- the bearing body can for example ensure both the guiding in rotation of the roller and its immobilization in the transverse direction. It can also carry the means drive in rotation of the roller and / or means for precise adjustment of the position of the axis of the roller in order to control in particular the spacing of the two engraved rollers or their relative axial position.
- the object of the invention is to propose a new design for a machine for the mechanical treatment of paper which allows to carry out a faster change of engraved rollers, in particular for the purpose of limit the duration of this replacement, during which time the production of the machine is of course stopped.
- the invention provides a machine of the type described previously, characterized in that the bearing bodies of at least one of the engraved rollers are fixed in housings which are delimited at least in part by a removable flange which, when disassembled, releases a radial opening through which the bearing housing can be released from the housing in a radial direction, and in that the cradle which carries one of the engraved rollers pivots around a transverse axis parallel to the axes of rollers between a service position, in which the two rollers are tangents, and a clear position for dismantling the engraved rollers,
- FIG. 1 schematically illustrates part of a machine for the mechanical processing of paper, more particularly a part of the machine intended to ensure the embossing and the association of two strips of paper which pass between two engraved cylindrical rollers 10, 12, which are each mounted for rotation about an axis, respectively A1, A2, between vertical uprights 14, 16 which are arranged in planes perpendicular to the axes A1, A2, at the two axial ends of the rollers 10, 12.
- the two axes A1, A2 are arranged in the same horizontal plane and the uprights 14, 16 are substantially vertical.
- the machine also includes rollers with rubber coating 18, 20 which press the strip of paper against the engraved rollers 10, 12. They are also rotatably mounted around two transverse axes horizontal A3, A4, and are arranged respectively below and above the associated engraved roller 10, 12.
- a first 10 of the engraved rollers and the roller associated rubber coating 18 are mounted on uprights 14 which are articulated around a transverse horizontal axis A5 relative to a frame 22 of the machine so as to be able to disengage the first roller 10 from the second 12.
- the two mobile uprights 14 on which the first roller is mounted 10 thus form a cradle 24 which is capable of pivoting about the axis A5 relative to the frame 22 of the machine from a service position (illustrated in the Figure 1) in an open position.
- the fixed uprights 16 on which the second 12 is mounted of the two engraved rollers are integral with the frame 22 of which they are part integral.
- the coated roller in rubber 18 associated with the first roller 10 is not mounted directly on the cradle 24 but it is integral with the latter by means of two arms 26 which, themselves, are mounted tilting relative to the uprights 14 around an axis horizontal transverse A6 between a service position, illustrated in Figure 1, and an open position in which the rubber-coated roller 18 is not no longer in contact with the first engraved roller 10.
- Each arm 26 is controlled by tilting around its axis A6 by a jack 28.
- each of the two rollers engraved 10, 12 is mounted between the two corresponding uprights 14, 16 by via bearing body 30 which can, for example, provide guidance in rotation, the axial immobilization, the rotational drive, and / or the precise relative positioning of each of the rollers 10, 12 relative to the corresponding amounts 14, 16
- the bearing bodies 30 are themselves in corresponding housings fitted in the uprights 14, 16.
- FIG. 2 illustrates a machine for the mechanical treatment of paper in accordance with the teachings of the invention.
- the position of the axis A5 of pivoting of the cradle 24 has been modified to allow greater opening angle of the cradle 24 towards its released position. So the axis of pivoting A5 has been brought closer to the axis A1 of the first engraved roller 10 which is carried by the cradle 24.
- the uprights 16 linked to the frame 22 have been modified by the addition of a fixed plate.
- the pivot axis A5 of the cradle 24 is arranged substantially in a vertical plane passing through the axis A1 of the first roller 10 and below it.
- An actuator cylinder 29 has been mounted between the fixed frame and the cradle. This cylinder has the function of ensuring the pivoting of the cradle between the positions of service and clear.
- the uprights 14, 16 of the machine have been modified in such a way so that the housings in which are received the bearing bodies which support each of the engraved rollers 10, 12 are partially delimited by removable flanges 36.
- the bearing body 30 forms an assembly which is axially crossed by the axial ends of a central shaft of each of the two rollers 10, 12.
- a part at least 40 of the bearings 30 is engaged in a housing 42 arranged in the side while a second part 42 of the bearing 30 may for example protrude transversely to outside compared to the amount considered.
- part 40 of the bearing body 30 which is received in the housing 42 is cylindrical so that the housing 42 has a complementary cylindrical shape
- One half of the cylinder is delimited in the corresponding flank, while the other half of the cylinder is delimited by a cylindrical arc face 46 of the removable flange correspondent 36.
- the plane of connection of the two surfaces in arc of cylinder which delimit the housing 42 is vertical so that, in this case, the flange transverse can be dismantled radially in a direction substantially horizontal with respect to the axis A1, A2 of the roll 10, 12 concerned.
- the housing 42 When the flange 36 is removed, the housing 42 thus has a opening which is oriented radially, which extends transversely over the whole the thickness of the upright, and through which the bearing body 30 can be engaged or released in this radial direction.
- the two engraved rollers 10, 12 are thus mounted so that they can be radially disengaged with their bearing bodies 30 thanks to the removable flanges 36.
- the jacks 28 are kept depressurized and the cylinder 29 is put into action to tilt the cradle around its axis A5.
- the cradle 24 is brought back by the jacks 29 to its position service so that the housings 42 of the cradle 24 are arranged facing each other of the second roller 20.
- each housing 42 which is normally closed by the flange 36, is defined in particular by a guide edge.
- the guide edges of the openings of two housings facing each other are arranged substantially parallel to one another when the flanges 36 are removed.
- the cradle 24 having been previously returned to the position of service as shown in figure 5 it is possible to move horizontally the second roller 12 with its bearing bodies 30 in the direction of housings 42 arranged in the mobile uprights 14 of the cradle 24.
- the cradle 24 bringing the cradle 24 towards its clear position, it is particularly easy to handle the second roller 12 with its bearing bodies 30 to remove them from the machine.

Description
L'invention se rapporte à une machine pour le traitement mécanique du papier notamment pour le gaufrage et l'assemblage de deux bandes continues de papier absorbant tel que l'ouate de cellulose, comportant des moyens perfectionnés de support d'un rouleau ainsi qu'à un procédé de remplacement des rouleaux d'une telle machine.The invention relates to a machine for the mechanical treatment of paper especially for embossing and assembling two continuous strips of absorbent paper such as cellulose wadding, comprising means support for a roll as well as a method for replacing rollers of such a machine.
L'invention concerne plus particulièrement une machine pour le traitement mécanique du papier, du type dans lequel deux bandes de papier passent chacune entre deux rouleaux de gaufrage cylindriques, l'un lisse à revêtement en caoutchouc, l'autre gravé, par exemple en acier. Les deux cylindres gravés sont d'axes transversaux parallèles, sont montés chacun à rotation autour de leur axe entre deux montants de la machine, et sont agencés tangentiellement l'un contre l'autre, La machine est du type dans lequel un premier des rouleaux gravés est monté à rotation sur un berceau qui est susceptible de pivoter par rapport à un bâti fixe de la machine sur lequel est monté à rotation le second rouleau gravé, et du type dans lequel chaque rouleau gravé est monté à rotation par l'intermédiaire de corps de palier qui sont agencés à chacune des extrémités du rouleau et qui sont fixés dans des logements correspondants aménagés dans les montants respectivement du bâti fixe et du berceau pivotant.The invention relates more particularly to a machine for mechanical paper processing, of the type in which two strips of paper each pass between two cylindrical embossing rollers, one smooth rubber coating, the other engraved, for example steel. Both engraved cylinders have parallel transverse axes, each mounted at rotation about their axis between two uprights of the machine, and are arranged tangentially against each other, The machine is of the type in which a first of the engraved rollers is rotatably mounted on a cradle which is likely to pivot relative to a fixed frame of the machine on which is rotatably mounted the second engraved roller, and of the type in which each roller engraved is rotatably mounted by means of bearing bodies which are arranged at each end of the roller and which are fixed in housings correspondents fitted in the uprights of the fixed frame and the swivel cradle.
On a ainsi illustré sur la figure 1 une partie d'une machine pour le traitement mécanique du papier de type connu. Elle comporte deux rouleaux cylindriques gravés, chacun monté tournant autour d'un axe transversal horizontal entre deux montants verticaux de la machine qui s'étendent chacun dans des plans perpendiculaires aux axes des rouleaux. Chacun des rouleaux comporte un arbre central dont une extrémité est montée par l'intermédiaire d'un corps de palier dans un logement du montant correspondant. Le corps de palier peut par exemple assurer à la fois le guidage en rotation du rouleau et son immobilisation selon la direction transversale. Il peut aussi porter les moyens d'entraínement en rotation du rouleau et/ou des moyens de réglage précis de la position de l'axe du rouleau afin de maítriser notamment l'écartement des deux rouleaux gravés ou leur position axiale relative.We have thus illustrated in FIG. 1 a part of a machine for mechanical treatment of known type paper. It has two rollers cylindrical engraved, each mounted rotating around a transverse axis horizontal between two vertical uprights of the machine which each extend in planes perpendicular to the axes of the rollers. Each of the rollers has a central shaft, one end of which is mounted via a bearing housing in a housing of the corresponding amount. The bearing body can for example ensure both the guiding in rotation of the roller and its immobilization in the transverse direction. It can also carry the means drive in rotation of the roller and / or means for precise adjustment of the position of the axis of the roller in order to control in particular the spacing of the two engraved rollers or their relative axial position.
Lorsque l'on souhaite procéder au remplacement des rouleaux gravés, soit en vue de leur maintenance ou en vue de les remplacer par des rouleaux permettant d'obtenir un motif de gaufrage différent, l'opération se révèle longue et délicate.When you want to replace the engraved rollers, either for maintenance or to replace them with rollers to obtain a different embossing pattern, the operation is long and delicate.
En effet, il est nécessaire de démonter le ou les anciens rouleaux, ce qui nécessite la dépose simultanée des corps de palier. Le remontage de l'ensemble constitué par les corps de palier et par le ou les rouleaux de remplacement est ensuite une opération longue et minutieuse du fait des multiples réglages nécessaires.Indeed, it is necessary to disassemble the old roller (s), which requires the simultaneous removal of bearing housings. The reassembly of the whole constituted by the bearing bodies and by the replacement roller (s) is then a long and meticulous operation due to the multiple settings required.
L'invention a pour objet de proposer une nouvelle conception d'une machine pour le traitement mécanique du papier qui permet de procéder à un changement plus rapide des rouleaux gravés, ceci notamment dans le but de limiter la durée de ce remplacement, durée pendant laquelle la production de la machine est bien entendu arrêtée.The object of the invention is to propose a new design for a machine for the mechanical treatment of paper which allows to carry out a faster change of engraved rollers, in particular for the purpose of limit the duration of this replacement, during which time the production of the machine is of course stopped.
Dans ce but, l'invention propose une machine du type décrit précédemment, caractérisée en ce que les corps de paliers de l'un au moins des rouleaux gravés sont fixés dans des logements qui sont délimités au moins en partie par une bride démontable qui, lorsqu'elle est démontée, libère une ouverture radiale au travers de laquelle le corps de palier peut être dégagé du logement selon une direction radiale, et en ce que le berceau qui porte un des rouleaux gravés pivote autour d'un axe transversal parallèle aux axes des rouleaux entre une position de service, dans laquelle les deux rouleaux sont tangents, et une position dégagée pour le démontage des rouleaux gravés,To this end, the invention provides a machine of the type described previously, characterized in that the bearing bodies of at least one of the engraved rollers are fixed in housings which are delimited at least in part by a removable flange which, when disassembled, releases a radial opening through which the bearing housing can be released from the housing in a radial direction, and in that the cradle which carries one of the engraved rollers pivots around a transverse axis parallel to the axes of rollers between a service position, in which the two rollers are tangents, and a clear position for dismantling the engraved rollers,
Selon d'autres caractéristiques de l'invention :
- l'ouverture radiale des logements s'étend sur toute l'épaisseur des montants selon la direction transversale des axes des rouleaux ;
- les deux rouleaux gravés sont pourvus de corps de palier fixés dans des logements délimités en partie par des brides démontables ;
- les montants du berceau et du bâti sont agencés sensiblement dans un même plan perpendiculaire aux axes transversaux des rouleaux, et, lorsque les brides sont démontées, les ouvertures des logements des montants du bâti et du berceau débouchent radialement l'une en regard de l'autre ;
- en position de service du berceau, chacun des montants du berceau est sensiblement juxtaposé à un montant du bâti, et les ouvertures de leurs logements présentent chacune un bord de guidage qui est agencé dans le prolongement d'un bord de guidage de l'ouverture du montant juxtaposé.
- Un actionneur est fixé d'un côté sur le bâti fixe et de l'autre à un montant du berceau. Il assure le pivotement du berceau par rapport au bâti fixe entre la position de service et la position dégagée.
- the radial opening of the housings extends over the entire thickness of the uprights in the transverse direction of the axes of the rollers;
- the two engraved rollers are provided with bearing bodies fixed in housings delimited in part by removable flanges;
- the uprights of the cradle and the frame are arranged substantially in the same plane perpendicular to the transverse axes of the rollers, and, when the flanges are dismantled, the openings in the housings of the uprights of the frame and the cradle open out radially, one facing the other;
- in the cradle service position, each of the uprights of the cradle is substantially juxtaposed with an upright of the frame, and the openings in their housings each have a guide edge which is arranged in the extension of a guide edge of the opening of the amount juxtaposed.
- An actuator is fixed on one side to the fixed frame and on the other to an upright of the cradle. It pivots the cradle relative to the fixed frame between the service position and the released position.
L'invention se rapporte aussi à un procédé de remplacement des rouleaux
gravés d'une machine pour le traitement mécanique du papier incorporant l'une
quelconque des caractéristiques précédentes,
caractérisé en ce que le procédé comporte les étapes consistant à :
- commander le pivotement du berceau vers sa position dégagée ;

- ramener le berceau vers sa position de service ;
- retirer le second rouleau gravé en dégageant ses corps de paliers radialement au travers de l'ouverture de leurs logements dans les montants.
characterized in that the method comprises the steps consisting in:
- control the pivoting of the cradle towards its released position;
- remove the clamps from the cradle uprights (24);
- remove the first engraved roller by releasing its bearing bodies radially through the opening of their housings in the uprights;
- dismantle the flanges of the uprights of the frame;
- return the cradle to its service position;
- remove the second engraved roller by releasing its bearing bodies radially through the opening of their housings in the uprights.
Selon d'autres caractéristiques du procédé selon l'invention ;
- pour retirer le second rouleau, on dégage celui-ci radialement en amenant chacun de ses corps de paliers du logement du montant du bâti à celui du montant du berceau, le long des bords de guidage des ouvertures en regard, et on amène le berceau une seconde fois vers sa position dégagée pour permettre au second rouleau gravé d'être retiré ;
- les rouleaux gravés de remplacement sont munis de leurs propres corps de palier.
- to remove the second roller, the latter is released radially by bringing each of its bearing bodies from the housing of the upright of the frame to that of the upright of the cradle, along the guide edges of the facing openings, and the cradle is brought one second time to its cleared position to allow the second engraved roller to be removed;
- replacement engraved rollers have their own bearing housings.

On a illustré sur la figure 1 de manière schématique une partie d'une
machine pour le traitement mécanique du papier, plus particulièrement une partie
de la machine destinée à assurer le gaufrage et l'association de deux bandes de
papier qui passent entre deux rouleaux cylindriques gravés 10, 12, lesquels sont
montés chacun à rotation autour d'un axe, respectivement A1, A2, entre des
montants verticaux 14, 16 qui sont agencés dans des plans perpendiculaires aux
axes A1, A2, aux deux extrémités axiales des rouleaux 10, 12.FIG. 1 schematically illustrates part of a
machine for the mechanical processing of paper, more particularly a part
of the machine intended to ensure the embossing and the association of two strips of
paper which pass between two engraved
Dans l'exemple de réalisation illustré sur les figures, les deux axes A1,
A2 sont agencés dans un même plan horizontal et les montants 14, 16 sont
sensiblement verticaux.In the embodiment illustrated in the figures, the two axes A1,
A2 are arranged in the same horizontal plane and the
La machine comporte aussi des rouleaux à revêtement en caoutchouc 18,
20 qui permettent de presser la bande de papier contre les rouleaux gravés 10,
12. Ils sont eux aussi montés à rotation autour de deux axes transversaux
horizontaux A3, A4, et sont agencés respectivement en dessous et au-dessus du
rouleau gravé associé 10, 12.The machine also includes rollers with
De manière connue, un premier 10 des rouleaux gravés et le rouleau à
revêtement en caoutchouc associé 18 sont montés sur des montants 14 qui sont
articulés autour d'un axe horizontal transversal A5 par rapport à un bâti 22 de la
machine de manière à pouvoir dégager le premier rouleau 10 du second 12.In known manner, a first 10 of the engraved rollers and the roller
associated
Les deux montants mobiles 14 sur lesquels est monté le premier rouleau
10 forment ainsi un berceau 24 qui est susceptible de pivoter autour de l'axe A5
par rapport au bâti 22 de la machine d'une position de service (illustrée à la
figure 1) à une position dégagée.The two
Au contraire, les montants fixes 16 sur lesquels est monté le second 12
des deux rouleaux gravés sont solidaires du bâti 22 dont ils font partie
intégrante.On the contrary, the
Comme on peut le voir sur la figure 1, le rouleau à revêtement en
caoutchouc 18 associé au premier rouleau 10 n'est pas monté directement sur le
berceau 24 mais il est solidaire de celui-ci par l'intermédiaire de deux bras 26
qui, eux, sont montés basculants par rapport aux montants 14 autour d'un axe
transversal horizontal A6 entre une position de service, illustrée à la figure 1, et
une position écartée dans laquelle le rouleau à revêtement en caoutchouc 18 n'est
plus au contact du premier rouleau gravé 10. Chaque bras 26 est commandé en
basculement autour de son axe A6 par un vérin 28.As can be seen in Figure 1, the coated roller in
Ainsi que cela est schématisé sur la figure 1, chacun des deux rouleaux
gravés 10, 12 est monté entre les deux montants 14, 16 correspondants par
l'intermédiaire de corps de palier 30 qui peuvent assurer par exemple le guidage
en rotation, l'immobilisation axiale, l'entraínement en rotation, et/ou le
positionnement relatif précis de chacun des rouleaux 10, 12 par rapport aux
montants correspondants 14, 16As shown schematically in Figure 1, each of the two rollers
engraved 10, 12 is mounted between the two

aménagés dans les montants 14, 16.The bearing
On a illustré sur la figure 2 une machine pour le traitement mécanique du papier conforme aux enseignements de l'invention. FIG. 2 illustrates a machine for the mechanical treatment of paper in accordance with the teachings of the invention.
Comme on peut le voir sur cette figure, la position de l'axe A5 de
pivotement du berceau 24 a été modifiée de manière à permettre un plus grand
angle d'ouverture du berceau 24 vers sa position dégagée. Ainsi, l'axe de
pivotement A5 a été rapproché de l'axe A1 du premier rouleau gravé 10 qui est
porté par le berceau 24. Pour ce faire, dans l'exemple représenté, les montants 16
liés au bâti 22 ont été modifiés par le rajout d'une platine fixe.As can be seen in this figure, the position of the axis A5 of
pivoting of the
L'axe A5 de pivotement du berceau 24 est agencé sensiblement dans un
plan vertical passant par l'axe A1 du premier rouleau 10 et en dessous de celui-ci.The pivot axis A5 of the

vérin a pour fonction d'assurer le pivotement du berceau entre les positions de
service et dégagée.An
Par ailleurs, les montants 14, 16 de la machine ont été modifiés de telle
manière que les logements dans lesquels sont reçus les corps de palier qui
supportent chacun des rouleaux gravés 10, 12 sont délimités en partie par des
brides démontables 36.Furthermore, the
En effet, comme cela est illustré à la figure 3, le corps de palier 30
forme un ensemble qui est traversé axialement par les extrémités axiales d'un
arbre central de chacun des deux rouleaux 10, 12. Une partie au moins 40 des
paliers 30 est engagée dans un logement 42 aménagé dans le flanc tandis qu'une
seconde partie 42 du palier 30 peut par exemple dépasser transversalement à
l'extérieur par rapport au montant considéré.Indeed, as illustrated in FIG. 3, the bearing
Dans l'exemple de réalisation illustré sur les figures, la partie 40 du
corps de palier 30 qui est reçu dans le logement 42 est cylindrique si bien que le
logement 42 présente une forme cylindrique complémentaire Une moitié du
cylindre est délimitée dans le flanc correspondant, tandis que l'autre moitié du
cylindre est délimitée par une face en arc de cylindre 46 de la bride démontable
correspondante 36.In the embodiment illustrated in the figures,
Par exemple, le plan de liaison des deux surfaces en arc de cylindre qui
délimitent le logement 42 est vertical si bien que, dans ce cas, la bride
transversale peut être démontée radialement selon une direction sensiblement
horizontale par rapport à l'axe A1, A2 du rouleau 10, 12 concerné.For example, the plane of connection of the two surfaces in arc of cylinder which
delimit the
Lorsque la bride 36 est retirée, le logement 42 présente ainsi une
ouverture qui est orientée radialement, qui s'étend transversalement sur toute
l'épaisseur du montant, et au travers de laquelle le corps de palier 30 peut être
engagé ou dégagé selon cette direction radiale.When the
Dans l'exemple de réalisation de l'invention qui est illustré sur les
figures, les deux rouleaux gravés 10, 12 sont ainsi montés pour pouvoir être
dégagés radialement avec leurs corps de palier 30 grâce aux brides démontables
36. Toutefois, on peut envisager de n'équiper qu'un seul des deux rouleaux de
brides démontables 36.In the embodiment of the invention which is illustrated on the
figures, the two
Grâce à l'invention, il n'est plus nécessaire de procéder au démontage
séparé des paliers 30 et du rouleau, et l'extraction du rouleau s'en trouve ainsi
grandement facilité.Thanks to the invention, it is no longer necessary to disassemble
separated from the
On a illustré sur les figures 4 à 6 différentes étapes de l'opération de
remplacement des cylindres 10, 12 d'une machine selon l'invention.We illustrated in Figures 4 to 6 different stages of the operation of
replacement of the
A l'étape de la figure 4, les vérins 28 sont maintenus hors pression et le
vérin 29 est mis en action pour faire basculer le berceau autour de son axe A5.In the step of FIG. 4, the
Il est alors possible de démonter les brides 36 qui maintiennent les corps
de palier 30 du premier rouleau gravé 10 sur le berceau 24 et le rouleau 10 peut
alors être dégagé radialement hors des logements 42 aménagés dans les montants
mobiles 14.It is then possible to disassemble the
A l'étape illustrée à la figure 5, après avoir démonté les brides 36 des
montants fixes 16, le berceau 24 est ramené par les vérins 29 vers sa position de
service de manière que les logements 42 du berceau 24 soient disposés en regard
du second rouleau 20.In the step illustrated in FIG. 5, after having dismantled the
En effet, lorsque leurs brides 36 sont démontées, les logements 42
aménagés pour les corps de palier 30 dans chacun des montants 14, 16 sont
découpés de telle sorte que, lorsque le berceau 24 est en position de service, ils
débouchent radialement l'un en regard de l'autre., L'ouverture de chaque logement
42, qui est normalement obturée par la bride 36, est définie notamment par un
bord de guidage. Les bords de guidage des ouvertures de deux logements en vis-à-vis
sont agencés sensiblement parallèlement dans le prolongement l'un de l'autre
lorsque les brides 36 sont démontées. Eventuellement on peut prévoir une pièce
mobile formant un pont entre les deux bords.When their
De la sorte, le berceau 24 ayant été préalablement ramené en position de
service ainsi que cela est illustré à la figure 5, il est possible de déplacer
horizontalement le second rouleau 12 avec ses corps de palier 30 en direction des
logements 42 aménagés dans les montants mobiles 14 du berceau 24. Ainsi,
comme on peut le voir à la figure 6, en ramenant ensuite le berceau 24 vers sa
position dégagée, il est particulièrement aisé de manipuler le second rouleau 12
avec ses corps de palier 30 pour les enlever de la machine.In this way, the
Bien entendu, l'opération de remontage des rouleaux de remplacement s'effectue dans l'ordre inverse.Of course, the operation of reassembling the replacement rollers is done in reverse order.
Grâce à l'invention, il est possible d'équiper les rouleaux de remplacement de leurs corps de palier avant de procéder à l'opération de remplacement proprement dite, c'est-à-dire sans que cette étape allonge la durée d'immobilisation de la machine au cours de laquelle sa production est arrêtée. Thanks to the invention, it is possible to equip the rollers with replacement of their bearing housings before proceeding with the actual replacement, i.e. without this step extending the duration machine downtime during which its production is stopped.
Cette phase, particulièrement délicate, peut donc se faire en temps masqué.This particularly delicate phase can therefore be done in time mask.
Par ailleurs, l'invention peut être aisément mise en oeuvre sur des machines existante du type de celle illustrée à la figure 1.Furthermore, the invention can be easily implemented on existing machines of the type shown in Figure 1.
