1. An installation for manufacturing a reinforcing ply, said installation comprising:
a preparation station comprising a cutter configured to prepare strips by repeatedly cutting a straight wire band, 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 jointing station having a surface on which to form the reinforcing ply from the strips obtained from the preparation station,, said installation further comprising a turnover station for turning over the strips, which is interposed between the preparation station and the jointing station, the turnover station comprising:
a first receiving surface, arranged to receive one of the strips prepared by the preparation station and to hold said strip prepared by the preparation station in a first orientation in which said strip, which is delimited in thickness by a first face and by a second face opposite said first face, rests and is held on said first receiving surface by its second face, and presents its first face as a visible face,
a second receiving surface associated with a reversing device, wherein said reversing device is configured to transfer the strip initially placed and held on the first receiving surface, from said first receiving surface to said second receiving surface, thus turning over the strip so as to confer on said strip a second orientation that is the reverse of the first orientation, wherein in the second orientation said strip is held against the second receiving surface by its first face, and presents its second face as the visible face, and
a gripping member configured to take the strips individually and selectively from the first receiving surface or from the second receiving surface in order to selectively construct the reinforcing ply by successively butt-jointing the strips by their selvedges on the surface of the jointing station, wherein the reinforcing ply has one ply angle when formed from strips taken from the first receiving surface and the reinforcing ply has another ply angle when formed from strips taken from the second receiving surface.
