ABSTRACT:
For removing cables from tubes, the invention provides a method wherein a cable is sucked from a tube, by connecting an evacuating pump to a cable lead-through apparatus one end of which is connected to the tube and the other end of which is provided with a lead-out opening for the free end of the cable. In one embodiment, the final portion of the cable is removed from the tube by connecting a compressor to the same cable lead-through apparatus. The invention also provides an apparatus for removing cables through suction force, wherein, in one embodiment, the same apparatus can also be used for installing cables in a tube through blowing.
