A positioning device has two transport arms for alternately transferring plate-shaped objects from a storage position into an operational position. The transport arms are each displaceable by means of a separate manipulator, so that a quick exchange of the objects is possible. The manipulators each comprise two parallel Y-guides which are fastened to a frame, and an X-guide which is displaceable along the two Y-guides, while the transport arms are each displaceable along one of the X-guides. The positioning device is used in an optical lithographic device for alternately placing masks on a mask support. A machine frame of the optical lithographic device to which the mask support is fastened is coupled to the frame of the positioning device by spring members. To render an accurate positioning of the masks on the mask support possible, the optical lithographic device is provided with an optical sensor system which is coupled to an electronic control unit for controlling the positioning device.

A method of manufacturing an elongate article, in particular an optical cable which comprises a carrier member having channels or bores and is provided with elongate elements, for example, optical fibres, the elongate element being inserted into the end of a channel or bore and the carrier member being subjected to a periodic movement, the elements moving in the channel or bore under the influence of the movement and as a result of their mass inertia. The invention also relates to a device for carrying out the method and to elongate articles, for example, optical cables manufactured by means of the method.
