  • the cylinder 224 therefore has the function of return the pusher 217 to its initial position. Its stem 223 is normally in the extended position, waiting for receive the pusher 217.
  • each of the chains being provided with a pushing finger 216 cooperating each with a jack 224, and this, in a synchronized way.
  • Electronic and pneumatic means (or possibly hydraulic) of the production line control the operation of the production apparatus footprints and slats introduction device under the preform constituted by means 20 to 22 and 24 to 39 described above, so that once the pusher 117 returned to its initial position and the rod 223 of the cylinder 224 again out, a new slat 23 can be slipped on the inclined plane 33.
  • the actuation of the cylinder 224 is determined by detection for example by means of of a photoelectric sensor, the passage of a pin or finger attached to a suitable place on the chain 206, by example in the same way as the push finger 216, this ergot playing the role of flag, that is to say that when detected by the photoelectric sensor arranged at a suitable place on the production line or the apparatus, the electronic means control the return of the rod 223 of the cylinder 224 in the body of the cylinder, this return entailing, as explained above, the return of the pusher 217 to its initial position. of the limit sensors of cylinder 224, can then, once the rod 223 returned, cause a new actuation of the jack 224 to pull out its rod 223, which drops the pusher 217 to its original position.
  • the frame 205 of the apparatus according to the invention can, as shown in Figure 16, to be trays 214 and 215. It follows that the apparatus according to the invention can be used in place of a forming flat or a master roll that is used classically.
  • the forming strip 1 is the one in the lead.
  • a classic conveyor belt generally comprises 2 or 3 or even 4 forming strips. These, as indicated above, include "tap" to form the longitudinal thinned edges.
  • the other elements remain identical (prints 12 or 12bis, as the case may be), except that the latte is introduced at a point on the line at which hydration of the hydraulic binder has begun (see below in the section on the third variant).
  • Others constituent elements are shifted accordingly (for example the straightener 4a is shifted at or after the first roll driving the second forming strip; in this case the straightener takes the form of a roller having a peripheral speed substantially identical to that conveyor belt 7).
  • this variant is represented in FIG. this one, the impression 12 made, notably by the device according to the invention is "pushed back" towards the high by a device 300 located under the preform.
  • This system is in fact the opposite of the one No. 2,991,824.
  • the system for pushing the print is located downstream of the forming device.
  • this inversion device lies between the bands 1 and 2 (but it is also possible to place it between bands 2 and 3, if applicable). These measures is placed at a point in the band at which hydration of the hydraulic binder has begun.
  • this device is located at one place corresponding to 5% to 30% of the hydration, and / or place between 40 and 110m of the length of the band 7 (for example for a line with a speed of about 70 m / min).
  • This device 300 is placed between the strips 1 and 2, referenced 301 and 302, respectively. These bands are driven by rollers 303 and 304, respectively.
  • the device 300 comprises on the one hand a device for secondary forming 300a. This includes, on a chassis (not shown), a 305 band, rotating to a linear velocity equal to the speed of the bands 301 and 302. This avoids slipping of the facing. Sure this band 305 is fixed one or more batten (s) of forming 306 coupled to this band 305. In what follows the description is given with reference to only one latte but according to the dimensions of the devices, wanted plates, etc., we can use several slats.
  • This strip is mounted on rollers 307 and 308, at least one of which is preferably motorized.
  • a plate 309 slippery plane for example marble, is disposed between the preform and the strip 305 so that these are in contact on a flat surface.
  • a "counter device" 300c This includes, on a chassis (not shown), a band 310, rotating at a linear speed equal to the speed of the strips 301 and 302, this band 310 being mounted on rollers 311 and 312, at least one of which is preferably motorized.
  • a plate 313 sliding plane for example marble, is arranged opposite between the preform and the 310 band similarly to the arrangement of the plate 309 and the strip 305.
  • the forming slat 306 comes opposite of the upper imprint 12 in the preform. This when lath 306 passes at the same time as the preform between the two plates 309 and 313, the impression is "hunted” on the other side of the preform. We then gets a preform arriving on the tape forming 302 which has a recess corresponding to a transverse thinned edge (on the same side of the plate as the longitudinal thinned edges).
  • the preform passes between the two strips 305 and 310 which are preferably motorized at the speed of displacement of the preform.
  • the preform is therefore in contact only with moving elements, so that the relative movement preform / bands is zero. There is no so no friction.
  • the dimensions of the device are of the order of a few meters (typically there is contact during 5 to 10m), generally sufficient to ensure the secondary forming.
  • Adjustment means not shown, of the pressure exerted by this "counter-device” may be present. These may include cylinders or counterweight likely to exert an adjustable pressure overall.
  • Synchronization means are preferably provided so that the forming slat 306 secondary is substantially in front of the footprint 12.
  • a cutting system consisting of a wheel can be used placed on the top of the preform and driven in rotation by the displacement of the latter. Wheel is graduated and coupled to a counter that operates the desired devices. You can also use a system comprising a step of marking the facing of the preform (eg a dot), and the detection of this mark and actuate the devices accordingly.
  • the device 300 further comprises a device for calibration 300c.
  • the lath 306 is retracted when the strip 305 rotates around roll 308; the preform then enters the calibration device 300C.
  • This one includes, on a chassis (not shown), a band 314, rotating at a linear speed equal to the speed bands 301 and 302, this band 314 being mounted on rollers 315 and 316, at least one of which is motorized preference.
  • a plate 317 sliding plane, by marble example, is arranged between the preform and the strip 314 in a manner similar to the arrangement of the plate 309 and the band 305.
  • a straightener of the same type as that described for the second variant may possibly be provided.
  • This variant corresponds to the case where the device of Figures 19 or 20 is reversed, namely that the slat 306 is not arranged to repel the imprint and form the transverse thinned edges of the same side as the longitudinal thinned edges, but at contrary to "confirm" the impression and the reservation of form.
  • the application of the forming slat at a stage at which the binder hydraulic started hydration allows to have as above a consistency of the ideal preform to moment of secondary forming.
  • the length of the slat 306 is approximately equal to the width of the preform.
  • the slat used in the invention, and especially the latte 306, can have a profile in parallelepiped, but also in the form of a triangle, in general isosceles, whose base is parallel to the carpet 7.
  • the third and sixth variants have in common that the footprint 12, respectively 12bis, is "repulsed” by a device under the preform, respectively above the preform.
  • the impression is "repulsed” in its entirety, that is to say that the facing paper is substantially plane a once the impression has been "pushed back". It is possible predict that the action of consisting of pushing back impression is only partial, namely that there remains a depression on each side of the plate, one being more pronounced than the other.
  • the device 300 so that the ratio of depths of depressions on each side is between 1 and 10, preferably between 2 and 5.
  • the depth of depression "pushed back" side can be 4mm while the depression on the side original can be 1.5mm.
  • the subject of the invention is a method of constructing the second work, using the plates with four thinned edges, two of which are thinned on one face while the other two are on the other face of the plate.
  • Such plates can be obtained by the first variant (with the imprint 12) fourth and fifth variants, as well as the third and sixth modified variants.
  • Such a plate is shown schematically in Figure 21. It shows that the thinned ones are arranged on each face of the plate, in the opposite way (edge thinning is on the siding side cream (10) while tip thinned are on the other side, "gray" side (25bis).
  • the dimensions of thinned 25bis are usually of the same order of magnitude than those of thinned 25 (which corresponds to the latte dimensions in the case of the fourth or fifth variant or elongate means 110 comprising the son 111 in the case of the first variant by example).
  • the thinned 25bis may therefore have a depth between 0.5 and 4 mm, preferably between 1.5 and 4 mm.
  • the width can be from the thinned between 2 and 15cm, preferably between 5 and 10cm. Longitudinal thinning have the standard dimensions in art, as given by the "tapes" so classic.
  • step b) the transverse thinned edges, which are on the side of the plate not visible to the installer, are "returned” or “reassembled” under the effect of the fixing by screws, nails or other, because this area of the plate is tight on the frame. In doing so, they then release a thinned on the same side of the plate as the longitudinal thinned edges (or thinned edges). We then gets thinner edges at each level of junction of the plates.
