Armoring tape for wrapping around a hose during its fabrication by a hose-wrapping machine. The tape is coiled into a roll having a hollow core from which the tape is unwound to be wrapped onto the hose. The hose-wrapping machine rotatably mounts the roll with the hose passing through the roll core, the roll axis being skewed to the hose axis by the helix angle at which the tape is to be wrapped onto and along the hose The hose is moved longitudinally through the longitudinally static roll and at the same time, the roll is rotated around the longitudinal axis of the non-rotating hose The armouring tape unwinds from the inside of the roll onto and along the hose so as to wrap the hose with a uniform helix of armouring tape The use of a tape containing an elastomer-embedded array of armouring cables enables armouring wires and elastomer layers to be applied without a stabilising layer of fabric, and greatly simplifies setting-up of machinery for hose fabrication. The use of a tape roll which can be unwound from its inside enables hoses to be wrapped without having to orbit rolls that are very large and heavy.
