Abstract
Description
Claims (7)
- 2. The method according to claim 1 wherein the directed heat from the heat source is radiant heat.
- 3. The method of encasing a substantially rigid tubular body of glass fibers in a heat-shrinkable tubular jacket including disposing the tubular body in a substantially horizontal position on a support, telescoping the tubular body and the jacket thereon about the axis of the tubular body, and subjecting the rotating jacket to heat from a heaT source substantially the length of the tubular body to shrink the jacket into intimate engagement with the body.
- 4. The method of encasing a substantially rigid tubular fibrous body in a tubular jacket of heat-shrinkable film including disposing the tubular body in a substantially horizontal position upon a support, telescoping the tubular film lengthwise onto the fibrous body with end regions of the tubular film extending beyond the ends of the fibrous body, applying heat by convection to the end regions of the tubular film to shrink said end regions in stressed engagement with the end regions of the body, and applying radiant heat to the portion of the film intermediate its end regions to shrink said portion in stressed engagement with the body.
- 5. The method according to claim 4 including rotating the fibrous body and the film thereon about the axis of the body during the application of heat to the film.
- 6. The method of encasing a substantially rigid tubular fibrous body having male and female end configurations in a tubular jacket of heat-shrinkable organic film including disposing the tubular body in a substantially horizontal position upon a support, telescoping a preformed tubular film lengthwise onto the fibrous body with the ends of the film extending beyond the ends of the fibrous body, applying heat by convection to the film at the male end region of the body to shrink the film at said region in engagement with the male end, applying heat by convection to the film adjacent the female end of the body to shrink the film radially inwardly embracing the female end, and applying radiant heat to the portion of the film intermediate its end regions to shrink said portion in engagement with the body throughout its periphery.
- 7. The method according to claim 6 including the step of trimming the inwardly extending portion of the film adjacent the female end of the body.
- 8. The method of encasing a substantially rigid tubular body of glass fibers in a jacket of heat-shrinkable material including disposing the tubular body in a substantially horizontal position upon a support, fitting the jacket onto the fibrous body with the end regions of the jacket extending beyond the ends of the body, rotating the body and jacket about the longitudinal axis of the body, applying heat to the end regions of the rotating jacket to shrink the said regions in stressed engagement with the end regions of the body, and applying radiant heat to the rotating jacket exteriorly of the jacket and substantially throughout its length to shrink the portion of the jacket intermediate its end regions in stressed engagement with the tubular fibrous body throughout its periphery.
