L'ensemble de raclage 1 comprend un porte-racle 2 auquel est fixée rigidement et amoviblement une racle 3 (ou deux racles 3a, 3b). Le porte-racle 2 comprend un corps 4 et un étau 5. Le corps 4, rigide, comporte une embase 6 destinée notamment à être fixée au châssis 7 d'une machine et des moyens-support 8.The scraper assembly 1 comprises a doctor blade holder 2 to which a doctor blade 3 is rigidly and removably attached (or two doctor blades 3a, 3b). The doctor blade holder 2 comprises a body 4 and a vice 5. The rigid body 4 comprises a base 6 intended in particular to be fixed to the chassis 7 of a machine and support means 8.

L'étau 5 comprend deux mâchoires 9a, 9b et des moyens de serrage 10. Deux branches 11a, 11b prolongent les mâchoires 9a, 9b et vont en s'écartant pour s'encliqueter sur les moyens-support 8 au moyen de reliefs d'accrochage complémentaires. L'ensemble de raclage 1 présente un axe principal 12 par rapport auquel sont profilés le porte-racle 2 et la racle 3 et deux plans de symétrie P (embase 6, moyens-support 8) et Q (étau 5, racle 3) susceptible de pivoter par rapport au plan P sur une course maximale de 90°.The vice 5 comprises two jaws 9a, 9b and clamping means 10. Two branches 11a, 11b extend the jaws 9a, 9b and move apart to snap onto the support means 8 by means of reliefs additional hanging. The scraper assembly 1 has a main axis 12 with respect to which the doctor blade 2 and the doctor blade 3 are profiled and two planes of symmetry P (base 6, support means 8) and Q (vice 5, doctor 3) to rotate relative to the plane P on a maximum stroke of 90 °.

Une première paire de reliefs d'accrochage 13a, 13b disposés en regard sont situés sur les branches 11a, 11b, à leurs parties extrêmes. Une seconde paire de reliefs d'accrochage 14a, 14b disposés en regard sont situés sur les moyens-support 8. Les reliefs 13a, 14a, 13b, 14b sont respectivement complémentaires pour coopérer de façon amovible.A first pair of attachment reliefs 13a, 13b arranged opposite are located on the branches 11a, 11b, at their end portions. A second pair of attachment reliefs 14a, 14b arranged opposite are located on the support means 8. The reliefs 13a, 14a, 13b, 14b are respectively complementary for cooperating in a removable manner.

L'une des deux paires de reliefs (en l'occurrence 14a, 14b) a une double pluralité de reliefs successifs semblables. L'écartement entre deux reliefs symétriques en regard varie de façon discrète d'une valeur maximale E1 à une valeur minimale E2.One of the two pairs of reliefs (in this case 14a, 14b) has a double plurality of successive similar reliefs. The spacing between two opposite symmetrical reliefs varies discreetly from a maximum value E1 to a minimum value E2.

Des moyens de serrage 15 structurellement confondus avec les moyens 10 permettent le blocage angulaire, autour de l'axe 12, de l'étau 5 par rapport à l'embase 6 entre deux positions extrêmes.Clamping means 15 structurally coincident with the means 10 allow the angular locking, around of the axis 12, of the vice 5 with respect to the base 6 between two extreme positions.

Il est prévu deux reliefs 13a, 13b en saillies tournées l'une vers l'autre et une double pluralité de reliefs en creux 14a, 14b successifs, à écartement variable, tournés dos à dos.There are two reliefs 13a, 13b projecting towards one another and a double plurality of hollow reliefs 14a, 14b successive, with variable spacing, turned back to back.

Il est prévu (figure 8) un étrier 16 formant à sa partie extrême l'embase 6. Le blocage sur le châssis 7 est réalisé par une tige filetée 19 traversant un trou taraudé de l'étrier à l'opposé de l'embase 6, terminée par un organe de manipulation 20 et par une plaque d'appui 21 venant sur un côté du châssis 7, dont l'autre côté vient coopérer avec une empreinte 22 de la face interne de l'embase 6 (ou une pluralité d'empreintes 22 pour différents châssis 7).There is provided (FIG. 8) a stirrup 16 forming at its end part the base 6. The blocking on the frame 7 is carried out by a threaded rod 19 passing through a threaded hole of the stirrup opposite the base 6 , terminated by a handling member 20 and by a support plate 21 coming from one side of the chassis 7, the other side of which cooperates with an imprint 22 on the internal face of the base 6 (or a plurality of footprints 22 for different chassis 7).

L'embase 6 peut être destinée à être manipulée en se présentant sous la forme d'une poignée (figure 7).The base 6 can be intended to be manipulated in the form of a handle (Figure 7).

Sur les figures 1 et 2, les deux mâchoires 9a, 9b sont de même longueur. Sur la figure 3, elles sont dissemblables, l'une 9a, ayant un prolongement 24. Une au moins des mâchoires 9a, 9b comprend, sur sa face interne 25, une butée 26 pour la racle 3 et à sa partie extrême, des reliefs 9c pour la tenue de la racle 3. Les deux faces 25 sont parallèles ou sensiblement.In Figures 1 and 2, the two jaws 9a, 9b are of the same length. In FIG. 3, they are dissimilar, one 9a, having an extension 24. At least one of the jaws 9a, 9b comprises, on its internal face 25, a stop 26 for the doctor blade 3 and, at its end, reliefs 9c for holding the doctor blade 3. The two faces 25 are parallel or substantially.

Le porte-racle 2 comporte (figures 4 et 5) au moins une plaque de renfort 27 profilée ayant une partie de fixation 28, une partie d'appui 29 et un décrochement 30 entre elles. Des moyens d'élasticité 31 assurent une élasticité du montage de la plaque 27 sur l'étau 5 et sont montés sur les moyens de serrage 10 traversant des lumières 32 de la plaque 27 et permettant le réglage. Le porte-racle 2 comporte (figure 6) sur un même corps 4, deux étaux 5a, 5b imbriqués et inclinés l'un par rapport à l'autre, les deux racles 3a et 3b (ou contre-racle) fonctionnant dans des sens opposés.The doctor blade holder 2 comprises (FIGS. 4 and 5) at least one profiled reinforcing plate 27 having a fixing part 28, a support part 29 and a recess 30 between them. Elastic means 31 ensure elasticity of the mounting of the plate 27 on the vice 5 and are mounted on the clamping means 10 passing through lights 32 of the plate 27 and allowing adjustment. The doctor blade holder 2 comprises (FIG. 6) on the same body 4, two clamps 5a, 5b nested and inclined relative to each other, the two doctor blades 3a and 3b (or counter doctor blade) operating in directions opposites.

Les moyens-support 8, rigidement fixés à l'embase 6, sont deux demi-cylindres en prolongation. Les reliefs 14a, 14b sont situés sur leurs faces externes. Les branches 11a, 11b ont chacune une forme générale de quart de cylindre et portent les reliefs 13a, 13b à leur extrémité libre sur la face interne. Elles ont une courbure et une dimension telles qu'elles enveloppent les moyens-support 8 de l'extérieur.The support means 8, rigidly fixed to the base 6, are two half-cylinders in extension. The reliefs 14a, 14b are located on their external faces. The branches 11a, 11b each have a general shape of quarter cylinder and carry the reliefs 13a, 13b at their free end on the internal face. They have a curvature and a dimension such that they envelop the support means 8 from the outside.

Un relief 14a, 14b est délimité par un fond concave correspondant à un peu plus d'un demi-cylindre et, de part et d'autre, une partie concave et une partie convexe s'écartant vers une ouverture. Un relief 13a, 13b a une forme de doigt recourbé terminé par une rotule en saillie vers l'intrados pouvant coopérer avec le fond concave du relief 14a, 14b.
