    • A lubricator 2 supplies an unwound coil material as an alloy plate material 11 to a metal beverage can production line for forming the alloy plate material 11 into a metal beverage can. The lubricator 2 includes: a felt roll 21 configured to contain lubricating oil in a first outer circumferential section, a felt roll 22 with a second outer circumferential section, a plate material lift configured to switch between a first state in which the alloy plate material 11 contacts the first outer circumferential section of the felt roll 21 and the second outer circumferential section of the felt roll 22, and the first outer circumferential section and/or the second outer circumferential section apply the lubricating oil to the alloy plate material 11, and a second state in which the felt roll 21 and/or the felt roll 22 applying the lubricating oil in the first state are idly rotatable by separating from the alloy plate material 11, and an air receiving section configured to apply a driving force to the idly rotatable felt roll 21 and/or the idly rotatable felt roll 22 in the second state as switched by the plate material lift.
