Definitions
- This invention relates to an installation and a process for making panels.
- this invention relates to an installation and a process for making panels used for the construction of a building or the like.
- Panels used for building construction are well known. These prior art panels comprise a panel body, made in particular of expanded polystyrene associated with metal meshing or reinforcement. Production of these prior art panels involves making panel reinforcement mesh in sheets of predetermined length corresponding to the length of the polystyrene panel. This is done in a dedicated machine and the expanded polystyrene panel body and the sheets of reinforcement mesh are then assembled in a separate machine.
- a sheet of reinforcement mesh is first placed on the machine work table, the expanded polystyrene panel body is laid on the sheet and another reinforcement sheet of mesh then laid over the expanded polystyrene panel body.
- making panels of desired length and dimensions involves making metal meshing of the desired length on a specific machine and associating it with the corresponding polystyrene body of the desired length in a different machine.
- the entire process is thus lengthy and problematic for the personnel involved.
- the length of the panel is determined by the length of the components used to make it and it is not possible to change it during processing.
- the result is a system that is limited in flexibility and unable to adapt to changed processing requirements.
- This invention therefore proposes a new solution as an alternative to the solutions known up to now and, more specifically, proposes to overcome one or more of the above mentioned drawbacks and/or problems and/or to meet one or more of the above mentioned requirements.
- an installation for making panels in particular panels used for the construction of a building; characterized in that it comprises means adapted for making a longitudinal body of material for panels; and in that it comprises means for making from the body of panel material panels whose length is selectively predetermined.

- the mounting beam 143 is mounted on corresponding side portal frames, each having uprights 144, 144 spaced longitudinally far enough from each other to allow the panel A to pass between them, that is to say to allow the pile A' of panels to fit between them so that they can be easily picked up by a forklift truck, for example.
- the uprights 144, 144 mount a corresponding crossbar 145 which supports one end of the crossbeam 143 substantially half way along the crossbar 145 itself.
- the means for unloading the panel from the line might comprise, instead of a single crossbeam 143, a pair of crossbeams which are smaller in cross section and lighter in weight and which might be made longitudinally movable on the upper crossbar 145 of the respective side portal frames in such a way as to also allow longitudinal movement of the pickup means.
- the installation described above implements a process for making panels A used for the construction of a building; the process advantageously comprising making a longitudinal body B of panel material and making from the body B of panel material panels A whose length L is selectively predetermined.
- the body B of panel material comprises a main portion C of material constituting the main panel element Al, made preferably of insulating or lightening material, especially expanded plastic material, preferably expanded polystyrene, associated with at least one strip, or part, and more specifically first and second parts, or strips D2, D3 constituting reinforcement means A2, A3 of the panel A.
- expanded plastic material preferably expanded polystyrene
- the process more specifically comprises making a longitudinal body B of panel material and cutting the body B of material into panels A.
- the process involves cutting the main portion C of panel material and the reinforcement means D2, D3.
- the length L of the panel A may be equal to or different from the length LO of the component block but is normally different from the length LO of the respective component block Cl.
