Claims
- 1. The method of producing a wound strand package comprising advancing the strand into an enclosure, winding the strand into a package within the enclosure, enlarging the enclosure as the package increases in size, and heating the package in the enclosure during winding of the package.
- 2. The method according to claim 1 including heating the package within the enclosure by radiant heat.
- 3. The method of producing a package of roving from a plurality of substantially dry glass strands withdrawn from strand packages wherein the strands are coated with a heat-treatable material including the steps of advancing the strands from the strand packages, gathering the strands into a linear bundle, advancing the bundle into a substantially closed chamber, winding the bundle into a package within the chamber, enlarging the chamber as the package increases in size, and heating the interior of the chamber during winding of the package to cause the coating to cohere the strands of the bundle together to form a united strand roving.
- 4. The method according to claim 3 including engaging the bundle prior to winding of the bundle with surfaces orienting the bundle into ribbon-like configuration.
- 5. The method according to claim 3 including heating the interior of the chamber by radiant heat.
- 6. The method according to claim 5 including modifying the position of the source of radiant heat as the package increases in size.
- 7. The method of producing a package of roving from a plurality of substantially dry glass strands withdrawn from strand packages mounted on a creel wherein the strands are coated with a material capable of cohering the strands together including advancing the glass strands from the strand packages, combining the individual strands into a linear bundle, advancing the bundle into an enclosure, winding the bundle into a package within the enclosure, radiantly heating the interior of the enclosure, enlarging the enclosure as the package increases in size, and reflecting heat by the interior surfaces of the enclosure to establish a temperature within the enclosure effective to cause the coating to cohere the strands of the bundle together so that upon cooling of the package a united strand bundle can be removed therefrom.
- 8. Apparatus for producing a wound strand package comprising an enclosure, rotatable means for winding the strand into a package within the enclosure, a relatively movable wall of the enclosure mounted for automated movement to enlarge the enclosure as the package increases in size, and means for heating the package within the enclosure at it is being wound.
- 9. The apparatus according to claim 8 wherein a portion of the interior surface area of the enclosure is lined with a heat-reflecting material.
- 10. Apparatus according to claim 8 wherein the heating means comprises a radiant heater disposed within the enclosure.
- 11. The apparatus according to claim 10 wherein the radiant heater is movable within the enclosure.
- 12. Apparatus for producing a roving package comprising means for supplying glass strands bearing a coating material capable of cohering the strands together, means for combining the glass strands into a linear bundle, means providing a walled chamber, rotatable mandrel means within the chamber for winding the bundle of strands into a package, radiant heating means for heating the package within the chamber as the package is being wound, a relatively movable wall of said chamber mounted for automated movement to enlarge the chamber as the package increases in size, the radiant heat within the chamber being sufficient to cause the coating to cohere the strands of the bundle together.
- 13. The apparatus according to claim 12 including means for mounting the radiant heating means on the movable wall.
- 14. The apparatus according to claim 12 including traverse means mounted by the movable wall for traversing the bundle of strands lengthwise of the package.
- 15. The apparatus according to claim 12 including means responsive to the enlarging package for effecting relative movement of the movable wall.
