Summary:PURPOSE:To prevent a faulty disagreement in positioning of a design in packing by providing a timer to a control part which controls the operation of a pusher according to signals from a sensor at an end position of a design-bearing film. CONSTITUTION:A time is provided to a control part 17 which controls the operation of a pusher 9 according to signals from a sensor 10. If, for some reason, a detection mark 62 on a film 6 passes the sensor 10 without stopping, the control part 17 puts this occurrence in storage; in this instance, by suspending the operation of the pusher 9 for a specified time, for example, in the range from a few seconds to several minutes, the film 6 is fed somewhat in excess of containers 4. Therefore the positioning of the design 61 on the film 6 is automatically corrected properly. This method thus prevents defective packing.
