The invention relates to a method for filling in a tension member in particular for conveyor belts, in particular a tension member which is configured as a steel cable. The method is intended to allow the full penetration of the tension member structure. Here, the method contains at least the following method steps: —introducing the individual wires (2, 2′, 2″, 2′″, 2″″) of the strand (5) into the stranding head (1) of a stranding machine (10) and—partially or fully applying at least one coating agent to at least 50% of the individual wires (2, 2′, 2″, 2′″, 2″″) of the strand (5) prior to the twisting of the individual wires (2, 2′, 2″, 2′″, 2″″) to form a strand (5) or simultaneously with the twisting of the individual wires (2, 2′, 2″, 2′″, 2″″) to form a strand (5) and—twisting the individual wires (2, 2′, 2″, 2′″, 2″″) to form a strand (5), wherein at least 50% of the individual wires (2, 2′, 2″, 2′″, 2″″) have been provided with at least one coating agent, and—making a cable from at least one strand (5).
