摘要： In a motion picture apparatus for perforated film including a film gate, a film claw, and means for moving the claw in-and-out and up-and-down relatively to the gate to intermittently engage the perforation of the film and to advance the film through the gate. Driving means are provided for the film and the latter forms a loose loop between the claw and the driving means. A motor is arranged to drive the driving means and the means for moving the claw. A loop restorer has an eccentric control surface, which is situated inside the loose loop formed by the film. A first toothed wheel showing a first tooth gap is connected to the eccentric control surface to drive it. The eccentric control surface is movable between a first position, in which the length of the film between the claw and the driving means has a maximum size and a second position, in which the length of the film between the claw and the driving means has a minimum size and the eccentric control surface having a rest position situated between the first position and the second position, in which rest position the control surface is out of engagement with the film in the film loop, so that a shortening film loop engaging the eccentric control surface will move it to the first position; a second constantly rotating toothed wheel, the second toothed wheel being driven by the motor in synchronism with the claw. The first tooth gap of the first toothed wheel is adjacent to the second toothed wheel, when the eccentric control surface is in the rest position. The second toothed wheel showing a second tooth gap of a range that corresponds to the part of the cycle of the claw movement, in which the claw is in engagement with the perforation of the film, whereas the second toothed wheel is toothed in a range corresponding to the part of the cycle of the claw movement, in which the claw is out of engagement with the perforation of the film.

摘要： A strip handling apparatus which comprises a drive, a device for receiving a supply reel having a coil of strip and a device for receiving a take-up reel for the strip. The device for receiving a take-up reel is coupled to the drive, whereas the device for receiving a supply reel is freewheeling and receives torque only by means of the strip. A detecting device is operatively connected with the device for receiving a supply reel and the device for receiving a take-up reel to find out the faster rotating one. The detecting device has a first and second position, in the first position of the detecting device the speed of the freewheeling device for receiving a supply reel is larger than the speed of the device for receiving a take-up reel, in the second position of the detecting device the speed of the device for receiving a take-up reel being larger than the speed of the freewheeling device. A torque reducing device is provided at least for the device for receiving a supply reel and having an operative and an inoperative position. The torque reducing device is controlled by the detecting device in the first position of the detecting device the torque reducing means being in the operative position, in the second position of the detecting means the torque reducing device being in the inoperative position.
