modern carding machines have using the auto leveler still there can be some unevenness along the slivers. These two issues will affect the quality of the yarn. The draw frame machine is the last machine which can improve the yarn quality in the yarn manufacturing process. The tasks drafting and doubling are the objectives of the draw frame machine in order to improve the fiber orientation and sliver uniformity respectively. Removal of hooks and dust also can be carried out by the machine‚ at a significant
