Since the outer diameter is 350 mm, even if you lower the lower end of the arm and use it halfway to load a base paper roll whose outer diameter is less than 350 mm, the rotary braking device will come into contact with the base paper roll shooter, making it impossible to load this small diameter roll that weighs 50 kg. There was an inconvenience in that a worker had to lift the base paper roll and fit both ends of the paper tube into the core chuck.
