Title
(EN) EQUIPMENT AND METHOD FOR REPLACING A BAND-LIKE DOCTOR BLADE
(FR) EQUIPEMENT ET PROCEDE POUR REMPLACER UNE LAME DE RACLOIR DE TYPE BANDE
Abstract
(EN)
The invention concerns an equipment for replacing a doctor blade, a doctor blade, and a method in the use of band-like doctor blade. The equipment for replacing a doctor blade comprises a doctor blade (11) placed in a reel, which doctor blade can be fed into the blade holder (14) for the doctor blade. The blade holder (14) for the doctor blade (11) comprises locking devices in its connection for locking the doctor blade (11) in the blade holder. The equipment comprises a doctor blade (11) which comprises notches (18a1, 18a2...) at the edge, the doctor blade being fed over a length equal to the distance (E1) between the notches at the edge, while the notches (18a1, 18a2) at the edge are placed, during operation of the doctor blade (11), at both ends of the blade holder (14) and permit bending of the band-like doctor blade (11) in the way of a normal blade in an operating situation.
(FR)
L'invention concerne un équipement permettant de remplacer une lame de racloir, une lame de racloir et un procédé d'utilisation d'une lame de racloir de type bande. Cet équipement qui permet de remplacer un lame de racloir comporte une lame de racloir (11) placée dans un rouleau, laquelle lame de racloir peut être amenée dans le porte-lames (14) destiné à la lame de racloir. Ce porte-lames (14) destiné à la lame de racloir (11) est pourvu de dispositifs de blocage permettant de bloquer la lame de racloir (11) dans le porte-lames. Cet équipement comporte une lame de racloir (11) comprenant des encoches (18a1, 18a2...) sur son bord, ladite lame de racloir étant amenée à avancer sur une distance égale à la distance (E1) entre les encoches du bord. Ces encoches (18a1, 18a2...) du bord sont placées, lors du fonctionnement de la lame de racloir (11), sur les deux extrémités du porte-lames (14) et permettent la flexion de la lame de racloir (11) de type bande à la manière d'une lame normale dans une situation d'utilisation.
