The present invention relates to a method and to a device for processing highly flexural material in strip form. In order to provide a method and a corresponding device for processing highly flexural material 2 in strip form with optimization of working processes and increased production reliability, it is proposed that, in a method for processing highly flexural material 2 in strip form with a first and a second end region 10, 16, in particular of textile belt material 2, the two end regions 10, 16 of the highly flexural material 2 are essentially processed simultaneously, wherein one of the types of processing includes at least one sewing operation. In this case, ensured and consistent quality is achieved with a shortened working cycle time.
