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: &#x2014;introducing the individual wires (&#x2033;&#x2033;) of the strand () into the stranding head () of a stranding machine () and &#x2014;partially or fully applying at least one coating agent to at least 50% of the individual wires (&#x2033;&#x2033;) of the strand () prior to the twisting of the individual wires (&#x2033;&#x2033;) to form a strand () or simultaneously with the twisting of the individual wires (&#x2033;&#x2033;) to form a strand () and &#x2014;twisting the individual wires (&#x2033;&#x2033;) to form a strand (), wherein at least 50% of the individual wires (&#x2033;&#x2033;) have been provided with at least one coating agent, and &#x2014;making a cable from at least one strand ().

A conveyor belt includes a first outer sheet disposed on a loadbearing side of the conveyor belt, a second outer sheet disposed on a drive side of the conveyor belt, and an embedded tension-member system disposed between the two sides, which is in the form of cords running parallel in the longitudinal direction of the conveyor belt. The tension-member system includes steel and, prior to vulcanization of the conveyor belt, an expandable coating which, after vulcanization of the conveyor belt, has a pore structure provided to at least portions of the tension-member system. The sheets are formed from a polymeric material with resilient properties. In some aspects, the volume of the coating after vulcanization is from 30 to 5000% higher than prior to vulcanization. The coating may contain at least one of a blowing agent and/or microbeads.
