You can understand it as a huge yarn "supply warehouse" or "stringing frame", which serves as a bridge connecting the previous preparation process and the warp knitting process.
#### ** II. Main structure of the coil head **
A typical plate head mainly consists of the following parts:
1. ** Drum body ** : The main part of the reel head is a hollow drum with a surface that is usually very smooth to prevent the yarn from being scratched. The yarn is tightly wound around the cylinder. 2. ** Side discs ** : Two huge discs installed at both ends of the cylinder. Its core function is to ** restrict the yarn layer **, prevent the yarn from falling off or becoming disordered from both sides during high-speed unwinding, and ensure the smooth progress of yarn unwinding. 3. ** Shaft Core ** : A metal shaft running through the center of the disk head, with specific structures (such as keyways, flanges, etc.) at both ends, used to install and fix the disk head on the warp frame of the warp knitting machine. 4. ** Locking device ** : It is used to firmly lock the side plate onto the shaft core to ensure that the plate head does not loosen during high-speed operation.

Introduction to Warp Knitting Machine Disk Heads
#### ** I. What is a coil? **
The "reel head", also known as the "warp shaft" in the warp knitting industry, is a key yarn feeding component on warp knitting machines. Its shape is usually a huge cylindrical or conical drum. Its core function is to continuously and stably convey thousands of warp yarns that have been parallel and evenly wound in the preparation process (such as warping) to the loop area of the warp knitting machine at a certain tension and speed, for knitting into fabric.
You can understand it as a huge yarn "supply warehouse" or "stringing frame", which serves as a bridge connecting the previous preparation process and the warp knitting process.
