Method for producing a tension member, tension member, and use thereof
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 ).
1. A method for producing a tension member, the method comprising:
applying a coating agent at least partially to at least 50 percent of a plurality of wires that have been guided into a stranding machine, wherein the coating agent includes a rubber material and expanded microspheres; and
subsequent to applying the coating agent, twisting the individual wires to form a strand of the tension member.
2. The method of claim 1 , further comprising making the tension member from the strand and one or more additional strands.
3. The method of claim 1 , further comprising applying the coating agent upon at least 80 percent of the plurality of wires.
4. The method of claim 1 , wherein applying the coating agent comprises applying the coating agent completely to at least 50 percent of the plurality of wires.
5. The method of claim 1 , wherein each of the plurality of wires is an individual wire.
6. The method of claim 1 , further comprising an injector configured to apply the coating agent.
7. The method of claim 1 , wherein the formed strand is a core strand of the tension member.
8. The method of claim 1 , wherein the tension member is a steel cable.
9. The method of claim 1 , wherein the tension member is a steel-hybrid cable.
10. A method for producing a tension member, the method comprising:
introducing individual wires into a stranding head of a stranding machine;
guiding the individual wires into the stranding machine;
subsequent to guiding the individual wires into the stranding machine, applying at least one coating agent at least partially to at least 50% of the individual wires, wherein the at least one coating agent is a rubber material;
twisting the individual wires to form a strand;
wherein the at least one coating agent is applied prior to twisting the individual wires to form the strand;
wherein the coating agent comprises expanded microspheres.
11. The method as claimed in claim 10 , wherein the at least one coating agent is partially or completely applied upon at least 80% of the individual wires before the twisting the individual wires to form a strand.
12. The method of claim 10 , further comprising applying additional coating agent during the twisting of the individual wires to form the strand.
13. The method of claim 10 , further comprising selecting the at least one coating agent based on a tension member material and a tension member construction.
14. The method of claim 10 , wherein applying the at least one coating agent comprises brushing the at least one coating agent on to the individual wires.
15. The method of claim 10 , forming a cable having a construction of 7×7, where the strand is comprised of 7 wires.
16. The method of claim 10 , forming a cable having a construction of 7×19, the strand comprised of 19 wires.
17. The method of claim 10 , forming a cable using the strand as a core strand.
18. The method of claim 10 , the individual wires comprising steel.
19. The method of claim 10 , applying the at least one coating agent to the formed strand after the twisting the wires to form the strand.
20. The method of claim 10 , forming a conveyor belt with the strand.
21. The method of claim 10 , the microspheres are hollow balls comprised of one or more of glass, phenolic resin, carbon and/or a thermoplastic material.
