Abstract
Abstract A woven fabric tape comprises a main portion and selvage portions provided along both sides of the main portion. The selvage portions are composed of a tissue which is more resistant against fraying than the tissue of the main portion. Each selvage portion of the fabric tape has a fused edge thereby to prevent fraying. A woven fabric suitable for the production of such fabric tapes comprises main portions and selvage forming portions, which are continuously and alternatively woven in a parallel relationship with each other. The selvage forming portions are composed of a tissue which is more resistant against fraying than the tissue of the main portions. The selvage forming portions are made of a thermally fusible material.
