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.
