Abstract
A tufting machine having two bladed hooks facing oppositely to the direction of backing material feed has a gate member associated with the lower of the blades. The opening and closing of the gate members are determined by a pattern so that each needle may selectively form a high or a low level cut pile tuft. Loops are initially seized by the bill of the lower blade. Each gate member has a latch for selectively closing or opening entry of a loop from the lower bill onto the lower blade. The upper blade has a bill overhanging the lower bill and loops precluded from entry onto the lower blade are shed by the lower bill and seized by the upper bill for entry onto the upper blade. A knife acts with each blade to cut loops thereon to form cut pile at the level of the respective blade.
