Disclosed is a seal strip, comprising a tubular seal strip body with a first end (116) and a second end (117), wherein the first end (116) extends into the second end (117) and is securely connected to the second end (117) by a sewing thread (113). Further disclosed are a method and a device for sewing the seal strip, wherein the sewing device comprises a seal strip feeding machine (1), a device (2) for positioning the ends of the seal strip, a device for inwardly folding an edge of the seal strip, a device (3) for butt-joining the ends of the seal strip, a device (5) for threading a needle for the seal strip, and a device (4) for sewing the seal strip. The two ends of the seal strip are securely connected by the sewing thread, providing a high connection strength; and the method and device for sewing the seal strip can accomplish complete automation in sewing the seal strip, thus greatly improving efficiency during the production and processing of the seal strip.
