Abstract: An auto-threading apparatus is disclosed. In a film processing line incorporating a transferring/receiving mechanism having a take-up unit, two pairs of cutters are moved by twos in crosswise directions of a film to cut away side narrow portions of the film by one pair of cutters. Chain clips catch the film ends to longitudinally divide the film into three parts by the other pair of cutters. The side portions of the 3-divided film are cut away by rotary cutters. The left central portion thereof is cut away by moving the other pair of cutters toward the center. The film is transferred to and received by the chain clips.

Abstract: In a film processing line incorporating a transferring/receiving mechanism having a take-up unit, two pairs of cutters are movable in crosswise directions of a film, and narrow portions of the film at sides thereof are cut away by one pair of cutters. Chain clips catch the sides of the film and the other pair of cutters longitudinally divide the film into three parts. The side parts of the divided film are cut away by rotary cutters. The central part thereof is cut away by moving the other pair of cutters toward the center of the film. A portion of the film is thus transferred to and received by the chain clips.
