ABSTRACT:
A thread feeding buffer for feeding a fibre thread from a magazine roll to a feed apparatus at a robot arm which is freely movable in the room. The thread feeding buffer including a thread brake and at least one movable thread guide on which a thrust force is acting. The thread is running from the magazine roll via a brake through the thread guide 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 and the feed apparatus, which buffer is variable in length. At least one guide rod for guiding the movable thread guide is 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 the movable thread guide.
