Abstract:
A sheet material processing apparatus comprising at least one treatment cell, a pair of rotatable path-defining rollers (28, 30) defining a sheet material path (20) through said cell, said path-defining rollers have a closed position in which said path-defining rollers are biased into contact with each other to form a nip (36) through which said sheet material path extends and an open position in which said path-defining rollers are spaced from each other, characterized in that said path-defining rollers (28, 30) are supported by bearings (70, 72) carried by eccentric sleeves (68) which are stationary in said closed position, and means (76) are provided for partly rotating said sleeves (68) thereby to withdraw said path-defining rollers (28, 30) from each other into said open position.
