御装置。 In a mechanism in which the end of a rolled film supported on a shaft is guided to a bag making machine via a plurality of guide roll groups, and the film is pulled behind the bag making machine, the shaft and a torque motor 27 are connected to each other. concatenate,
While the shaft is driven by the torque motor, a tension roll 36 is freely displaceably installed between the group of guide rolls, and the tension roll 36 is moved against the surface of the film by the load of a spring 37. At the same time, the end of the magnetic core rod 41 in the differential transformer 40 is provided opposite to the tension roll 36, and the torque motor 27 is connected to a power source via the differential transformer 40. This is a film feed amount control device for a packaging machine.
