摘要： The invention relates to a method and a device for producing a three-dimensional preform (19) from a fibre fabric (1) as part of production of fibre-reinforced formed components, comprising a draping device (3) and a transport device (21) for the fibre fabric (1), wherein said draping device (3) at least comprises a draping form (18) for a fibre fabric (3) and means, movable in relation to the draping form (18), for reshaping the fibre fabric (3) on the basis of the contour of the draping form (18). The problem addressed by the invention is that of ensuring swift yet high-quality reshaping, particularly of large-area and/or complex geometries of a preform. To solve the method problem, the invention states that the transport device (21) successively releases the fibre fabric (1) in the direction of the draping form (18) and the released regions of the fibre fabric (1) are fixed and/or draped on the draping form by means of a fixing stamp (4) and/or a draping stamp (5).

摘要： A method and apparatus for adaptively controlling a hydraulic press comprising a hydraulic drive unit for lifting and lowering a press ram. A piston chamber of the drive unit can be connected to a hydraulic accumulator formed by at least two groups of storage bottles, the connection established by hydraulic pipes that allows an expandable volume, stored in the storage bottles to supply the energy required for the press to perform a working stroke. Different filling pressures can be established in the storage bottles. A hydraulic accumulator can be adjusted to three operating modes, allowing a press controller to automatically analyze utilization and accordingly block individual groups or compartments of storage bottles, transfer the gas between storage bottles during a charging process at the end of the cycle, or adjust individual groups of storage bottles to different pressure levels. Advantageously, these three scenarios entail no waiting or transfer time.

摘要： A tape-laying apparatus includes a material feeder configured to feed tapes, and a laying device configured for picking up and placing tapes onto a laying table. The laying device includes a transporter and a vacuum. The vacuum is connected to the transporter such that at least one tape is configured to be held on the transporter by a negative pressure generated by the vacuum. The transporter includes at least two endless transport belts, which circulate around deflection rollers. The transport belts run parallel to one another in a same transport plane.

摘要： A method for consolidating a fiber composite structure with at least one thermoplastic and/or thermoelastic polymer includes arranging the structure between a plate-shaped base and a plate-shaped cover in a loading/unloading station of a conveying device. The cover is sealed with respect to the base by a seal to be displaceable in relation to the base. The method includes generating negative pressure in the interstice between the base and the cover so the ambient pressure pushes the cover against the base, the structure being clamped between the cover and the base; heating the composite structure by electromagnetic radiation preferably at least into the range of the melting temperature of the at least one polymer in a heating station, cooling the composite structure in a cooling station of the conveying device; and removing the consolidated structure from the base or removing the base onto which the structure has been placed.
