<p>A yarn tuft forming unit (1) comprises a yarn selector wheel (20) with provision for holding a number of different yarns (23) arranged generally radially, means (21) to drive the selector wheel (20) into a selected one of a number of angularly discrete positions to bring a selected yarn (23) to a loading position, a puller (29) for engaging the selected yarn (23) at the loading position and pulling a predetermined length of the selected yarn (23) from the selector wheel (20), and a cutting mechanism (28) to cut the selected yarn (23) to form a tuft (7) of predetermined length. Such a tuft forming unit (1) is preferably used to supply yarn tufts (7) to an Axminster carpet weaving loom. Typically a number are provided across the width of the loom and together they traverse the whole width of the loom to provide yarn tufts (7) for a complete row of carpet. Each tuft forming unit (1) provides tufts for a significant number of weaving points and thus a considerable reduction in the size of the creel can be obtained. <IMAGE></p> |
