Abstract
Abstract A flexible hose having a conductor element extending along the hose wall. The conductor element is in the form of an elastic conductive strip or tape having a generally flat configuration and formed of elastic yarns or threads extending along the strip or tape and flexible metal wires or threads of metal braided, plaited or interwoven with the elastic yarns or threads. The conductive element being of this form is of use especially for extruded hoses, since it can be laid along the hose parallel to the hose axis and will stretch to accommodate hose elongation.
