The invention concerns, in particular, a device (1) for preparing a reinforcing strip intended for producing a tyre, said device making it possible to prepare an undulated reinforcing strip (21) from a flat reinforcement strip (20), said device comprising: a continuous conveyor (4) suitable for guiding a plurality of fingers (5) along a closed circuit comprising at least one straight path portion, said fingers being suitable for bearing against a first face of the strip, a rotary plate (6) that rotates about a plate axis (AP), said rotary plate carrying a plurality of rotary rollers (7) of axes parallel to the plate axis, said rollers being distributed in a circle (61) substantially concentric to the plate axis, said rollers being suitable for bearing against a second face of the strip, guide means (9, 10) for guiding the flat reinforcement strip entering the device, synchronisation means for synchronising the rotation of the rotary plate and the advancement of the continuous conveyor, in which the closed circuit comprises an interference portion (PI) in which the synchronisation means allow the fingers and the rollers to move in rotational movements in a common plane perpendicular to the plate axis, the fingers and the rollers being interposed in said interference portion in such a way as to produce undulations in the strip extending in said common plane. |
