Description

L'objet de l'invention consiste en un procédé_pour la fabri-

  
 <EMI ID=2.1> 

  
les tuiles, aussi bien celles en argile que celles on béton,

  
étaient fabriquées isolément dans des formes particulières, ce qui

  
rendait naturellement très difficile la fabrication en masse.

  
'suivant 1*'invention, des tuiles, avantageusement en béton,

  
seront maintenant fabriquées en étendant une coucha; de; béton sur

  
 <EMI ID=3.1> 

  
rieure, au moyen d'organes racloirs que l'on peut passer sur

  
celle-ci dans le sens longitudinal de la tuile. En conséquence, ne

  
se prêtent à ce procédé que les tuiles présentant partout le même

  
profil sur leur face supérieure, tandis que la face inférieure de

on renonce à un profil particulier de la face inférieure de

Après cela, il suffit seulement de prévoir, dans-le lit inférieur, les cavités pour les bossages d'accrochage, tant que la masse

Les :.:rangées individuelles de tuiles ainsi fabriquées sont séparées les unes des autres par des couteaux que l'on fait passer entre celles-ci, tandis que la division transversale, a la longueur des tuiles, est exécutée par des couteaux transversaux appropriés.

  
La mise en oeuvre de ce procédé n'exige donc aucun moule spécial en bois ou en fer, ce qui constitue une grande économie

  
de matériel. Le procédé peut être exécuté aussi bien dans des  espaces fermés qu'à l'air libre, sur tout support solide et plan, du moment que, pendant les premières heures après la compression, le béton est protégé contre la lumière solaire et la pluie. Com-

   <EMI ID = 1.1>

  
The object of the invention is a process for the manufacture

  
 <EMI ID = 2.1>

  
tiles, both clay and concrete,

  
were made in isolation in particular shapes, which

  
naturally made mass production very difficult.

  
'according to the invention, tiles, advantageously of concrete,

  
will now be made by extending a coucha; of; concrete on

  
 <EMI ID = 3.1>

  
upper, by means of scrapers which can be passed over

  
this in the longitudinal direction of the tile. Consequently, do not

  
lend themselves to this process as the tiles presenting everywhere the same

  
profile on their upper face, while the underside of

  
 <EMI ID = 4.1>

  
plane .. Four as much as ,. in the choice of the shape of the tile,

  
a particular profile of the underside of the

  
 <EMI ID = 5.1>

  
After that, it suffices only to provide, in the lower bed, the cavities for the hooking bosses, as long as the mass

  
 <EMI ID = 6.1>

  
The:.: Individual rows of tiles thus produced are separated from each other by knives which are passed between them, while the transverse division, to the length of the tiles, is carried out by suitable transverse knives.

  
The implementation of this process therefore does not require any special mold in wood or iron, which constitutes a great saving.

  
of material. The process can be carried out both in closed spaces and in the open, on any solid and level support, as long as, during the first hours after compression, the concrete is protected against sunlight and rain. Com-

large concrete tank, which extends over the entire width of the device and has a dumping hopper at its lower part, through which the concrete falls onto the work surface. The poured concrete without settling is scraped to the height

corresponding to the profile of the tiles, while we then drive, through the concrete, parallel knives whose spacing corresponds to the individual width of the strips or rows

that the strips of: finished tiles can now remain in clamp and take without further support.

  
the actual compression of the concrete can take place in any way, but for this purpose advantageously used} profiled compression lacquers, provided for the rolling apparatus, which are folded upwards at their front part, like runners sled, to slide over concrete like a water train.

  
.four the compression of the concrete is used, moreover, advantageously of vibrators which act on the compression plates, either directly or through the intervention of appropriate intermediate connections. Such vibrators have a high frequency of vi- <EMI ID = 10.1> <EMI ID = 11.1>
