Abstract: A high-temperature lubricating oil composition is provided, which is resistant to hardening and sludge formation, and displays minimal evaporation loss and superior thermal stability, even under practical high-temperature open system conditions such as those found in a tenter. A lubricating oil composition that provides excellent lubrication without damaging members used within working machinery is also provided. The lubricating oil composition comprises a polyolester based synthetic oil and a C12 to C72 fatty acid and/or a diphenylamine derivative containing an arylalkyl group with a number average molecular weight of 400 to 800.

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.

Abstract: This invention provides a drawing machine for pinching and stretching a film-like material of the type having rails installed extending from an inlet section to the outlet section and returning in the opposite direction from the outlet section back to the inlet section of the drawing machine. There is a clip propelling unit moving on the rails for pinching and stretching the film-like material, and elements for generating mutually repelling magnetic fields between the rails and clips, whereby the clips are movable in the non-contact state while floating from the rail guide surfaces. Thus, no foreign substances are generated, cleanliness of products is enhanced, no noise is generated, the work environment is improved, energy is saved, and highspeed operation is attained.
