The invention provides a method for repairing a rubber profile with a fabric on a hollow closed surface. The method comprises the following steps: preparing a repairing material, cleaning and
drying,
polishing and protecting, sewing, determining an external expansion area,
cutting a repairing strip, laminating, heating, pressurizing and the like. The method has the characteristics that the operation is simple, the product does not need to be completely disassembled, the damaged rubber profile can be quickly repaired, manpower and
material resources are remarkably saved in practical application, and the
assembly efficiency of a user is greatly improved; for a large profile which is dozens of meters and even hundreds of meters long, the technology can ensure excellent sealing performance on the basis of keeping the original structure of the profile. According to the airtight test
verification, the repaired product can meet the airtight requirement, the repaired part does not have the abnormal conditions such as falling or
cracking, the reliability is high, and the service life of the rubber profile is effectively prolonged.
