    • 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.
    • 用于检测待测试的未硫化轮胎坯料或硫化气动车辆轮胎中的至少一个的侧壁区域中的套管层中的加强构件的布置中的缺陷的装置和方法。 加强构件可以包括可磁化材料,并且该装置可以包括支撑装置,其可旋转地支撑围绕旋转轴线旋转的未硫化轮胎坯料或硫化气动车辆轮胎中的至少一个,以及测量磁场强度的至少一个传感器 在由通过异质磁场移动的加强构件的布置中的缺陷产生的感应产生的异质磁场中。 至少一个传感器可以位于侧壁的径向区域中的径向测量位置。 该装置还可以包括控制未硫化轮胎坯料或硫化气动车辆轮胎的旋转的旋转控制器和耦合到至少一个传感器以便接收检测到的磁场强度的评估装置。
