- This machine 20 can be advantageously used in a method of assembly by bonding the layers of a PMP model.
- the invention also relates to such a method of assembling by bonding layers of a PMP model, thereby obtaining the above advantages.
- Such a method comprises the prior implementations of the first layer 40 and the second layer 60 of the model 50 on the first support 24 and the second support 26 respectively.

- the glue used may have a Brookfield viscosity of between 700 and 1800 mPa.s at the bonding temperature.
- the adhesive used has a Brookfield viscosity of between 1000 and 1500 mPa.s at the bonding temperature.

- the self-centering devices comprise:
- a set of rolling balls allowing displacement in at least one direction contained in the plane orthogonal to the gluing direction;
- An unbalanced bonding surface corresponds, for example, to a bonding surface having more slopes oriented to the right than slopes oriented to the left. Because of the greater number of right-hand slopes, the setting of the strata into position can tend, by reaction, to a left-to-left mapping.
- the orientation of the pair of pushers 38 in two different directions in the same direction makes it possible to rebalance the matching of the strata 40 and 60 during their assembly.

- the assembly formed by the support 24 and the intermediate support 84 corresponds to a gripper shaper or gripper because it is intended to be disposed in the upper part of the machine 20, when the gluing direction is vertical.
- Part of the self-centering members is formed by at least one axis 70 of self-centering.
- the self-centering members comprise four self-centering shafts 70 each arranged at a corner of the first support 24.
- FIG. 9 shows a sectional view, according to the hatched plane P, of the first support 24 and the intermediate support 84. This view corresponds to a section in the plane of the line L of FIG. 8.
- Figures 10A and 10B show a perspective view and an exploded perspective view of the previous self-centering axis 70.
- the axis 70 is composed of two sets of rolling balls 30. These two sets of balls 30 are each held by a cage 72. These sets of balls are also each trapped in a cavity delimited in part by the part 86. On one side the part 86 defines a cavity with the plate 74, and on the other hand, the part 86 defines a cavity with the washer 76. Each of the sets of balls 30 can to slide freely in the plane orthogonal to the gluing while being guided by the piece 86 on the one hand and one of the pieces among the plate 74 and the washer 76 on the other hand.
- the part 86 is fixed to the intermediate support 84 by means of a nut 88 while the plate 74 and the washer 76 are secured to the first support 24, for example by means of screws 78.
- the proposed axis 70 allows displacement in all directions contained in the plane orthogonal to the gluing direction.
- the self-centering members further comprise a spring loaded plunger support at each corner of the support 24.
- These four spring plungers are not visible in Figure 8
- FIGS. 11A and 11B show a perspective view and an exploded perspective view of such a spring-loaded support 32.
- the spring loaded pushers 38 are then received in bores of the support 32 of spring pushers.
- the first support 24 comprises four pairs of spring plungers distributed in two different directions of the plane orthogonal to the bonding. Two pairs of spring plungers distributed in two different directions may suffice, as previously described with reference to the embodiment of Figure 7. However, a greater number of pairs of pushers contributes to the stability of the machine 20. In all case, for a pair of pushers oriented in the same direction, each push of the pair is preferably oriented in a different direction as previously described.
- the spring pushers 38 may be chosen at least from the spring pushers 38 with balls or with fingers, FIGS. 12A and 12B show sectional views of these two modes.
- FIG. 12A shows a spring plunger 38 of diameter d1 with finger 34 of diameter d3. This finger plunger 34 allows for example a deflection w2 from 0 to 0.5 mm.
