ABSTRACT:
A multiple needle tufting machine in which the needles are arranged in at least two transverse rows and including first and second sets of cut pile hooks and knives cooperating to form cut pile. Both sets of cut pile hooks may be mounted in the same hook bar so that the throats of the hooks and the knives are substantially transversely aligned. The bills of the second set of hooks are longer than the bills of the first set of hooks, preferably in an amount equal to the longitudinal spacing between the transverse rows of needles, for cooperation with the needles in the respective transverse rows.
