A device for feeding out reinforcement fibres at production of thermosetting plastic products, which device includes at least one magazine spool for a fibre thread, and guiding means for guiding the fibre thread to a fibre feedout head. The feedout head is provided with feed means for feeding the fibre thread from the magazine spool coil via the guiding means, and cutting means, which enables cutting off the fibre thread. The feed means of the feedout head means include on one hand driven feed rollers, which form at least one nip for the fibre thread and on the other hand fibre ejecting means. The cutting means are individually driven and placed between the feed rollers and the fibre ejecting means.
Dispositif servant à effectuer l'alimentation en fibres de renforcement pendant la fabrication de produits plastiques thermodurcissables et comprenant au moins une bobine d'alimentation d'un fil en fibres (15) et des moyens de guidage (17, 18, 19) servant à guider ledit fil vers une tête d'alimentation en fibres (13). La tête d'alimentation est pourvue de moyens d'alimentation (21, 22, 31, 32) servant à conduire le fil en fibres depuis la bobine d'alimentation par l'intermédiaire des moyens de guidage et de moyens coupants (26, 27a, 27) permettant de sectionner le fil. Les moyens d'alimentation de la tête d'alimentation (13) comprennent, d'une part, des rouleaux d'alimentation entraînés (21, 22) formant au moins un point de contact pour le fil (15) et, d'autre part, des moyens d'éjection des fibres (31, 32). Les moyens coupants (26, 26a, 27) sont entraînés individuellement et placés entre les rouleaux d'alimentation (21, 22) et les moyens d'éjection des fibres (31, 32).
