A thread feeding buffer for feeding a fibre thread (15) from a magazine roll (14) to a feed apparatus at a robot arm which is freely movable in the room. The thread feeding buffer comprises thread brake means (16, 19, 20) and at least one movable thread guide (17), on which a thrust force is acting. The thread is running from the magazine roll (14), via the brake means (16, 19, 20), through the thread guide (17) and further on towards the feed apparatus in such a way, that the thrust force acts for creation of a thread buffer between the brake means and the feed apparatus, which buffer is variable in length. At least one guide rod for guiding the movable thread guide is provided with means arranged to cause a braking effect on downward movement of the movable thread guide for preventing entanglement of the thread fed through the movable thread guide following a rapid fall of said movable thread guide.
L'invention concerne un tampon d'alimentation de fil servant à alimenter un fil (15) de fibre d'un rouleau (14) de magasin à un appareil d'alimentation situé sur un bras de robot pouvant être déplacé librement dans une pièce. Le tampon d'alimentation de fil comporte un moyen (16, 19, 20) de freinage de fil et au moins un guide-fil (17) mobile sur lequel agit une poussée. Le fil provient du rouleau (14) de magasin, passe par le moyen (16, 19, 20) de freinage, à travers le guide-fil (17), et continue en direction de l'appareil d'alimentation de telle sorte que la poussée permet de produire un tampon de fil entre le moyen de freinage et l'appareil d'alimentation, ce tampon étant de longueur variable. Au moins une tige de guidage servant à guider le guide-fil mobile est équipée d'un dispositif conçu pour produire un effet de freinage sur le mouvement descendant du guide-fil mobile, afin de prévenir un embrouillement du fil passant à travers le guide-fil mobile, consécutif à une chute rapide dudit guide-fil mobile.
