How does the needle plate work in a computerized flat knitting machine?
The needle plate in a computerized flat knitting machine is an essential component that plays a crucial role in the knitting process. Here's how it works:
Needle Placement: The needle plate is a flat, metal plate that contains a series of small holes or slots. Each hole corresponds to a needle in the machine. The needles are inserted into these holes, with their points protruding through the plate's underside.
Stitch Formation: As the machine operates, the needle plate moves in synchronization with the needle beds. The needle plate's movement allows the needles to create loops by interlocking the yarn during the knitting process.
Yarn Guidance: The needle plate has specific grooves or guides that help direct the yarn to the needles in an organized manner. These guides ensure that the yarn follows the correct path, minimizing the chances of tangling or misplacement.
Stitch Size and Density: The design and configuration of the needle plate impact the stitch size and density of the knitted fabric. The spacing between the holes or slots determines the stitch width, while the arrangement of the holes influences the density of the stitches.
Fabric Stability: The needle plate provides support and stability to the knitted fabric as it is being formed. The fabric rests on the needle plate, allowing the needles to work smoothly and preventing any distortion or stretching of the fabric during the knitting process.
What is the role of the needle plate in the knitting process of a computerized flat knitting machine?
The needle plate plays a crucial role in the knitting process of a computerized flat knitting machine. Its primary functions include:
Needle Guidance: The needle plate guides the needles in the correct position during the knitting process. The needles are inserted into the holes or slots on the needle plate, and their points protrude through the underside of the plate. The precise alignment and placement of the needles are essential for creating accurate stitch patterns.
Stitch Formation: As the machine operates, the needle plate moves in synchronization with the needle beds. This movement allows the needles to create loops by interlocking the yarn. The needle plate provides a stable surface against which the needles can push and manipulate the yarn, resulting in the formation of stitches.
Yarn Management: The needle plate also helps manage the yarn during the knitting process. It features grooves or guides that direct the yarn to the needles in a controlled manner. The yarn follows these guides, ensuring proper tension and preventing tangling or misplacement of the yarn.
Stitch Size and Density Control: The design and configuration of the needle plate influence the stitch size and density of the knitted fabric. The spacing between the holes or slots on the needle plate determines the width of the stitches. By adjusting the arrangement and density of the holes, the needle plate contributes to achieving the desired stitch density in the fabric.
Fabric Stability: The needle plate provides support and stability to the fabric being knitted. As the needles create stitches, the fabric rests on the needle plate, preventing distortion or stretching. The stable surface of the needle plate ensures that the fabric maintains its shape and dimensions during the knitting process.
Tension Control: Along with other components of the knitting machine, the needle plate contributes to controlling the tension of the yarn. The position and movement of the needle plate play a role in maintaining consistent tension, resulting in uniform stitch quality throughout the fabric.
