1. Opening adjustment

The opening amount of one step twisting machine price varies with the beating stroke. There are also differences between single and double jets, flat openings and dobby openings. Too large or too small will result in warp breakage and poor weft flight. The size of the opening should be selected according to the variety requirements, raw material properties, opening mechanism and one step twisting machine price structure. It is necessary to ensure the smooth flight of the weft thread, or not affect the breakage of the warp thread.

When the one step twisting machine price is 180°, the opening amount of the flat top mechanism can be changed by moving the position of the cotter pin in the opening arm. Moving the cotter pin to the front of the machine increases the opening amount, while moving it to the rear changes the opening amount less.

There are various types of dobby discharge mechanisms. Take Japan's Murata Mx-7 as an example. The amount of shedding is determined according to the weaving conditions. The opening is small, which helps with speed. If the opening is too small, it is not conducive to the flight of the weft insertion water column. If the opening is too large, the warp may break.

2. Adjust the opening hours

The leveling off time of one step twisting machine price is usually 350°~355° for single spray and 345°~355° for double spray. Incorrect shedding time will result in poor weft insertion or warp breakage, etc. Now, Tsudakoma ZW302 is flat and falls off. For example, the adjustment method is as follows:

When the heald frame is horizontal, the height from the top of the heald frame to the guide seat of the heald frame is 138mm.

Measure the heights H11 and H21 of the guide seat from the top of the second heald frame to the horizontal (350°) of the heald frame.

When turning the handwheel to 350°, measure the heights H12 and H22 from the top of the second heald frame to the guide seat.

At 350°, adjust the open crank on the right side of the loom so that the height of each heald frame is (H11 H12)/2.

At 350°, adjust the crank on the left side of the loom so that the height of the second heald frame is (H21 H22)/2.

After completing the above operations, adjust the feet of each heald frame to 350°, and adjust the height of each heald frame to 138mm from the guide seat.
