  • Patent number: 5152235
    Abstract: A sewing apparatus for forming cuffs for sweat jackets or anklets for sweat pants or the like. The apparatus includes a movable table carrying an end of an elastic tape continuous to a supply source. The tape advances on a carrying table to a cutting device where the tape is cut. The front end of the tape is transferred to gripping blades which can be inverted, simultaneously with the return movement of the movable table. The tape is further let out toward the gripping blades by a predetermined length feeding device and the gripping blades turn so that the tape front end is folded back on the tape rear part. The tape rear part is cut off and the folded cut-piece is supplied to a sewing machine by a conveying device automatically and sewn to join both ends along the cut line.
