Topic The band iron virtue which the virtue by the excessive drawing out and winding, with the inert revolution of the band iron coil fray is due to the springing out from the vessel Out, prevents the degradation of operating efficiency the vessel is offered Out.SolutionsIt possesses the mass which gives the load withstanding the spring back power of the band iron coil to the band iron coil in order to follow to the diameter change of the band iron coil, through the holding down roller supporter 2a who has the angular unrestricted fulcrum 4 like the hinge, with the rotary free holding down roller 2 which holds down the band iron drawing out immediately before part, it holds down the band iron from the band iron coil 5 upper part. In holding down roller supporter 2a forward the band iron entering side of the holding down roller 2, virtue it winds Out inside the vessel and board holding down section 3 in order to hold down the band iron which becomes loose, band iron virtue Out parallel to direction, it provides.
