Abstract

The composite pictures are formed from two separate images. The first image is initially cut and placed upright against a guide which has an upper horizontal edge of multiple strips sliding in each other. Then, on the reverse of the first image is placed adhesive and the guide is tilted to an appropriate angle. This forms longitudinal facets from the guide strips. A module which is the final support of the image is then applied to the faceted surface.

Description

  The present invention relates to a process for obtaining faceted composite images, from two separate image elements, the invention also relating to an apparatus for implementing said process, as well as to the product obtained by the process according to the

  vention and on the use of said product.

  We already know faceted images such that when we look at them alternately on one side, then on the other, from a certain angle, we reveal two different images, such as, for example, that the portrait of a person having a certain expression on one side and a different expression on the other side. Such images are generally obtained by optical devices such as, for example, the affixing on the image in question of a transparent surface made up of small identical longitudinal prisms successively crossing the

to each other.

  The object of the present invention is to obtain facet images with direct vision, in other words without any optical device, said images having one side.

  ribbed composed of longitudinal facets, inclined al-

  ternatively from a certain angle on one side, then, symmetri-

  only, on the opposite side, with respect to the perpetual direction

  dicular to the average surface of said image. The facets oriented on the same side of this image each comprise, successively, one of the bands of each of the elements

  images, bands in which said element was previously

badly cut.

  The method according to the invention aims to obtain faceted composite images from two distinct image elements, characterized in that firstly, the first image element is cut out, element placed

  front side, against an appropriate guide, composed of horizontal edges

  upper zontals of a plurality of juxta- parallel blades

  placed and capable of sliding on each other, said cutting being carried out in narrow strips, in the direction

  longitudinal, each strip having the width of the horizontal edge

  zontal of a blade, the method according to the invention being further characterized in that in a second step, an adhesive means is applied to the back side of said first image element, in that in a third step, the d 'an appropriate angle said guide so as to form by said upper edges of its blades a surface with longitudinal facets, alternately symmetrical to each other with respect to

  to the direction of the vertical to the middle plane of the image, pro-

  yielded further characterized in that in a fourth step, is applied to the faceted surface of the guide thus obtained, all of which oriented transversely towards one of the sides of the image each carry a strip of said first image element, a module, which is the final support for the image sought! module also made up of facets and the surface of which is the negative of that of said guide, after tilting of the latter's blades, which causes the successive strips, already glued, of said first image element, to adhere, each, on: the facet which corresponds to it from the surface of said module, thus completely releasing said guide, the method according to the invention being furthermore characterized in that, in a fifth and last step, we start again,

  with the second image element, the succession of operations

  tions described in the first four execution times of the process, the successive bands of this second

  image element coming to be fixed on the corresponding facets

Rims, remaining free, of the module.

  The apparatus for carrying out the process-

  according to the invention comprises in the first place: a guide composed of the horizontal upper edges of a plurality of juxtaposed vertical parallel blades carried by a common frame, blades capable of sliding against each other until the horizontal surface resulting decomposes into successively symmetrical longitudinal facets

  others with respect to the perpendicular vertical direction-

  in the mean plane of said surface, the apparatus according to the invention being further characterized in that it comprises a module which

  constitutes the definitive support of the faceted image sought-

  chée, module whose surface intended to be applied against that, also faceted, of said guide, after tilting, constitutes the negative of this latter surface. The invention also relates to the product obtained by the process according to the invention, product comprising an image with facets juxtaposed longitudinally and inclined alternately at approximately + 450 and at approximately - 450 relative to the mean horizontal plane of said image, the successive facets oriented on a mime bearing side, fixed on each of them, a longitudinal strip of a

of the two elements of the image.

  The invention finally relates to the use of

  product obtained by the process according to the invention, used

  tion as decorative object, artistic object, object with relief effects, advertising medium, toy, object of curiosity and amusement, as well as use for all

  purposes using the faceted structure of said product.

  The invention has many advantages, in particular the simplicity, speed and precision of the various operating phases, as well as the certainty of obtaining an impeccable product each time, which is far from being the case in operations making , especially,

call for collages.

  The invention also allows a very wide choice of parameters of the image to be obtained, in particular the width and even the inclination of the facets of this image, which precisely allows a very wide range of use.

as already specified.

  In what follows, we will describe, in broad outline, successively, the process, the apparatus and the product.

according to the invention.

  With regard to the method, the prior choice of the format of the image sought, conditions to a certain extent the size of the whole of the apparatus for implementing the method, it being understood that it is always possible, within certain limits, to make the parts of this device interchangeable, by

  function precisely of the dimensions of the final image sought-

  chée. The format of said image corresponds to that of each of the two image elements that are

  proposes to juxtapose, by narrow strips previously de-

cut, in the final image.

  A guide is then formed for said image, this guide consisting of the upper horizontal edges of a plurality of juxtaposed vertical blades carried by a common frame and capable of assuming, from their starting vertical positions, a position inclined at approximately 450 compared to the first one, so that the edges

  upper blades, initially forming a horizontal surface

  zontale, present after displacement a crenellated surface composed of as many facets as there are blades, facets oriented alternately on one side, then on the other, perpendicular to the mean plane of the image and intended to carry each a strip previously cut in the

  first and second elements of the final image.

  Care is taken to properly cut each of said two image elements to the contours of the composite image.

  sought, this-leaving a certain margin for fixing

  tion of the image, as set out below.

  We start by placing the first image element, its front side against re guide, taking care to center the image on the position that will come to occupy, when the time comes,

  a suitable mold. In order to ensure good fixity to the element

  ment thus posed during the cutting, one calls of prefe

  rence to an adhesive means such as a sticky tape of sufficient width to cover both the aforementioned margin, and part of the picture element. This fixation is presented

  transversely to the movement of the knives which will have to

  cut into strips the image thus fixed.

  The back of said first image element is then glued, this gluing can be done by

  all known means, such as brushes, rollers, etc.

  However, to avoid clogging of the knives with glue during cutting, as well as all kinds of burrs occurring during operation, gluing is carried out, preferably by means of a known product and consisting of a strip of paper on which a double-sided sticky element has been fixed, the whole being under

  roller shape for easier handling.

  The back of the first image element is therefore covered with this strip of paper carrying the double-sided adhesive element on the side of said back of the image on

  which this element strongly adheres to.

  We then proceed to cutting, being careful to slightly cut the different blades of the guide

  to allow passage to the cutting knives.

  In doing so, we remove the first transverse sticky strip which hitherto fixed said image element and we use an appropriate flap to properly apply

  the upstream side of the double-sided adhesive support against the guide.

  We can then proceed to cutting. The flap is then removed and the paper support is removed, leaving only the double-sided adhesive element in place, which therefore adheres perfectly to the back of the first

  picture element and remains free, on its upper adhesive surface

  to allow the subsequent fixing of each of the

  bands of the image, thus left bare, on the corresponding facet

  of the module, which actually represents the final object

that we propose to decorate.

  The cut made, the set of guide blades is tilted, by the translational maneuver of the frame which supports them, and so that the upper faces of the blades, until then constituting the initial horizontal plane of said guide , are inclined at about 45 relative to this same plane, the whole thus forming a crenellated surface

  made up of longitudinal facets, oriented successively

  on one side, then on the other.

  This done, the module thus applied is applied to the said module, by exerting on it sufficient pressure so that the different strips, each covered with the adhesive element, are applied to the successive facets of the said modules. To this end, said module also has a crenellated faceted surface.

  which represents, in fact, the negative of the corresponding surface

of the aforementioned guide.

  It is free, in case the outer circumference

  of the final image differs from that of the guide, remaining natural-

  lementscribed inside the contour of the latter, -e practice, on the upper edge of each of the blades of said guide, a grooving and this in such a way that the total bleeding obtained on the surface of said guide precisely corresponds to the contour desired that we can thus cut using an appropriate cutting tool, penetrating said groove. In order to allow correct cutting of the lateral edges of each picture element, it is advisable according to the invention to provide an additional blade of each

  side of the guide relative to the number of facets of said module.

  Having proceeded, as has just been said, with the fixing on the facets of the module oriented on one side, of the corresponding bands of the first picture element, it will suffice to proceed in exactly the same way with the second picture element. image, turning only the end for end, the module, so as to make it present its facets which remained free against the edges of the guide strips on which the strips of the second element will have been fixed

the final image.

  The module thus completed can constitute in itself

  even the final decorative object sought. It can also be fixed by any known means on another support chosen in advance, a suitable frame for example, which would then include a housing judiciously designed to contain said module. Said frame can just as easily be a utility object such as an ashtray, a pendulum, a paperweight, etc. The invention can be better understood using

  of the additional description which follows concern

  more particularly the constructive details of the implementation apparatus, with reference to the appended drawings in which: - Figure 1 represents, in perspective view, the whole of the apparatus of use, Figure 2 represents the chassis blade holder, with, engaged in the two slides of said chassis, one of the blades according to the invention,

  - Figure 3 gives the detail of the upper upper end

blade rale,

  - Figure 4 is a plan view of a module according to the invention-

  tion, - Figures 5 and 6 respectively represent the positions taken by the blades of the guide according to the invention, on the one hand in the cutting position, on the other hand in the transfer position,

  towards the module, bands of one of the elements of the image.

  It should however be understood that these drawings and the corresponding descriptive parts are

  given only as an illustration of the subject matter of the

  vention, of which they in no way constitute a li-

  mitation. There is shown in 1, the base of the device, of appropriate dimensions and shape. This base carries

  the various organs of the apparatus as explained below.

  We see at 27, the two support flanges on which the blade holder chassis 21 is caused to move

  transversely to the cutting direction of the bands of the image.

  Reference 28 designates the stop which determines the position of the chassis

  blades 21 during the cutting operation, the blades 22 being dis-

  placed vertically side by side. The reference 19 designates a multiple strike whose notches 24 allow the engagement of the bolts 20 carried by the chassis 21. We see at 25 the flap arranged to pivot around an axis 26 integral with the base 1, to come to bear on the horizontal surface of the guide 23 in the strip cutting position, so as to exert sufficient pressing pressure on the upstream parts of the first and second elementary images, when these are in position cutting. The pivoting movement of said flap takes place according to arrow F1, the flap being in the rest position placed on the base 1. The latter comprises, on an appropriate support 9, a first pivoting arm 2 constituted by parallel rods 8 each articulated around an axis 7

  integral with said support 9. A plurality of knives 3, paral-

  leles and equidistant from each other, is threaded on an axis

  mun 6 carried by two lateral flanges 5 secured each to one of the rods 8. This arm comprises an operating handle

  4 allowing its pivoting movement according to arrow F2.

  We see in 17 -a flange secured to the base 1 and on which comes

  place, in the cutting position, the arm 2 in such a way that the rods 8 come to engage in the corresponding notches 8a. It can thus be seen that during the cutting operation, the knives 3 engage in the interstices

  reserved for this purpose between the different blades 22.

  The base 1 supports, on the other hand, a second pivoting arm 10 comprising rods 13 articulated around the axes 15 carried by the flange 16. we see at 14, the operating handle of said arm 10 whose movement takes place

  according to arrow F3 and which, in the working position, re-

  place, by said rods 13, on two spans 18. Said

  second arm 10 carries a mold 11 on which will be applied

  quer the module 35 shown in plan in Figure 4, and whose surface has the same facets as those of the module 11, these two surfaces being, both, the negative of the surface of the guide in the tilted position, such

as visible in figure 6.

  We see, in Figure 2, the two slides

  29 formed by the U-shaped elements which border trans-

  versally the chassis 21. We see in the same figure, the

  front cross member 30 of frame 21, partially rear cross member

  to show the location of the bolts 20 intended to come and engage in the notches 24 of the keeper 19, in

  tilted position of the blades 22 of the guide 23.

  We see in Figure 3, the manner in which is formed one of the notches 31 formed at each end of the strips 22. Each of these notches is delimited top and bottom by an oblique face, inclined at about 450 on the

corresponding body of the blade.

  we see at 33 a rounded guide finger intended to penetrate inside the corresponding slide 29 of the chassis 21. It is around said finger 33 that the blade 22 concerned is pivoted. We see at 34, an elastic band attached to the upper edge of each blade 22 and intended to improve the contact between the image elements bearing on these bands, firstly when the adhesive medium is applied to them. double-sided then when pasting the image strip concerned on the module, when presenting the latter on the tilted surface, with facets,

of the support 23.

  The user manual of the device which has just been

  described results on the one hand from the detailed description of the

  method according to the invention which preceded, on the other hand, the

  description of the device in question.

  As is clear from the above, the invention

  tion is in no way limited to those of its modes of implementation, production and application which have just been

  described more explicitly; she embraces it,

  milking, all the variations which can come to the mind of the technician in the matter, without departing from the framework, nor from the

scope of the present invention.
