Patent Issued for Method and Device for Placing Thin Material Layers onto a Relief Mould

摘要

From the background information supplied by the inventors, news correspondents obtained the following quote: "Normally, composite materials are produced in that thin deformable material layers, such as for example woven materials, interlaid scrims, prepregs, papers, veneers, metal sheets, foils, nonwoven fabrics, and mats, or other sheet-like flexible material layers that in the context of the present invention are collectively referred to as a 'material layer', are removed from a flat surface, such as for example a table, and are placed one on top of the other in a mould tool that comprises a base surface that is curved in one or two directions. In these known production processes of composite materials, up to now the individual material layers have been manually picked up and placed in the mould tool. While there have been experiments to automate the placing of material layers in the mould tool, these experiments have, however, so far exclusively resulted in very expensive robot-gripper kinematics that are associated with very considerable technical implementation expenditure and enormous costs without returning anywhere near satisfactory results.
