<p>A nip (18) for a yarn (11) is formed between an end of a tubular member (12) and a flattened loop section (16) of an elongate tensioning member (15). The member (12) is slidably mounted on an outlet end of a yarn tube (10) and is biased by gravity towards the section (16), thereby to exert tension on the yarn (11). The tensioning member (15) includes a further loop section (19) which acts as a guide for the yarn.</p> |
