Abstract
An assembly for preforming a reinforced fabric sheet may have at least one frame and a plurality of gripping devices. Each gripping device of the plurality of gripping devices may be suitable for gripping an edge portion of the reinforced fabric sheet. The assembly may have a moving system with a plurality of first moving devices. The movement of each first moving device may be independent of the other first moving devices. Each gripping device of the plurality of gripping devices may be associated with a first moving device. The first moving device may be suitable for moving each gripping device of the plurality of gripping devices independently of the others.
Claims9
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 one of said first moving devices;
- each of said first moving devices 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,
- a plurality of supports directly or indirectly associated with said frame, each support of said plurality of supports also being directly or indirectly associated with at least one gripping device so as to support said at least one gripping device;
- and
- wherein each support is associated with a respective gripping device and a respective first moving device;
- and
- wherein said first moving device is fastened to said support and each gripping device further comprises a carriage associated with said support and suitable for translating with respect to said support when moved by said first moving device;
- and
- wherein at least one support comprises at least one support joint;
- and
- wherein said support is associated with said frame via said support joint which guides the rotation of the support with respect to the frame.
