Definitions
- TITLE DEVICE FOR PRINTING SPHERICAL OBJECTS AND THE LIKE
- the invention relates to a device for printing on threedimensional 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 it 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 whichthe stamp is made; therefore, it can only reach very small surface areas.
- this feature is achieved with a novel design of stamp i.e. the solution has been achieved by breaking with the traditional moulds which have a solid stamp, and by developing a new design according to which said stamp comprises a flexible hollow body.
- said flexible hollow stamp takes the form of a thin hemispherical hood which is fixed round its rim to a plate held by mechanical means which perform the appropriate raising and lowering movements onto the object to be printed.
- the hollow interior of the stamp and its inherent flexibility enable it to conform to any solid object and also to the flat surface of the master where the ink is collected.
- the stamp of the present invention is lowered onto the inked master design disposed on a flat surface and is pressed against it, it is flattened agatint the master and picks up the inked design correctly.
- the hollow stamp When this inked design is separated from the flat master, the hollow stamp recovers its intitial shape as a hemisphere and, when it is placed on the spherical object to be printed and is pressed against it, its hollow form and flexibility again enable it to adapt to the spherical form of said object, surrounding it practically as a hemisphere and printing the corresponding design onto this surface.
- the hollow flexible stamp can be filled with some material which, by enabling it to deform precisely, provides it with the proper consistency and, moreover assists it to recover its form elastically after each deformation.
- said filling material will preferably be a fluid.
- the object being, printed may be spherical or any other three-dimensional shape as the invention is valid for printing the concave and the convex parts of an object where it is also suitable for printing hemispherical and semicylindrical interiors and the like.
- Figure 1 is an elevation of a pair of stamps which are ready to operate on respective spherical objects
- Figure 2 is a view similar to that of Figure 1 but with the stamps in contact with the objects to be printed;
- Figure 3 is a section of the stamp taken on the line III - Ill of Figure 1
- Figure 4 is a section of the stamp taken on the line IVIV of Figure 1.
- Explanatory details 1.
- - Stamp 2. - Hemispherical hollow stamp body
- 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 whic.h incorporates the inked design which is to be printed.
- 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) rises and moves until it is over the object to be printed (5) as shown in Figure 1.
- 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.
- the stamp (1) may incorporate a 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 will preferably be a fluid, either gaseous or liquid, which will leave the body (2) when the latter deforms and return to the inside of the body automatically when the deformation ceases.
- this filling matrial could be a solid or particulate having sufficient elasticity without in any way altering the essence of the invention.
- 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 or may even be flat, although it is clear that,the invention has been specifically designed in order to print three-dimensional objects.
- These objects (5) can have a convex or else concave form in the external configuration of their surface to be printed.
- the fundamental shape of the body (2) of the stamps (1) may be spheroid, cylindrical or cylindroid etc., without departing from the scope of the invention as defined in the following claims.

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.Method and device for printing on three-dimensional objects, characterized in that the member for transferring the inked pattern between a flat main surface from which said pattern is taken and a three-dimensional object on which it is necessary to perform the impression is formed by an elastically deformable hollow stamp (1) preferably having a hemispherical shape and which can deform, when pressed against the original, to form a flattened surface which ensures inking and which can deform, when it is pressed against a three-dimensional object (5) to be printed, in order to wrap the object on an essentially hemispherical surface, surface intended to receive the inked pattern.
