Apparatus for making hose incorporating an embedded static ground conductor |
摘要 |
An apparatus 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.
