Abstract
The roll comprises a stationary support construction (11) and a roll mantle (12) revolving around the construction, which mantle is supported from its inner face (12′) on the support construction (11) by at least one hydraulically loaded loading member (13), by which the roll mantle (12) is loaded against a backup roll (20) which forms a nip (N) with the roll. The oil removing arrangement comprises an oil collecting equipment (90) fitted in the space between the outer face (11″) of the support construction (11) and the inner face (12′) of the roll mantle (12), in which oil collecting equipment there is an oil guide plate (91) which is supported at least on the support construction (11), which is arc-shaped in the direction of the circumference and which forms a first oil guide face. At the lateral edges of the oil guide plate (91), there are radial side walls (93,94) directed towards the support construction, and at the curved rear edge there is a curved rear wall (92). In the space between the oil collecting equipment (90) and the outer face (11″) of the support construction (11), a flow passage is formed, along which the oil present in the roll is guided i…
