element 1 is firmly clamped in the holding means 2 in a known way the doctor blade element 1 is pressed with a front doctor blade edge 5 against a fibrous web 7 running over a roller 6 to exchange the doctor blade element 1 the latter must be drawn out of the holding means 2 laterally or axially with respect to the roller c in the direction of the arrow a for this purpose then the doctor blade element 1 is provided with a lateral prolongation which is designed as a grip part 8 the grip part 8 possesses a width b which corresponds at least approximately to the width of the holding means 2 a region a of the doctor blade element 1 the functioning of said region being unchanged consequently remains on the front side as may be seen particularly from the enlarged illustration in fig2 the grip part 8 narrows outwardly toward its end to a width d an oblique front edge 9 of the grip part 8 is thereby obtained the rear edge 10 of the grip part 8 constitutes a prolongation of the rear edge 11 of the doctor blade element 1 as is clear there is a radius.
