Method for making hose incorporating an embedded static ground conductor
First Claim
1. A method of manufacturing a hose structure incorporating an embedded static ground conductor comprising the steps of:
- extruding an elastomeric tube;
pressurizing the tube to effect a substantially rounded cross-section;
shortening a loosely braided wire bundle conductor in its axial direction such that the individual wires of the bundle are formed in a sinusoid transversely of the bundle axis;
compressing the shortened wire bundle in a direction transversely of its axis to flatten and form a ribbon type conductor;
laying the ribbon conductor onto the elastomeric tube parallel to and along the tube axis;
wrapping the tube with a textile material to hold the conductor in position on the tube;
extruding a cover of elastomeric material over the wrapped tube to form an integral hose structure; and
curing the hose structure.

Abstract
A method for the manufacture of a hose structure incorporating an embedded ground conductor comprising shortening a loosely braided bundle of fine conductor wire in the axial direction by compressing the bundle between two pairs of friction rollers rotating at different speeds. The wires are spread in a direction transversely of the bundle axis and flattened to form a ribbon type conductor that is laid on an uncured extruded tube, along the tube axis, and covered over with a textile wrapping and an elastomeric extrusion. Open steam curing of the structure results in a hose showing no appearance of an embedded conductor wire.
