    • Device for aligning automatically the contours of two plies to be sewed one upon the other, consisting of three superimposed blades (1, 2, 3) hinged to one another at one end by means of a cross pin (4) so as to generally form a double pliers. From the pin (4) onwards the device comprises: elastic means (7) which can be calibrated and tending to press the blade (2) against the blade (1) and the blade (3) against the blade (2); means (8) to vary the angular opening between the blades (1, 2, 3), means (9) to adjust the maximum and minimum angular opening between the blades (1, 2, 3), abutting means (28a, 28b, 28c) to define the alignement position of the contours of the plies (T, t) to be sewed and means to bring the plies to the alignment on an air pad or by friction.
    • 用于自动对准要彼此缝合的两层的轮廓的装置,其由三个叠置的叶片(1,2,3)组成,所述三个叠加的叶片(1,2,3)在一端通过十字销(4)彼此铰接,以便大致形成 一个双钳子。 从销(4)起,装置包括:弹性装置(7),其可以被校准并倾向于将叶片(2)压靠在叶片(1)上,并且叶片(3)抵靠叶片(2); 用于改变所述叶片(1,2,3)之间的角度开口的装置(8),用于调节所述叶片(1,2,3)之间的最大和最小角度开口的装置(9),邻接装置(28a,28b, 28c)以限定要缝制的层片(T,t)的轮廓的对准位置,以及使层片在气垫上或通过摩擦使其对准的装置。
