<p>A system (10) for simultaneously introducing a cable (11) and another item (21) into a conduit (12) includes a pushing machine (13) and an air blower (15) which introduces the cable (11) into the conduit (12). The conduit (12) is split near the pushing machine (13) so that the item (21) may be attached to the cable (11) by means of an attachment device (25) carried by a bullet head (23) at the leading end of the cable (11). Alternatively, a projectible (35) may be attached to the leading end of the cable (11) and the item (21) may be attached at the junction of the cable (11) and projectile (35). A block (18) then connects the split ends (16, 17) of the conduit (12), and the cable (11) and other item (21) may then be moved together through the conduit (12) by the pushing machine (13) and air blower (15) which moves air against the projectile (35) to assist such movement.</p> |
