Metal coil compression binding apparatus

A metal coil compression device configured to axially compress a metal coil placed with an axis thereof vertical to bind the metal coil with a binding band, the metal coil compression device comprising:

• a lifting device configured to generate a vertically downward pressing force;
• a cylindrical outer pressure barrel that is supported by the lifting device so that it can move vertically and has an opening opened vertically downward on a bottom thereof;
• a cylindrical inner pressure barrel that is located inside a peripheral wall of the outer pressure barrel;
• and
• a connecting mechanism that is located between the inner pressure barrel and the outer pressure barrel, and connects the inner and outer pressure barrels so that the inner and outer pressure barrels are vertically engaged and are supported relatively rotatably in a circumferential direction, wherein
• the outer pressure barrel has an outer recess in the peripheral wall of the outer pressure barrel, the outer recess being recessed vertically upward from a bottom end, and
• the inner pressure barrel has
• an inner recess in a peripheral wall of the inner pressure barrel, the inner recess being recessed vertically upward from a bottom end, and
• a coil pressing surface that is located at the bottom end of the peripheral wall of the inner pressure barrel and makes contact with a top of the metal coil to transmit the vertically downward pressing force to the metal coil.
