Abstract
A cut pile tufting machine having cut pile hooks and cooperating knives pointing in the direction oppositely to the direction in which base material is being fed includes loop pile loopers in a selective array in the same mounting member as the cut pile hooks and pointing in the direction oppositely to that in which the fabric is being fed. A wiper cooperates with each loop pile looper to push loops of yarn seized by the looper off the beak of the looper to form loop pile. The wipers are mounted in knife blocks with the knives and rock into loop pushing relationship with the loop pile loopers as the knives rock into cutting engagement with the loops on the cut pile hooks. The loopers have an elongated inclined blade terminating at the beak which is spaced below the cutting edge of the hook relatively to the base material. Yarn feed rolls feed less yarn to the needles that cooperate with the loopers than required so that as each loop is formed the preceeding loop is backrobbed to the same level as the cut pile.
