Abstract
A cable (5) is inserted, by way of a free end (2.1), into a tube (2) wound around a tube reel (1) which is fixed, with its winding axis (y) vertical, onto a carrier (7). The carrier with the tube reel is subjected to a periodical movement having a vertical component and a longitudinal component. The vertical component is a vertical oscillation having a period (P) and an amplitude (A.sub.v =gP.sup.2 /32) for an, at any rate approximately, 'free-fall' movement during part of each period, preferably during half a period. The longitudinal component is an oscillating rotation around the vertical winding axis of the tube reel having the same period (P) and an amplitude (A.sub.L). The 'free-fall' movement is preferably commenced when the rotational direction of the oscillating rotation is reversed and becomes backward, as opposed to the insertion direction of the cable.
