Abstract

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).

First claim

The invention claimed is:

1. 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 includes a rubber material;
twisting the individual wires to form a strand; and
making a cable comprising the 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; and,
wherein the tension member comprises the cable.

2. The method as claimed in claim 1 , wherein the at least one coating agent is applied partially or completely upon at least 80% of the individual wires before the twisting the individual wires to form a strand.

3. The method as claimed in claim 1 , wherein the at least one coating agent is applied completely upon at least 50% of the individual wires before the twisting the individual wires to form a strand.

4. The method as claimed in claim 1 , wherein the application of the coating agent is performed by way of an injector, a spray device, or combination thereof.

5. The method as claimed in claim 1 , wherein the coating agent further comprises expandable microspheres.

6. The method as claimed in claim 1 , wherein the strand forms a core strand of the cable.

7. The method as claimed in claim 1 , wherein the cable is a steel cable.

8. The method as claimed in claim 1 , wherein the cable is a steel-hybrid cable.

9. 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; and
making a cable comprising the 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; and,
wherein the tension member comprises the cable.

10. The method as claimed in claim 9 , 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.

11. The method as claimed in claim 9 , wherein the at least one coating agent is completely applied upon at least 50% of the individual wires before the twisting the individual wires to form a strand.

12. The method as claimed in claim 9 , wherein the application of the coating agent is performed by way of an injector, a spray device, or combination thereof.

13. The method as claimed in claim 9 , wherein the strand forms a core strand of the cable.

14. The method as claimed in claim 9 , wherein the cable is a steel cable.

15. The method as claimed in claim 9 , wherein the cable is a steel-hybrid cable.

16. The method of claim 1 , wherein the applying the at least one coating agent occurs during the twisting of the individual wires to form the strand.

17. The method of claim 1 , further comprising selecting an amount of the at least one coating agent to apply to mitigate a number of cavities prior to applying the at least one coating agent and to provide complete rubberization of a belt containing cable.

18. The method of claim 1 , further comprising selecting the at least one coating agent based on a tension member material and a tension member construction.

19. The method of claim 1 , wherein applying the at least one coating agent comprises brushing the at least one coating agent on to the individual wires.
