Claim:
A seal adapted to seal an end of a fluid chamber which supplies fluid to a roll, comprising: at least one supporting side wall, an upper wall on said at least one supporting side wall, said upper wall including an upper concave surface adapted to engage an outer surface of the roll, said upper wall including at least one opening, opposite end walls connected to ends of said at least one supporting side wall, a lubricant chamber defined between and surrounded by said at least one supporting side wall, said upper wall and said end walls, for holding a lubricant therein, with said upper wall in covering relation to said lubricant chamber, said lubricant chamber being in fluid communication with said opening, said seal being made of a deformable and resilient material, and said seal having a configuration that provides that the seal deforms as a result of external force on said seal when in contact with the roll to increase pressure in the lubricant chamber and cause said lubricant to be forced out of said lubricant chamber through said at least one opening to an interface between said seal and the roll.
