ABSTRACT:
A plastic spool for receiving, storing and dispensing wire and cable is formed of multiple pieces. A preferred design is assembled in two halves, each having a tube portion and a flange portion. The tube portions have stepped, mating diameters. The tube portion of one half is stepped on the inside diameter and the tube portion of the other half is stepped on the outside diameter to match. The spool may be assembled in three pieces. The halves or pieces may be bonded together, such as by spin welding, hot plate welding, ultrasonic welding or induction welding. In some embodiments, the pieces may be fastened mechanically. Larger spools, usually referred to as reels may be configured to receive a tube into a channel formed in each flange. The channel wall may extend outboard of the inside flange wall, permitting a penetrating fastener to secure the tube to the channel wall without making any blemish or bump which might damage wire in the wrapping region around the tube between the flanges.
