1. In a tufting machine including means for supporting a backing fabric moving in one direction, first and second rows of yarn carrying needles supported on one side of said backing material, each row having a plurality of laterally spaced needles, the needles in one row being spaced from the needles in the other row in the direction of movement of said backing and the needles of one row being laterally staggered relatively to the needles in the other row, means for reciprocating the needles for penetrating the backing material and forming loops therein, first and second rows of hooks supported on the opposite side of said backing material from said needles, there being one hook corresponding to and cooperating with each needle, means for oscillating said hooks toward and away from the path of the respective needle in timed relationship with the reciprocation for ceasing said loops in succession, a knife cooperating with each hook for severing loops on said hooks in succession, said means for supporting said backing material comprising a plurality of laterally spaced fingers, each of said fingers being of substantially straight members having a free end extending in the direction of movement of said backing material, the spacing between adjacent fingers accommodating said needles, alternate fingers being of a first length for supporting said material adjacent the penetration of said first needles, remaining fingers being of a second length differing from said first length substantially by the spacing between the needle rows for supporting said material adjacent the penetration of said second needles, and means for oscillating said fingers in timed relationship to said hooks from a disposition in the path of reciprocation of respective needles for supporting said material during penetration thereof to a disposition withdrawn from said path as said hooks move toward said path.
