-General DescriptionFB415,FB426,FB435,FB445 and FB455 threaded-rod gill boxes and FBL415,FBL426,FBL435,FBL445 and FBL455 chain gill boxes are a new generation of high-speed and efficient series gill boxes designed,developed and manu-factured by the DACHENG Textile Machinery Co.,Ltd on its own,on the basis of drawing on the features of the ad-vanced domestic and overseas gill boxes and considering the actual situation of our country. Model FB473 twistless roving frame is a finalized product developed by the company in 2000 and matches worsted series gill boxes.

-UseWith the sliver discharging speed reaching up to 150m/min and the front ratch being 28-63mm，FB series threaded-rod gill boxes are applicable to small batch and multi-variety wool fore-spinning process and are used for the pure spinning and spinning of low,medium and high-count imitation wool and fiber. With the sliver discharging speed reaching 250m/min and the front ratch being 39-63mm，FBL series chain gill boxes are especially applicable to large batch wool fore-spinning process and are used for the pure spinning and spinning of low,medium and high-count imitation wool and fiber.

Model FB473 twistless roving frame makes the canned tops into roving of certain fineness by means of drawing,drawing,drafting and slubbing,with the puality meeting the requirements of the technological process,and the roving is further made into ball tops for the use by worsted spinning frames to imitate twistless roving.

-CharacteristicsEquipped with frequency converter,PLC,touch screen,automatic contuoller,etc,and convenient to operate and maintain,FB/FBL series gill boxes and Model FB473 twistless roving frames are ideal model for wool spinning enterprises'choice.

-Technical ProcessApplication of FB/FBL series in the technical process of wool fore-spinning：FB/FBL415(with wool cream mixing bar)-FB/FBL426(with neat and well spaced primary pass)-FB/FBL435(second pass)-FB/FBL445(third pass)-FB473(rovintg)-spinning frame(for spinning low and medium-count yarn)FB/FBL415(with wool cream mixing bar)-FB/FBL426(with neat and well spaced primary pass)-FB/FBL435(second pass)-FB/FBL445(third pass)-FB/FBL455(fourth pass)-FB473(roving)-spinning frame(for spinning high-count yarn)
