It is thus the object of this invention a pallet block (3) comprising a core (1) of wood particleboard and an outer layer (2) of wood fibreboard, the outer layer (2) at least partially coating the core (1), and the assembly formed by the core (1) plus the outer layer (2) being obtained by subjecting it to pressure. This enables a pallet block (3) to be obtained allowing high weights to be supported, without the whole block (3) being comprised of wood fibreboard, and with characteristics of robustness, thus avoiding the need for gluing between the elements. ## Claims ### Claim 1 A pallet block (3) comprising a core (1) of wood particleboard and an outer layer (2) of wood fibreboard, the outer layer (2) at least partially coating the core (1), and wherein the core (1) and the outer layer (2) are subjected to pressure to form an unitary structure assembly formed as one, in which the outer layer (2) has a tubular configuration and the core (1) is formed inside the outer layer (2), such that the pallet block is dimensioned for placement at individual and spaced-apart locations along a length of a pallet. ### Claim 2 (depends on 1) A block (3) according to claim 1, wherein the outer layer (2) has a rectangular tube configuration and wherein the core (1) consists of a parallelepiped or the outer layer (2) has a circular tube configuration and the core (1) consists of a cylinder. ### Claim 3 (depends on 1) A block (3) according to claim 1, wherein edges between two external faces of the outer layer (2) are cut. ### Claim 4 (depends on 1) A block (3) according to claim 1, wherein the wood particleboard of the core (1) and the wood fibreboard of the outer layer (2) are bonded with glue. ### Claim 5 (depends on 4) A block (3) according to claim 4, wherein the gluing of the wood particleboard of the core (1) with the wood fibreboard of the outer layer (2) is made by using thermosetting glue. ### Claim 6 (depends on 4) A block (3) according to claim 4, wherein the gluing of the wood particleboard of the core (1) and the wood fibreboard of the outer layer (2) is carried out by curing the glue under pressure. ### Claim 7 (depends on 1) A block (3) according to claim 1, wherein an external surface of the outer layer (2) is pigmented. ### Claim 8 (depends on 1) A process for obtaining a pallet block (3) according to claim 1 comprising the following steps: bonding of wood particleboard and wood fibreboard with glue; inserting the wood particleboard into an inner area of a prismatic or cylindrical mould and the wood fibreboard into an entire side layer surrounding the inner area of the mould; and closing the mould and subjecting the interior thereof to a pressure in the range of 35-45 kgf/cm2 so that the bonding glue is cured. ### Claim 9 (depends on 8) A process according to claim 8, wherein after the subjection to pressure, demoulding is carried out with subsequent cooling of the block (3) obtained from the cure. ### Claim 10 (depends on 9) A process according to claim 9, wherein, after the demoulding and cooling, burrs and/or debris of excess material from the walls to the mould are cleaned. ### Claim 11 (depends on 8) A process according to claim 8, wherein the step of bonding the wood fibreboard comprises the addition of a pigment. ### Claim 12 (depends on 8) A process for obtaining a pallet comprising the step of attaching at least one platform to at least four blocks (3) obtained according to the process provided for in claim 8. ### Claim 13 (depends on 12) A process according to claim 12, wherein the step of attaching includes attaching in the periphery of one same face each of the two platforms to the blocks, which are thus arranged between the two platforms. ### Claim 14 A pallet comprising at least one platform and at least four blocks (3), each block (3) comprising a core (1) of wood particleboard and an outer layer (2) of wood fibreboard, the outer layer (2) at least partially coating the core (1), wherein the core (1) and the outer layer (2) are subjected to pressure to form an unitary structure assembly formed as one, in which the outer layer (2) has a tubular configuration and the core (1) is formed inside the outer layer (2), such that the pallet block is dimensioned for placement at individual and spaced-apart locations along a length of a pallet, the blocks (3) being attached in a periphery of one same face of the platform. ### Claim 15 (depends on 14) A pallet according to claim 14, further comprising studs, which are arranged so that each one of the blocks (3) is attached to the platform, each of the studs perforating the whole outer layer (2) and part of the core (1) of each block. ### Claim 16 (depends on 14) A pallet according to claim 14, further comprising two platforms between which the blocks are arranged, the blocks (3) being attached in the periphery of one same face of each of the platforms.
