Furthermore, a resting part for a compression spring is connected to the shaft via a spreader ring so as to be fixed against rotation. This compression spring is supported at its other end on a bearing part which is integral with the one gripper part. A pivot movement of the closing lever results in a corresponding clockwise pivoting of the resting part. As a result, pivoting of the one gripper part into the clamping position is brought about via the compression spring. This one gripper part is blocked in its clamping position in which the compression spring is compressed and exerts a corresponding clamping force.

  • Patent number: 4896874
    Abstract: Continuously conveyed flexible flat structures, especially printed products, infed in an imbricated formation, are turned such as to retain their original imbricated product formation. This is accomplished by accelerating the flexible flat structures such that they are singled and then in such singled condition are deflected about a deflection axis directed transverse to the product infeed conveying direction. Thereafter the singled turned flat structures are decelerated and transported away in an opposite conveying direction. Between an infeed device and an outfeed device for the structures there is arranged a deflection mechanism comprising at least one endless revolving driven traction element guided between its two substantially linearly extending runs about a deflection wheel. This traction element has mutually spaced outwardly extending carrier or support elements, at the outer ends of which there are mounted controlled grippers for engaging a respective one of the flat structures.

  • Patent number: 4512457
    Abstract: A guided endless, revolvingly driven traction element is equipped with controlled gripper units or grippers arranged in spaced relationship from each other. These gripper units are adapted to grip one margin of the paper products which constitutes a lateral marginal edge of the product as seen in the transport direction thereof. The gripper units have substantially planar clamping faces inclined at the same direction with respect to the traction element for stiffening that portion of the transported paper products which laterally project from the gripper units. The transported printed products thus have imparted thereto a corrugation or undulation extending transversely with respect to the transport direction which results in the desired stiffening of the products.
