Coupling for the tending-side end of a roll in a paper machine or paper

Abstract

A coupling arrangement for the tending-side end of a roll in a paper machine, such as a suction roll or a variable-crown roll, or a roll in a paper finishing machine, such as a variablecrown roll or a heated roll in a calender for paper. Through this coupling arrangement, energy media are passed into the roll, such as pressure fluid and/or compressed air, lubricating media, such as lubrication oil and/or water, and cleaning media, such as hot water. The coupling arrangement includes an openable shield casing which is tightly connected with the tending-side end of the roll and a coupling flange or coupling flanges to which the various pipes and/or hoses are attached. In the interior of the shield casing, there are connecting pipes and/or hoses which connect the pipe parts of the roll end with the hose and/or pipe parts departing from the coupling arrangement.
