Claim 10:
11. A method for manufacturing a reinforcing ply comprising:
a strip preparation step (a) of preparing strips by repeatedly cutting a straight wire band at a preparation station, wherein the straight wire band comprises a plurality of reinforcing wires embedded in at least one layer of rubber and extending parallel to one another in the longitudinal direction of said straight wire band,
a butt-jointing step (c) of butt-joining the strips by their selvedges to form the reinforcing ply at a joining station,
said method comprising, between the strip preparation step (a) and the butt-jointing step (c), a turnover step (b) of turning over the strips at a turnover station, wherein the turnover step (b) comprises:
placing one of the strips, which is delimited in thickness by a first face and by a second face opposite said first face, on a first receiving surface in a first orientation, so that said strip rests and is held on said first receiving surface by its second face, and presents its first face as a visible face,
then turning over and transferring said strip from the first receiving surface to a second receiving surface with a reversing device associated with the second receiving surface, so that after transferring, the strip is in a second orientation where said strip is held against the second receiving surface by its first face, and presents its second face as the visible face, and
taking the strip from the second receiving surface and positioning the strip at the joining station using a gripping member, wherein the gripping member is configured to selectively transport strips from either the first receiving surface, or the second receiving surface, in order to form the reinforcing ply with one ply angle when using strips transported from the first receiving surface and form the reinforcing ply with another ply angle when using strips transported from the second receiving surface.
