Description

Technical Field

[0001] The utility model relates to the technical field of rubber strips, in particular to a rubber strip for a circular loom. Background Art

[0002] When the circular loom is working, the shuttle body will move rapidly along the annular guide rail. The shuttle body realizes rolling cooperation by means of the shuttle wheels installed on both ends of the shuttle body and the grooves on the annular guide rail. When the shuttle body rotates rapidly, the centrifugal force will increase the load on the guide wheel and the guide rail. When the force exceeds the load, the frictional heat and internal heat may cause deformation or even fracture, so that its service life cannot reach the expected value. At the same time, it is not easy to repair after damage and usually needs to be replaced. In addition, the cost of the guide wheel and the guide rail is relatively high, which makes the maintenance cost high. Utility Model Content
