Abstract
A yarn feed system (10) for a tufting machine comprises multiple pairs of feed rollers (11, 12) disposed one pair above the other. One of each pair of rollers (12) comprises multiple independent side-by-side axially aligned feed roller elements (13), each roller element (13) being mounted on a tufting machine in a releasable mounting (17, 18). In use the feed roller elements (13) can be released from the mounting (17, 18) if it is required to change the pattern to be produced in a tufted fabric or a thread breaks and the yarn feed system of the invention minimises the amount of rethreading necessary in these circumstances.
