Claims

[Claims for Utility Model Registration] A yarn feeding mechanism that feeds the pile yarn 2 to the needle 1, and a needle reciprocating mechanism that pierces the needle 1 into the base fabric 3 and projects the yarn 2 to the opposite side of the base fabric 3. In the hand tufting machine equipped with the above-mentioned thread feeding mechanism, the needle 1 is made into a cylindrical shape through which the thread 2 can pass, and
Thread 2 is attached to a cylindrical needle holder 4 provided at the rear of the needle 1.
An air supply pipe 5 that pushes out the needle 1 toward the tip side is connected, and a rotating roller 8 is connected to a rotating shaft 7 driven by a drive motor.
A pressing roller 9 is provided which is pressed against the rotating roller 8 by a force of 10 springs with the yarn 2 in between, and one of the rollers 8 is set so that its outer circumference is adjusted to the pile length. The roller 8 has a length approximately equal to the sum of twice h and the width w of one stitch, and is characterized in that the roller 8 is attachable and detachable in order to be replaced with a roller 8 of this type having a different outer circumferential length. Hand tufting machine. A thread feeding mechanism that feeds the pile thread 2 to the needle 1, a needle reciprocating mechanism that pierces the needle 1 into the base fabric 3 and projects the thread 2 to the opposite side of the base fabric 3, and a thread cutting mechanism that cuts the thread 2. In the hand tufting machine, the thread cutting mechanism includes a notch on the periphery of the cylindrical needle holder 4 holding the rear part of the needle 1, perpendicular to the direction of the center line of the holder 4. 11, and a movable blade 12 in which a blade part 13 enters by rotation or reciprocation is provided in the notch part 11.
