Yarn presser of sample warping machine

Let’s see the materials of yarn presser first. The main materials of yarn presser are purple color ceramic and silver color metal. From the below picture, you can see ceramic in 10 places, including 7 ceramic eyelets.

Why use the material ceramic?

The surface of ceramic is smooth, can protect the yarn from flying out, broken and fluffy.

The functions of ceramic in the yarn presser has been introduced, following we will introduce the other important part, metal. The metal has a perfect structure. One part of its surface has numbers from 0 to 10.

What’s the functions of numbers on the metal surface?

The numbers on the surface is the main part of yarn presser. We can control the tension by adjust the iron pointer pointing to which number. The smaller the number, the smaller the tension. Vice versa. The larger the number, the greater the tension. When the number is 0, the tension is smallest, yarn passes fastest, and yarn warped on the beam is loose and soft. When the number is 10, the tension is largest, yarn passes slowest, and the yarn warped on the beam is tight.
