Arrangement for removing oil in a roll

An arrangement for removing oil in an roll, comprising:

• a roll having a stationary support construction with an outer face and a roll mantle revolving around said construction, wherein the mantle has a inner face, and the mantle is supported from the inner face on the support construction by at least one hydraulically loaded loading member which loads or shifts and loads the roll mantle against a backup roll that forms a nip with the roll;
• and
• at least one oil collecting equipment positioned in a space between the outer face of the support construction and the inner face of the roll mantle, and which is supported against the support construction, the at least one oil collecting equipment having an outer wall curved in the direction of the circumference and fitted between the outer wall and the support construction, which outer wall and inner wall extended across an axial direction, the outer and inner wall having lateral edges which are interconnected by radial side walls, and rear edges which are attached to an axial oil guide duct, in which there are openings opening into the interior of the oil collecting equipment, such that oil gathered on the inner face of the roll mantle is guided through an inlet opening formed by the outer and inner face walls of the oil collecting equipment into the oil collecting equipment and from a rear part of the oil collecting equipment further into an axial oil guide duct and from it further through radial oil guide ducts, into a central portion of the roll, from which the oil is passed out through an axial oil dram duct.

A roll with oil removing apparatus comprising:

• a stationary support construction having an outer face;
• a roll mounted to revolve about the stationary support construction, the mantle having an inner face which is engaged and supported by at least one hydraulically loaded loading member which extends from the stationary support construction to load the roll mantle against a backup roll forming a nip with the roll mantle;
• at least one oil collecting equipment positioned in a space defined between the outer face of the support construction and the inner face of the roll mantle, the at least one oil collecting equipment being supported by the support construction, the at least one oil collecting equipment comprising at least a first guide plate that comprises at least a curved portion in the direction of the circumference of the roll mantle and spaced from the inner face of the roll mantle, wherein a flow passage is defined between the first oil guide plate and the outer face of the support construction;
• and
• oil guide passages passing out of the roll which communicate with the flow passage, such that oil that collides against the at least one loading member is passed into the oil guide arrangements for passage out the roll.
