    • Device and method to control the straightness and torsions of a long product (11), comprising at least two profile-detection devices (12a, 12b, 12c), each presenting a visual field (13) that includes a perimeter segment (18a, 18b, 18c) of the section of the product (11). The detection devices are aligned along the product (11) and are oriented so as to detect homologous perimeter segments (18a, 18b, 18c) located on different planes. The device also comprises a command unit which receives and compares with each other the section images detected at the same instant by the detection devices (12a, 12b, 12c) and determines, according to this comparison, the lack of straightness and/or the presence of torsions in the product (11).
    • 用于控制长产品(11)的平直度和扭转的装置和方法,包括至少两个轮廓检测装置(12a,12b,12c),每个轮廓检测装置(12a,12b,12c)具有包括周边部分(18a,18b) ,18c)的产品(11)的部分。 检测装置沿着产品(11)对准并且被定向成检测位于不同平面上的同源周边段(18a,18b,18c)。 该装置还包括命令单元,其接收并相互比较由检测装置(12a,12b,12c)在同一时刻检测到的截面图像,并根据该比较确定缺乏直线度和/或存在 的产品(11)中的扭转。
