1. A tufting machine, comprising feed rollers for supplying yarns to the needles of the machine, speed control means for causing the feed rollers to feed the yarns at alternative speeds under control of a patterning mechanism to cause the needles to form pile of different heights in different areas of the fabric to be tufted in accordance with a pattern determined by the patterning mechanism, a tube system which feeds the yarns to the needles to provide repeats of the pattern across the width of the fabric, a border control mechanism including a first counter for counting the number of repetitions of the pattern in a direction lengthwise of the fabric, a second counter for counting the number of strokes performed by the needles, means operative when the first counter has counted a predetermined number of longitudinal repeats of the pattern to free the speed control mechanism from control by the patterning mechanism so that patterning ceases and means operative when the second counter has counted a predetermined number of strokes of the needles to return the speed control mechanism to control by the patterning mechanism.
