Abstract
A method of making a wire braid shrouded annularly corrugated metal tube. An annularly corrugated metal tube is formed. A braided wire shroud is placed around the annularly corrugated metal tube. The braided wire shroud is deformed into a corrugation valley of the annularly corrugated metal tube so that the shroud conforms to the adjacent peaks and the intervening valley. The annularly corrugated metal tube and the braided wire shroud are severed at a desired location between the corrugation peaks. The shroud is then bonded to the tube adjacent the end of the shrouded tube.
Claims13
A method of making a wire braid shrouded annularly corrugated metal tube comprising:
- a. forming an annularly corrugated metal tube with the corrugations formed by radially inner corrugation valleys and radially outer peaks, adjacent peaks and valleys connected by generally radially extending tube wall sections;
- b. placing a braided wire shroud about the tube with the shroud extending along said radially outer corrugation peaks;
- c. moving a forming tool into engagement with the shroud and into a tube corrugation valley to yieldably deform a portion of said braided shroud;
- d. moving said deformed shroud portion substantially into the tube corrugation valley;
- e. conforming the shroud portion to the corrugation peaks adjacent said tube corrugation valley;
- and
- f. severing said shroud and tube at a desired location between said corrugation peaks.

- b. placing a braided wire shroud about the tube with the shroud extending along said radially outer corrugation peaks;
- c. moving a blunt tool into engagement with the shroud;
- d. urging said blunt tool radially inward with respect to said tube to deform a portion of said braided shroud into the tube corrugation valley to locate a valley of said corrugated tube;
- and
- e. severing said shroud and tube near a deformed area of said braided shroud in said valley.
