Abstract
A wound coil of an elastic material is formed by feeding a monofilament of elastic material over a winding coil of a coiling head onto a mandrel to form a coil. A pair of conveyors are located on opposite sides of the coil on the mandrel and define therebetween a stabilizing zone for moving the coil along the mandrel through such zone while heating and thereby stabilizing the coil. The conveyors include respective heating elements located on opposite sides of the coil and respective planar members formed of a heat transmitting material and between which the coil is fed along the mandrel. Each planar member is in contact with the coil and a respective heating element.

An apparatus for producing a wound coil of an elastic material such as a polyester or polyamide which stabilizes upon the application of heat, said apparatus comprising:
- a coiling head including a winding cone having extending therefrom a mandrel, whereby a monofilament of elastic material may be fed over said winding cone onto said mandrel to form a coil;
- a pair of conveyor means, located on opposite sides of said coil on said mandrel, and defining therebetween a stabilizing zone for moving said coil along said mandrel through said stabilizing zone while heating and thereby stabilizing said coil;
- said mandrel extending throughout said stabilizing zone;
- said conveyor means including respective heating elements located on opposite sides of said coil;
- and
- said conveyor means further including respective planar members formed of a heat transmitting material and between which said coil is fed along said mandrel, each said planar member being in contact with said coil and a respective said heating element, thereby transmitting heat from said heating element to said coil.
