Definitions

  • the invention relates to a device for printing on three-dimensional bodies, and more particularly but not exclusively for printing on spherical or part- spherical bodies, and to a method of printing using such a device.
  • the design solution adopted with said stamps is to make them from solid rubber or similar synthetic materials.
  • This solid form means that, when a spherical object is to be stamped, the adaption of the stamp to the shape of the object takes place solely through elastic deformation of the material of which is is made.
  • the surface area which the stamp can cover is very limited, being confined to small areas.
  • the stamp since the stamp has to be flat in order to be able to take the corresponding inked design from a flat master surface and, since it is solid, adaption of the same to the spherical object takes place solely through elastic deformation of the material of which the stamp is made; therefore, it can only reach very small surface areas.
  • a device for printing three-dimensional objects comprising a flexible stamp for transferring an inked design between a flat master surface from which said design is to be picked up and a three-dimensional object which is to be printed, which stamp, when pressed on to the master, is capable of deformation to provide a flattened surface which allows said pick-up to take place and, when pressed on to a three-dimensional object to be printed, is capable of deformation to envelope the object over a surface area which receives the inked design
  • the flexible stamp having a hollow body the interior of which is occupied by a fluid which allows the stamp to be deformed and assists in the elastic recovery of its original shape characterised in that the stamp is substantially hemispherical and is capable of concave deformation to envelope the object to be printed over a surface area of substantially a hemisphere following flattened deformation over substantially the same area for pick-up of the design, and characterised by means through which the fluid leaves the body during deformation and returns automatically when deformation cease
  • the device is preferably characterised by a plurality of the stamps adapted to operate in synchronism, the interiors of the bodies of the respective stamps being connected together by closed circuit means whereby the fluid can move between the stamps.
  • the invention is a method of printing on the surface of a spherical object using a device as described above, characterised by the steps of pressing the hollow flexible hemispherical stamp against a flat inked master surface whereby the hemispherical surface of the stamp is flattened into surface to surface contact with the stamp so that the design to be printed is transferred to the surface of the stamp, removing the hollow flexible hemispherical stamp from the master surface to permit the stamp to regain its hemispherical shape, pressing the hollow flexible hemispherical stamp against the spherical object so that it envelopes a hemispherical portion of the object and its inked surface is brought into contact with the surface of the object whereby the inked design is transferred to the hemispherical portion of the object.
  • a plurality of the stamps may be used to print different colours on the spherical object.
  • the method is preferably characterised in that, after printing of said hemispherical portion, the spherical object is turned through 180 and printing by a stamp or stamps is effected on the other hemispherical portion of the object.
  • each stamp (1) see Figure 1
  • each stamp (1) is constituted by a body in the form of a hollow flexible hemispherical hood (2) which is fixed to a support structure (3) which in turn is fixed to a rod (4) which may be connected to a conventional means which provides the necessary translation, raising and lowering movements.
  • the hood (2) consists of a laminar hollow elastic element which, starting from its convex external shape, can adapt to any object through the effect of the pressure exerted by the rod (4), conforming its external surface to that of the object to be printed and, consequently, transferring the inked design to an object equivalent in area to a hemisphere in one step.
  • the object (5) to be printed which in this case is a spherical object such as a balloon, is held under the stamp (1) by means of fastening device or support (6).
  • the printing process is as follows:
  • each stamp (1) moves until it is located on the flat master template which incorporates the inked design which is to be printed. In this position, the stamp (1) descends, applying pressure, and, since the stamp (1) is hollow and flexible, it deforms and, as it is flattened against the flat template, it adopts the shape of a flattened hemisphere which, at its pole, provides a flat surface constituting a good recipient for the inked design incorporated on the template.
  • the stamp (1) is then lowered and again, being a hollow flexible body, it deforms and envelopes the object (5) as shown in Figure 2. In this way, it prints the design which it had taken on the flat template on to this object (5) and, through the envelopment of the object (5), said printing can cover practically half of this object (5), i.e. a hemisphere.
  • the stamp (1) will incorporate a fluid filling material in its hollow interior, which material helps to provide the body (2) with required resiliency and helps it recover its initial shape elastically.
  • said filling material either gaseous or liquid, will leave the body (2) when the latter deforms and return to the inside of the body automatically when the deformation ceases.
  • stamping line for spherical objects (5) groups of four stamps (1) will be arranged for the four basic colours of the colour combinations and these four stamps (1) will produce the the corresponding final design which will cover half an object (5), either through successive operation of the same or through simultaneous operation and successive feeding of the objects (5).
  • the description which is given of one possible practical embodiment is not intended- to be taken as limiting since the objects (5) to be printed may have any known three-dimensional shape. These objects (5) can have a convex or else concave form in the external configuration of their surface to be printed or even be flat.

Abstract

Procédé et dispositif permettant d'effectuer une impression sur des objets tridimensionnels, caractérisés en ce que l'organe de transfert du motif encré entre une surface principale plate à partir de laquelle ledit motif est prélevé et un objet tridimensionnel sur lequel il faut effectuer l'impression est consitué par un timbre creux élastiquement déformable (1) présentant de préférence une forme hémisphérique et pouvant se déformer, lorsqu'il est pressé contre l'original, pour former une surface aplatie qui assure l'encrage et pouvant se déformer, lorsqu'il est pressé contre un objet tridimensionnel (5) à imprimer, afin d'envelopper l'objet sur une surface essentiellement hémisphérique, surface destinée à recevoir le motif encré.

Claims (5)

1. Dispositif pour réaliser des impressions sur des objets à trois dimensions, comportant un tampon d'impression flexible pour prélever un motif encré sur une surface d'origine plate, afin de le transférer sur un objet à trois dimensions destiné à être imprimé, ledit tampon, lorsqu'on l'applique sous pression sur la plaque d'origine, étant capable de se déformer pour présenter une surface aplatie qui permet le prélèvement du motif encré alors qu'il peut se déformer lorsqu'on l'applique sous pressi sur l'objet à trois dimensions prévu pour recevoir le motif imprimé, pour envelopper cet objet sur une surface où doit être placé le motif imprimé, ledit tampon flexible (1) ayant un corps creux (2) dont l'intérieur est rempli d'un fluide permettant au tampon de se déformer et facilitant le retour élastique à sa forme originale, caractérisé en ce que le tampon (1 est sensiblement hémisphérique et capable de se déformer en prenant une forme concave pour envelopper l'objet à traiter (5) sur une surface qui correspond sensiblement à une hémisphère, après s'être déformé une premiè fois en s'aplatissant sensiblement suivant une surface de même valeur, po prélever le motif encré, et caractérisé par des moyens par lesquels le fluide sort du corps pendant la déformation et y pénètre à nouveau automatiquement dès que cesse la déformation afin de faciliter la déformation et le retour élastiques du tampon (1).
2. Dispositif pour réaliser des impressions sur des objets à trois dimensions selon la revendication 1, caractérisé par une pluralité de tampons (1) adaptés pour fonctionner en synchronisme, l'intérieur des cor (2) des tampons respectifs étant raccordé l'un à l'autre par des moyens e circuit fermé permettant au fluide de se déplacer d'un tampon à l'autre.
