High Speed Good Manufacturer Roving Frame Cotton Yarn Spinning Machine

Model JWF1436C,JWF1446C Roving Frame is the latest generation cone drumlessversionwhich is developed on the base of FA series with the microcomputer control.The regulating speed by inverter.The machine has the high level of mechanical and electrical integration.High-precision control system and in the form of four motor divisions drive, so that the whole of spinning process to achieve a digital control,with high yarn quality and high reliability.

1- HIGH SPEED
Using high-speed closed type flyer, by gear transmission.
2- HIGH EFFICIENCY AND SIMPLE OPERATION
All process data is stored and can be recalled up at any time.Except the drafting changegears,all of other change gears are eliminated.parameters are input directly on the touch screen.The technological parametrs are input directly on the touch screen.
3- PURSUITTHE HIGH QUALITY ROVING
The current inspecting and feedback controlling system are composed of CPU and multi rotary encoderswith high accuracy.
The digitallsation control is accomplished by the inverter control system with high accuracy. The rovingtension is strictly controlled during running by math. patterns to ensure the uniform roving tension. 
 

DRAFTING SYSTEM

3-roller and 4-roller double short aprons drafting system are available at option.

STANDARD CONFIGURATION:
Chinese YJ-40 Spring-loaded pendulum arme.OPTIONAL CONFIGURATION:
The pendulum arm of Texparts PK1550 and Roller bearing;Suessen Leaf spring pressure pendulum arme and Roller bearing.

CLEANING SYSTEM

The perfect self-cleaning system is presented in this machine. Upper and bottompositive intermittent revolving cloth are adopted and the traveling cleaner andsuction channel are equipped.The waste combed from the bottom clearer cloth together with the flyingsaccumulated on spindle rail cover and roller beam are all blown into the suctionoutlets which are located on the back side of roller beam .Meanwhile the wastecombed from the upper clearer cloth is suck up by the traveling suction nozzle,foreffective preventing the flyings to adhere into the roving and decreasing the rovingfaults.

CREELWITH GANTRY

The guide roller is made of the aluminium alloy with the positive feeding.The closed type ball bearings are equipped with the connecting places ofthe guide roller of each staff to eliminate the false draft.
