The arti.cle 14 is clamped between the boards 169 17 of a moulding machinery ,shown in FIGURES from 4 to 6~
with the confrontingly placed 'inner surfaces of the sheets 11 spread with an adhesive. Between the sheets 11 it is possible to slip injection nozz,l.es 18, one for each side o~' the panel ( FIGURES 3 and 6). Each nozzle 18 can slide towards and away in the directions shown by the arrows and has a front 19 ( FIGURE 5 ) the langth of which is about equal - 10 to that of the respective side of the panel ,., As shown in FIGURE 4, the nozzles 18 are first in~
'` troduced along a certain distance between the sheets ll .... .
so as to define a firs-t enclosure having a volume equal to i that o the core 12 a said enclosure being filled with a ~ first expanded material. If the material which is used ~i - is~ for example~ polystyrene, it can be advaritageously introduced by nozzles 20 formed through the nozzles 18.
The material is then expanded by introducing into the en-~ closure a pressurized hot fluid. such as steam through ",~ 20 injectvrs 21 in the nozzles. The expanded material is firmly united to the internal surfaces of the sheets 11 which had previously been spread with an adhesive as afore-said. Thus the core 12 of the panel has been provided.

This space is filled, st,ill ~ through the injectors 207 with a second expanded material ',, ''. having a density heavier than that oE the ~irst material.
'.~' 30 I the material wh.ich is used is polystyrene again~ it is expanded as in the previous stage by introducing a hot fluid , through 21.

The arti.cle 14 is clamped between the boards 169 17 of a moulding machinery ,shown in FIGURES from 4 to 6~
with the confrontingly placed 'inner surfaces of the sheets 11 spread with an adhesive. Between the sheets 11 it is possible to slip injection nozz,l.es 18, one for each side o~' the panel ( FIGURES 3 and 6). Each nozzle 18 can slide towards and away in the directions shown by the arrows and has a front 19 ( FIGURE 5 ) the langth of which is about equal - 10 to that of the respective side of the panel ,., As shown in FIGURE 4, the nozzles 18 are first in~
'` troduced along a certain distance between the sheets ll .... .
so as to define a firs-t enclosure having a volume equal to i that o the core 12 a said enclosure being filled with a ~ first expanded material. If the material which is used ~i - is~ for example~ polystyrene, it can be advaritageously introduced by nozzles 20 formed through the nozzles 18.
The material is then expanded by introducing into the en-~ closure a pressurized hot fluid. such as steam through ",~ 20 injectvrs 21 in the nozzles.

'.~' 30 I the material wh.ich is used is polystyrene again~ it is expanded as in the previous stage by introducing a hot fluid , through 21.
I Thus the Erame 13 has been formed around ~he core 12 ,) and a sandwi.ched panel structure has been formed 10, as ', 35 shown. in FIGU~E 1.
3--The panel 10 is removed from the moulding machinery and sent to further processing, which can be o a nature which differs according to the :intended final use for the article~ but after ha~ing stak-lized the latter: s-tabili-~ation can take place both in-the moulds or in a specially ptovided ~ontrolled environment.
The panel according to the invention has proven parti-cularly advantageous for the manufacture of doors by virtue of its differential internal structure which is composed by the core 12 and the frame 13, made of a lighter and a dens~r material~ respectively~
The frame 13 of a denser rnaterial~ in addition to l impress an adequate stiffness to the structure, can also ; ~- readily and quickly machined to the shape corresponding to ,,! 15 a conventional door ledge~ to be coated subsequently with ' an appropriate material~ such as a veneer.
1 In this connection it can be noted that the nozzles }l 18 can be shaped with projecticns so as to define~ in the , side of the frame 13, spaces in which plugs of a hard material~ such as wood~ are insf3rted firmlyg so as to be adapted to receive the hinges and the locks for the door.
