Abstract
The object of the invention is to simplify the production of woven, endless tire reinforcing belts by enabling rapid, economical changes in belt size and simplified removal of the belts from the weaving apparatus. The invention provides a method and apparatus for forming reinforcing belts which meet this objective by employing an endless weaving surface comprised of a flexible belt supported by means rotatable about spaced, parallel axes. By moving the supports apart, the weaving surface is tensioned for the weaving operation; and, by moving the supports toward one another, the weaving surface is relaxed to permit removal of the woven reinforcing belt. The circumference of successive reinforcing belts can easily be changed by changing the flexible belt comprising the weaving surface.
