  "Improvements to pallets, '.



   This invention relates to improvements to pallets and more particularly to an improved pallet and to the method of manufacturing the latter, this pallet having a particular use in the manufacture of bricks.



   In the manufacture of bricks, it is customary to mount the formed bricks, still wet, on a pallet, usually a pair of wooden spars parallel to each other, so that the brick is posed crosswise two wooden pallets. Several bricks placed on this pallet are then placed in a drying chamber, in which the bricks dry for a few hours at a tempe-

 rature reaching 120 ° C. After drying, the bricks are removed from the drying chamber and placed on pieces of steel or fired clay and fired in a high temperature oven.



     It will be appreciated that wood is not a particularly suitable material for such a pallet, since the wood gets wet on contact with the damp bricks placed on it and then dries in the drying chamber. The wood is therefore constantly wet and dried and so it tends to warp, rot and deteriorate so that the life of these pallets made only of wood is relatively short.



   An object of the present invention is to provide an improved pallet which has a substantially longer life than a wooden pallet and also provides an improved process for manufacturing the pallet.



   The invention provides a pallet comprising a wood core, a canvas covering this core and a synthetic resin coating applied to this blanket to bond the core and the blanket together and provide a protective surface for the pallet.
It is convenient to cover conventional firm wood pallets with a textile cover which can advantageously have the shape of a sock so as to be able to introduce the wood pallet in this envelope and then to close the ends by which one has. introduced the pallet.



   The wooden pallet is covered, preferably by immersion spraying or painting the plaster, for example a synthetic resin in liquid form, so as to impregnate the textile cover and thus the resin penetrates into the openings of the textile material and sticks strongly the cover to the pallet of. wood and also provides a protective surface for the pallet itself. The synthetic resin is then allowed to harden.

 tick.

   A chemically curing synthetic resin from the group of epoxy resins is advantageously used, but other synthetic resins such as those which cure by evaporation or by heat or the like can be used.
The present invention also provides a method of making a pallet which comprises covering a wooden core with a canvas, applying a liquid synthetic resin to the canvas and allowing the resin to harden to give a protective surface to the canvas. -palette.



   In a specific example, a piece of strip-shaped wood having the dimensions and thickness required for a pallet is first treated with a "chemidus lamellon" resin - code N 41 TAP (trade name). This resin serves to form a resinous surface on the piece of wood to prevent liquids or the like from seeping out of the piece of wood and causing the knots to burst. The resin is allowed to harden and after hardening, the resin-treated piece of wood is introduced into the tubular textile casing which is advantageously knitted and which is closed at one end.



   The piece of wood stretches the textile so that this material is stretched and fits well on the treated piece of wood. The end of the tubular casing through which the piece of wood has been introduced is folded back on itself and the covered piece of wood is then treated with a resin, such as for example that which was mentioned above.



    A coloring material may be added to this resin, such as, for example, coloring paste No. 4789 manufactured by "Rylands Limited" in the United Kingdom. The application of the resin to the roofing is such that it is impregnated with resin and it sticks to the piece of wood already treated with resin.



   After this treatment, the part is allowed to dry for about seven days and thus the resin - can harden at a temperature -

 <Desc / Clms Page number 4>

 temperature of about 18 C. The temperature should preferably not be lower than 18 C and the setting time can be reduced by raising the temperature to 29 C without exceeding it.



   After the cover resin has hardened, the pallet is complete and can be used in the usual way. The resin is waterproof and prevents water penetration of wet bricks and is insensitive to the constant wetting and drying to which ordinary wooden pallets used in brick making are regularly subjected.



   In order to make this easier to understand

 invention, it will be reiterated .. 'I.U de, .t, ri attached in which: Figure 1 is a perspective view of a pallet completed according to the present invention; FIG. 2 is a cutaway perspective view showing the construction of the pallet according to the present invention; Figure 3 is a cross section of a pallet according to the present invention.



   The pallet 1 is formed by a wooden core 3 surrounded by a tubular casing 2 impregnated with subsequently hardened resin forming the outer casing 1 (figure 2.),
The present invention provides a useful method of manufacturing an improved pallet for use in the manufacture of bricks and the like.



   It should also be noted that usually pallets are made with the best quality straight-grained Oregon pine in order to withstand heat, humidity and wear, but this wood is relatively expensive.



   On the other hand, since the wooden core, according to the invention, is provided with a coating which protects it against heat, humidity and wear, the core can be made with a much cheaper wood, for example. example of white wood.

   The resin application process by spray gun can be used with a gun equipped with a wire nozzle.



   The method of applying the resin by immersion has the advantage that it can be carried out automatically, saving labor.



   The resin used can be any suitable high temperature resistant resin.
