Abstract: A seal assembly includes a primary seal unit which seals off a first space from a second space, and a dam seal unit which delimits the second space from a discharge space so that a liquid introduced into the second space is dischargable into the discharge space. The primary seal unit includes a guide ring having a first lateral surface with a length, a rotating face which is guided on the guide ring, a retaining ring having a second lateral surface, and a secondary seal which acts between the guide ring and the retaining ring. The retaining ring is displaceable relative to the guide ring in a direction of the length of the first lateral surface. The second lateral surface of the retaining ring surrounds the first lateral surface of the guide ring at least over a part of the length of the first lateral surface.

Abstract: A method for a treatment of a product web which is transported in an advance direction includes guiding the product web through a treatment gap which is formed by a first treatment roll being arranged in a first working position and a contour tool, providing a second roll, moving the second roll into a second working position in which the second roll forms a second treatment gap with the counter tool, and moving the first treatment roll into a first parked position in which the first treatment roll does not form a treatment gap with the counter tool.

Abstract: A method for processing a roll includes providing a roll comprising an axis of rotation, providing at least one pulling device, and bending the roll in a direction opposite to a curvature of the roll via the at least one pulling device. The at least one pulling device is disposed at a radial distance from the axis of rotation of the roll.
