ABSTRACT:
A multiple needle tufting machine incorporating a pair of relatively transversely adjustable front and rear needle bars, each needle bar supporting corresponding front and rear needles in transverse rows for simultaneous penetration of a base fabric moving in a feeding direction through the machine. A looper apparatus is provided incorporating transversely adjustable front and rear loop pile hook bars supporting a plurality of corresponding front and rear loop pile hooks pointing in the direction of fabric feed. Both the front and rear needle bars and the front and rear hook bars are relatively transversely adjustable between positions in which the front and rear needles are in alignment with the direction of fabric feed and a staggered position in which the front and rear needles are transversely offset. Separate yarns of preferably different characteristics are fed to the front needles and to the rear needles preferably by pattern control mechanisms to produce loop pile fabric of various patterns.
