Abstract: In a conventional tufting machine forming cut pile only, a looper is supported in a looper block sliding toward a cooperative needle, and, in each periodic time of tufting reciprocation, it is determined selectively whether a looper is pushed out from a looper block or not and whether a loop of pile yarn is seized thereby at a looper bill releasably or securely. The loop seized releasably is released from a looper and forms loop pile. The loop seized securely is not released from a looper and receives engagement of a looper and a knife to form cut pile. In order to determine selectively whether the looper is pushed out or not, a conventional pattern apparatus can be used.
