that no part of the hub protrudes beyond the planes containing the boundary edges of the major side walls, so allowing stacking.
