Abstract
An oil recovery apparatus for a roll apparatus by which oil inside a roll mantle can be recovered efficiently even when the roll mantle rotates at a high speed. The roll apparatus includes shoe (5) having a contact portion (7) positioned at an upper portion inside a roll mantle (4), and an oil recovery pan (8) for recovering oil (50) entrained inside the roll mantle (4) upon rotation of the roll mantle (4). The oil recovery pan is disposed below the contact portion (7) on an upstream side in the direction of rotation of the roll mantle (4) with respect to the contact portion (7). Further, an outer edge upper end portion (12) of the oil recovery pan (8) extends to a position proximate to the inner circumferential face of the roll mantle (4) within a range in which the outer edge upper end portion (12) does not interfere with an oil film formed from the oil (50) entrained inside the roll mantle (4).
