A cut pile tufting machine having cut pile hooks and cooperating knives pointing in the direction oppositely to the direction in which a base fabric is being fed includes loop pile loopers in a selective array in the same mounting bar as the cut pile hooks and also pointing in the direction oppositely to that in which the fabric is being fed. The loop pile loopers each include a yarn seizing beak having a slightly downwardly inclined rearwardly extending bottom front edge at the rear of which a yarn contacting edge extends abruptly downwardly. The yarn contacting edge engages the crotch of a loop presented by a cooperating needle as the beak enters the loop allowing the loop to be seized and then shed by the beak. The looper includes a recess in the body behind the yarn contacting edge to provide a clearance with respect to the needle eye as the beak enters the clearance above the needle eye.
A looper for forming loop pile in a cut pile tufting machine, said looper comprising a planar body member having a blade and a shank including a mounting portion for mounting in a hook bar of the tufting machine, said blade extending forwardly from the shank and terminating at an upper edge in a loop seizing beak, said beak having a downwardly inclined rearwardly extending lower edge for seizing a loop of yarn, a yarn engaging edge formed on said blade extending abruptly downwardly from the rear of the lower edge of said beak, said blade having a bottom edge extending forwardly from said shank to said yarn engaging edge.
In a tufting machine, means for feeding a base fabric in one direction, a yarn carrying needle for penetrating the base fabric and forming loops therein, a looper disposed on the opposite side of the base fabric from said needle for seizing said loops, said looper comprising a planar body member having a blade and a shank, said blade extending forwardly from the shank and terminating at an upper edge in a loop seizing beak, means for mounting said shank with said beak facing in a direction opposite to said one direction for oscillatory movement toward and away from said needle so that said beak enters successive loops, said beak having a downwardly inclined rearwardly extending lower edge for seizing a loop of yarn, a yarn engaging edge formed on said blade extending abruptly downwardly from the rear of the lower edge of said beak, said blade having a bottom edge extending forwardly from said shank to said yarn engaging edge.
