The Air Covering Machine, abbreviated as AC air wrapping machine, is a series of air wrapping machines developed by our company according to the market and customer's more process requirements for filament processing. This series of air wrapping machines can effectively wrap and wind general industrial silk and spandex silk through a network. The equipment disperses the wrapped filament through the airflow of the nozzle, tightly wrapping it around the wrapped yarn to form network nodes, In addition, the introduction and use of the electronic back pressure system in the winding system greatly improves the winding stability of the equipment and the consistency of the internal and external density of the rolled yarn; Precision ceramic network nozzles, oiling devices, and other optional functions can be selected according to customer production process requirements. This model is suitable for air coating or lamination processes of polyester, chemical fibers, high and low elastic fibers, and spandex fibers.
