Draw-Frame (Leveling)
A draw frame is a machine used in the textile industry to further process sliver, which is a loosely twisted strand of fibers obtained after carding. The primary function of the draw frame is to improve the quality and uniformity of the sliver before it is spun into yarn.
The sliver from the carding machine is fed into the draw frame. The draw frame consists of multiple sets of rollers and drafting systems.
The sliver passes to drafting zones in the draw frame which consists rollers that grip the sliver and stretch it, reducing the sliver's weight and increasing its length. This process is known as drafting, and it helps align the fibers and improve their parallel arrangement.
The draw frame plays a crucial role in the spinning process by improving the sliver's uniformity, reducing variations in fiber length and thickness, and aligning the fibers parallel to each other. This results in a more consistent and higher-quality sliver, which can be further processed in spinning machines to produce yarn.
The draw frame is an essential component in textile mills, especially in the production of fine or high-quality yarns, where precise control over sliver properties is crucial for achieving the desired yarn characteristics.
