If there are no obstacles, stranges sounds etc. You are good to go. 

 

Functional Mode Debugging of the Hand Tufting Gun

In order to make the tufting gun in the best working order and tuft high quality pile surface, please adjust the state in advance as follows:

(1) Adjust the line of symmetry of the right cam wheel (Part No.19) to make the included angle of it and the tilting block become 45°. 

(2) Twist the left cam wheel to make the axes of the end arm bearing(Part No.8) and the axes of the gun body in parallel .

(3) Tweak the end arm bearing to make flex adjustment and make the distance between the eye of the needle and the foot shorter than 5mm. Just like the photo below.

Inspection of Open-and-close State of the Scissors

Check the open and close state of the scissors by (while plugged out) manually turning the arms to the higest position, the scissors must be closed. 

When turning the arms in the oppostite position, the scissors must be open. 

If you look closely you see that there is a bar adjusted to the foot, that causes the scissor to open at the right moment.

thirdly, tighten the trip bolt;

lastly, adjust again as the means of the above procedures of 2(1)-2(3).

 

 

The Requirement of the Edges of the Scissors and the Steel Needle

When the best functional mode of the hand tufting gun has been adjusted, but the needle and the scissor don’t reach the requirement, it can still will happen that the yarns break, fuzz and are oust-of-flatness. Therefore, the requirements of the needle and the scissors are strict.

(1)Be sure to sharpen the edges of the scissors in advance and keep them sharp-edged constantly . Control the crossing angle of the cutting edges of the scissors to be 25°-30°. It is the best that the scissors edge clearance angle is about 45°( refer to picture 5).

 (2)Close the scissor . When 2 blades of the scissors are superimposed, the cusps should be appressed, the light leakage can be seen in the middle parts of the scissor blades to make sure the cusp is powful. If possible, polish the outside surface of the scissor, besides the edges of it, with feltless polishing bob in favor of tufting level pile surface.

(3)Please inspect the steel needle before working and polish it with fine oil stone. At the same time, grind the hole of the steel needle for the suitable pore diameter according to the thickness of yarn which is subject to feed yarn glidingly.
