ABSTRACT:
A spool barrel has flat sides which preferably are tapered from one end to the other. Rounded corners are formed between adjacent side edges. Each of the corners has a plurality of wire receiving ridges whereby the first or base layer of wire windings on the spool will nest in the grooves or channels between the ridges and be held thereby against axial movement on the spool barrel. A molded spool barrel having an integral molded lower flange has a molded upper flange removably attached to the upper barrel end.
