Assembly, plant and method for making a preformed shell

An assembly for preforming a reinforced fabric sheet, said reinforced fabric sheet being intended to receive at least one deforming action for making a preformed shell, comprising:

• at least one frame;
• a plurality of gripping devices suitable for gripping the reinforced fabric sheet, said plurality of gripping devices being directly or indirectly associated with said at least one frame;
• wherein:
• each gripping device of said plurality of gripping devices being suitable for gripping an edge portion of the reinforced fabric sheet;
• said assembly further comprises a moving system comprising a plurality of first moving devices;
• wherein
• the movement of each first moving device is independent of the other first moving devices;
• each gripping device of said plurality of gripping devices being associated with a first moving device;
• said first moving device being suitable for moving each gripping device of said plurality of gripping devices independently of the others so that when said reinforced fabric sheet is gripped by said plurality of gripping devices, each gripping device may move to guide localized deformations of the reinforced fabric sheet which arise during the deforming action of the reinforced fabric sheet.
