ABSTRACT OF THE DISCLOSURE An apparatus for crimping a textile fibrous material, includes a pair of nip rolls, a stuffing box disposed adjacent to and downstream of the nip rolls, and a channel disposed in a doctor blade of the stuffing box for the passage therethrough of a pressurized fluid and having an outlet opening to an end surface of the doctor blade through which the pressurized fluid is sent into a clearance between the peripheral surface of each roll and the end surface. The apparatus includes a seal block or plug received loosely in a recess defined in the end surface between the outlet and an outer end of the clearance. The plug is urged mechanically or fluidically against the peripheral surface of the roll to prevent leakage of the pressurized fluid from a stuffing box in the stuffing box through the clearance to the outside air.
