Apparatus for fabricating a strip-like reinforcement structure for a tire,
which includes a laying head for laying the strip. The laying head
includes a guidance passage for the strip formed by slots, rolling-down
rollers intended to cooperate with a form, a cutter for cutting the strip
into separate arches, and a turning-over mechanism for turning over the
strip about its own longitudinal axis for causing an opposite face of the
strip to face the form. The turning-over mechanism includes a frame
mounted on two bearings in a cradle of the laying head. The frame can
turn through at least 180.degree. with respect to the cradle for
inverting the strip.
