Definitions
- the present invention relates to a device for fixing of a sleeve on an axis of a plate cylinder of a printing machine.
- the plate cylinders of machines print usually consist of a tree cylindrical or conical, on which a sleeve is fixed bearing, on its external peripheral part, the engraving intended for printing.
- the deformation of the sleeve is usually obtained by blowing pressurized air between the internal surface of the latter and the outer surface of the tree, through small diameter holes provided in the latter.
- the object of the invention is to propose a means allowing securing a printing sleeve on its shaft on the one hand, avoiding the deformation of the sleeve and, on the other hand, of having to maintain the hydraulic pressure ensuring that the sleeve remains on its tree during operation.
- the means capable of ensuring the deformation of the deformable zones sheath are made up of means allowing to exercise an overpressure on the external face thereof.
- the means capable of ensuring the deformation consist of means for exerting a depression on the face internal sheath closing the cavities.
- the cavities are made up of recesses made over the entire periphery of the outer surface of the tree, and the surfaces support are made up of cylindrical surfaces of narrow width.
- each cavity is in communication with a longitudinal channel provided in the tree, this channel itself being in communication with suction means, so as to create a controlled vacuum in the volume delimited by each cavity and the internal surface in look of the scabbard.
- the outer surface of the sheath can also be hollowed out, opposite each of the holding surfaces, with a recess whose depth is such that when the sleeve is in assembly position, the outer surface of this next to the holding surface is located substantially in line with its external surface located next to the cavities.
- the device according to the invention is consisting of a cylindrical shaft 1 with a longitudinal axis xx 'which is intended to support and drive an anilox sleeve 3.
- the shaft 1 has, at each of its ends, dolls 5.5 'intended to ensure its maintenance and training in rotation.
- the shaft 1 is hollowed out, on its periphery, with several cavities 7 of annular section, which are each in communication, via a radial duct 9, with a channel longitudinal 11 which opens at one end of the shaft 1, these cavities being separated by retaining surfaces 12 uncut cylindrical.
- a thin sheath 2 is fitted onto the holding surfaces 12 of the shaft 1. This sheath is made of epoxy resin reinforced with fibers of glass.
- the shaft 1 is hollowed out with a second longitudinal channel 13 which is axial and which also opens at one end of tree 1.
- Channel 13 is in communication with five radial conduits 15 which open onto the periphery of shaft 1, in a small cylindrical bowl 17 dimension.
- the sleeve 2 is drilled, opposite each conduit 15, an orifice 18.
- the shaft 1 is hollowed out by two circular grooves 19 in which are placed O-rings 21.
- Another O-ring 21 ' is arranged in a circular groove 19' to the other end of shaft 1.
- the sleeve 3 consists in particular of a metal, by example of aluminum. It can also consist of synthetic materials using a structure especially honeycomb, so as to have a large rigidity.
- the deformation of the sheath 2 is facilitated by the fact that the volumes V, comprised between the internal walls of each cavity 7 and the internal face of the deformable parts 25 sleeve 2, are maintained at atmospheric pressure by the conduits 9 and the channel 11. In fact, the pressurized air injected through the orifices 18 can not enter these volumes V due to the presence of O-rings 21 and 21 '.
- the present invention thus makes it possible to produce a removable locking of a sleeve, and in particular of a sleeve anilox, on its drive shaft, without causing deformation on the upper surface of this sleeve.
- this device ensures such blocking, without that it is necessary, during operation, to put using hydraulic pressure maintenance means.
- Such a device is thus particularly suitable to secure the attachment to a drive shaft of rigid aluminum anilox sleeves coated with ceramic, which have the advantage of being easy to carry out but which does not can be used only on sleeves which do not undergo, on the surface, strictly no deformation under penalty of crack the ceramic.

Description
- il comporte, entre le manchon et l'arbre, un fourreau déformable,
- la surface de l'arbre est creusée d'une série de cavités, séparées par des surfaces de maintien sur lesquelles le fourreau est en appui,
- le fourreau est apte à se déformer de façon qu'il puisse posséder deux positions, à savoir une position d'assemblage, dans laquelle au moins une partie de sa surface, dite zone déformable, à savoir celle située en regard des cavités, se déforme dans celles-ci sous l'action d'une contrainte, et une position de repos dans laquelle la zone déformable a repris, au moins en partie, sa forme initiale, de façon à être appliquée contre la surface interne du manchon,
- il comporte des moyens aptes à assurer la déformation dans le sens radial des zones déformables du fourreau.
