Retractile cords disposed in a U-shaped configuration are arranged about the periphery of a turntable with the ends of each cord adjacent to the peripheral edge being terminated with modular plugs. As a cord having its ends terminated with modular plugs is moved into a last work station, a pickup arm removes the cord. As the plug-ends are moved outwardly from the turntable, a middle section of the U-shaped cord is engaged by a snagging pin that is moved into one portion of a foldable tray to hold the middle section of the cord as the plug ends are moved farther along above the tray. The plugs are released, and the cord retracts and drops into the tray. Then the snagging pin is retracted, and the tray is caused to be folded to form an opening beween portions of the tray. The cord descends through the opening into an open end of a bag formed between two plies of a plastic material. The plies are bonded together adjacent to the open end and the bag is separated from its supply. For longer length cords, the movement of the plug ends is discontinued when they are in the other tray portion. As a result, when the tray is folded, the cord is doubled over prior to its movement into the bag.

DETAILED DESCRIPTION The foregoing needs have been met by the methods and apparatus of this invention.
In a method of this invention, a retractile cord is transferred from a conveyor to an apparatus where it is packaged in a container.
The retractile cord is positioned on a conveyor and is moved through a plurality of work stations whereat the ends of the cord are terminated with modular plugs.
Each terminated end of the cord is grasped and forces are applied to pull the cord from the conveyor with the cord being in a U-shaped configuration.
As this is done, a middle portion of the cord length is intercepted by a snagging pin.
Movement of the plug ends is continued to extend the helices of the cord and to cause the cord to be aligned with a foldable tray.
The plug ends are released whereupon the cord retracts and becomes disposed in the tray.
The snagging pin is retracted to release the middle portion of the cord after which the tray is folded to form an opening in the lower end of the tray which is aligned with an open end of the container.
The released cord descends under its weight through the opening in the tray and is received in the container.
The folding of the tray serves to propel the cord into the container.
An apparatus for packaging cords which have been terminated at their ends with plugs as the cords are advanced through a plurality of work stations on a conveyor includes a pickup arm for grasping the plug-terminated ends of each cord.
The pickup arm is moved outwardly from the conveyor to pull the cord from the conveyor.
As this is done, a snagging pin intercepts the middle portion of the cord.
The pickup arm continues to move to cause the helices of the cord to be extended.
Then the pickup arm releases the ends of the cord whereupon the cord retracts and becomes disposed in a foldable tray comprising two hinged portions.
A short cord in an extended condition is disposed in one portion of the foldable tray.
On the other hand, a long cord is disposed across both portions of the tray
