A carpet weaving loom including at least one tuft forming unit (1) for forming sequentially yarn tufts (7) of a number of different colours, means to receive and hold at yarn tuft holding sites (8) yarn tufts supplied sequentially by the tuft forming unit (1), and transfer means (10) to transfer all of the tufts (7) held by the yarn tuft holding sites (8) simultaneously to their corresponding weaving points. The or each tuft forming unit supplies yarn tufts (7) to at least twenty yarn tuft holding sites (8) between successive operations of the transfer means (10). When only a single tuft forming unit (1) is provided it preferably supplies tufts to at least one hundred and sixty tuft holding sites (8). When a plurality of tuft forming units (1) are provided each preferably supplies tufts to between twenty and one hundred and twenty tuft holding sites (8). This configuration leads to a considerable reduction in the size of creel with consequent reduction in waste and time taken to thread-up such a loom.
A carpet weaving loom including at least one tuft forming unit (1) for forming sequentially yarn tufts (7) of a number of different colours, means to receive and hold at yarn tuft holding sites (8, 73) yarn tufts (7) supplied sequentially by the tuft forming unit (1), and transfer means (10, 72) to transfer all of the tufts (7) held by the yarn tuft holding sites (8, 73) simultaneously to their corresponding weaving points, characterized in that the or each tuft forming unit (1) supplies yarn tufts to at least twenty yarn tuft holding sites (8, 73) between successive operations of the transfer means (10, 72).
A carpet weaving loom according to any one of the preceding claims, in which the or each tuft forming unit (1) is capable of forming tufts from at least eight different yarns and preferably at least ten.
A carpet weaving loom according to any one of the preceding claims, in which the or each tuft forming unit (1) is capable of forming tufts from at least twenty four different yarns.
A carpet weaving loom according to any one of the preceding claims, in which the or each tuft forming unit (1) comprises a yarn selector wheel (20) with provision for holding a number of different yarns arranged around it, means (21) to drive the selector wheel (20) into a selected one of a number of angularly discrete positions to bring a selected yarn to a loading position, a puller (29) for engaging the selected yarn at the loading position and for pulling a predetermined length of the selected yarn from the selector wheel (20), and a cutting mechanism (28) to cut the selected yarn to form a tuft (7) of predetermined length.
A carpet weaving loom according to any one of the preceding claims, in which the or each tuft forming unit (1) remains stationary and the means to receive and hold the yarn tufts at yarn tuft holding sites (8, 73) is formed by a tuft carrier which moves longitudinally past the or each tuft forming unit (1).
