Abstract (en)
A wire spool comprising three structural components including two end flanges (14) and a rigid fiberboard barrel (16). The end flanges (14) may be molded plastic or stamped sheet metal. The end flanges have central plug portions (18) that are mechanically locked into the barrel (16). The central plug portions include teeth (28) which dig into the barrel (16) to substantially permanently secure the end flanges (14) to the barrel such that the wire spool has sufficient strength to allow electricians to pick up a fully loaded wire spool by the end flange and such that the end flanges cannot typically be removed by hand except with the assistance of leverage tools. The plug portion (18) also may include elongate axially extending lugs (34) that engage the barrel (16) and enhance torque transfer between the barrel and the end flanges. <IMAGE>
