ABSTRACT:
Device and process for detecting defects in an arrangement of reinforcing members in casing plies in a sidewall region of at least one of an unvulcanized tire blank or a vulcanized pneumatic vehicle tire to be tested. The reinforcing members may include a magnetizable material and the device may include a support device that rotatably supports the at least one of the unvulcanized tire blank or the vulcanized pneumatic vehicle tire in rotation around a rotational axis and at least one sensor that measures magnetic field intensities in a heterogeneous magnetic field resulting from inductions generated by the defects in the arrangement of the reinforcing members moving through the heterogeneous magnetic field. The at least one sensor may be positioned in a radial measuring position in a radial region of the sidewall. The device may also include a rotation controller that controls the rotation of the unvulcanized tire blank or the vulcanized pneumatic vehicle tire and an evaluation device coupled to the at least one sensor to receive the detected magnetic field intensities.
