ABSTRACT OF THE DISCLOSURE A sealing apparatus is disclosed for sealing a movable blanket which extends through an extended nip defined by first and second cooperating press members. The apparatus seals the blanket relative to, and between, a first and second end of the first press member. The apparatus includes a first rotatable head which is disposed adjacent to the first end of the first press member. The first head is coaxial relative to the first press member and a second rotatable head is disposed adjacent to the second end of the first press member. The second head is coaxial relative to the first head and the first press member respectively. A first annular seal is disposed between the blanket and the first head for sealing the blanket relative to the first head. A second annular seal is disposed between the blanket and the second head for sealing the blanket relative to the second head such that when the first and second seals are in an inflated first and third position thereof, the blanket is permitted to rotate coaxially around the first press member. When the first and second seals are disposed in a deflated second position, the blanket is movable axially relative to the seals for replacing the blanket.
