Abstract: A process and device are disclosed for processing fibre pieces. The fibre pieces (24) are introduced into a gas-solid mixture by a transport section (11) of a heating device (14). In the heating device (14), the free ends of the fibre pieces (24) are rounded and/or thickened. After leaving the heating device, the processed fibres (25) flow into a conveyor section and then into a separator device (18), in which the gas-solid mixture is separated. The fibre pieces produced according to the disclosed process considerably improve the mechanical quality characteristics and properties of fibre reinforced composite materials. The disclosed device allows the disclosed process to be implemented in a particularly economical manner.

Abstract: The invention relates to a device for injection moulding of plastic parts with undercuttings, which comprises an injection moulding tool having at least two parts and the separated moulding elements forming the undercuttings. Said moulding elements, which are shaped as loose cores of a subliming substance, e.g. solid CO2, can be positioned in solid aggregate state on the inlets of the injection moulding tools. Once the injection has been completed the injection moulding tools have been opened, they are converted to the gaseous aggregate state.
