    • A gripping means consisting of two jaws (2, 3) pivotable in relation to each other on a shaft (32), said shaft (32) being secured to one jaw (3) and extending through a sleeve (53) secured to the other jaw (2), the shaft (32) having an enlarged section (39) adjacent to and having substantially the same outer diameter as the sleeve (53). A tightly coiled helical spring (70) surrounds both the sleeve (53) and the section (39). One end portion of the spring (70) is freely movable on the enlarged section (39) and can be rotated at least in one direction in relation thereto. The other end of the spring (71) is connected to a roller (4) which is pivotably journalled and can be turned upon peripheral contact with a tread surface (9A, 9B) arranged at a desired position along the path of the gripping means so that the gripping means opens at a position exactly defined by the tread surface (9A, 9B).
    • 一种由在轴(32)上可彼此相对枢转的两个夹爪(2,3)组成的夹持装置,所述轴(32)固定到一个夹爪(3)上并延伸穿过固定到另一个的套筒(53) 所述轴(2)具有与所述套筒(53)相邻并具有与所述套筒(53)基本相同外径的扩大部分(39)。 紧密卷绕的螺旋弹簧(70)围绕套筒(53)和部分(39)。 弹簧(70)的一个端部可以在扩大部分(39)上自由移动,并且可以至少相对于一个方向旋转。 弹簧(71)的另一端连接到可枢转地支承的辊(4),并且可以沿着沿着夹持装置的路径布置在期望位置的胎面表面(9A,9B)周边接触而转动, 夹紧装置在由胎面表面(9A,9B)精确限定的位置处打开。

    • Méthode pour l'insertion de suppléments dans des journaux ou des revues (20) ainsi qu'une méthode générale pour ouvrir des journaux ou des revues avant le processus d'insertion, comprenant le transport de journaux séparés à l'état ouvert à travers un poste d'insertion. Les dos des journaux sont maintenus en contact ferme avec des pinces ressemblant à des poches (14, 45), disposées sur un transporteur. Lesdites pinces (14, 15) s'ouvrent temporairement lorsqu'elles passent le poste d'insertion (60, 61), le contact ferme entre le journal (20) et les pinces étant toujours maintenu. Un appareil permettant la mise en oeuvre de ladite méthode comprend un transporteur (10) et un dispositif d'insertion (60, 61) doté de moyens (14, 21, 22, 23, 25, 26) pour ouvrir chaque journal (20) ainsi que des moyens (60, 61) permettant d'insérer un supplément dans le journal ouvert. Ledit appareil peut également comprendre un deuxième transporteur (40) doté de pinces séparées (45) pour chaque journal, ledit deuxième transporteur (40) s'étendant à travers le premier transporteur (10). L'appareil comprend également des moyens (P11, P12, P13) pour ouvrir temporairement chaque pince lors de son passage à travers le poste d'insertion disposé dans (60, 61; P12) le matériel d'insertion. De plus, l'appareil comprend des moyens (46) permettant de maintenir l'orientation et la position du journal par rapport à la pince (45) lorsque celle-ci est ouverte dans le poste d'insertion (P12).

    • In a method and apparatus for withdrawing a selected number of consecutive copies of newspapers (2), for instance, from a series of said products travelling horizontally and arranged in overlapping formation (4), a gripping means in the form of a mechanical clamp (10) is caused to engage with the desired number of copies by the front edge of the clamp (10) being kept in contact with the formation along a selected distance (a), the clamp (10) being driven with a speed (V1) difference in relation to the formation (4, VO) such that a selected number of copies enter the clamp (10) along the selected distance (a). At the end of the distance the clamp (10) is closed and its speed thereafter accelerated in relation to the formation, to a speed (V2) considerably higher than that of the formation (4, VO), its direction deviating only marginally from the direction of movement of the formation. Only a few consecutive copies are withdrawn from the formation (4) so that no gaps occur in the formation (4).

    • Plant for stacking newspapers, which includes a collection station (9) and conveyor means (1, 2) for advancing a stream of mutually overlapping newspapers (8) towards the collection station (9), a finished stack (10) having a predetermined number of mutually, laterally displaced individual newspaper sheaves (11) each containing a predetermined number of newspapers. In accordance with the invention the conveying means comprises two separate conveyors (1, 2) in tandem, at least one of which is laterally turnable in relation to the other, between said conveyors (1, 2) there being a newspaper counter or sensor (5) connected to control electronics (7), which may be set for counting an optional number of newspapers and which, after the passage of a predetermined number of newspapers, is adapted for actuating means (4, 12) for laterally turning the approach conveyor (1) and the stream of newspapers conveyed by it a predetermined angle.
